Clearly then, catalysis is critical to two of the largest industries in sales in the United States; catalysis is also a vital component of a number of the national critical technologies identified recently by the National Critical Technologies Panel.

Department of Commerce, U. Phillips, chair, Arlington, Va. During the refining of petroleum, large hydrocarbon molecules are broken down into smaller ones in a process known as cracking.

The amount of gasoline that can ultimately be produced from a barrel of oil depends on how efficiently cracking is performed. If carried out incorrectly, cracking can lead to the formation of gases such as methane and ethane, and high-molecular-weight components called residue, which cannot be used to make gasoline or other transportation fuels. The story began in when acid-washed natural clays were first employed as catalysts. Subsequent research revealed that higher cracking efficiencies could be achieved by using amorphous silica-alumina.

In the late s and early s, significantly greater efficiencies were found to be possible by using cracking catalysts based on zeolites. These materials are crystalline solids containing pores and cavities of molecular dimensions. The interior surfaces of the zeolite contain highly acidic centers that serve as the active sites for cracking petroleum Figure 2. Mobil Corp. The use of zeolite catalysts has greatly benefited the U. Looking into the future, one can see many exciting challenges and opportunities for developing totally new catalytic technologies and for further improving existing ones.

Increasing public concern with the effects of chemicals and industrial emissions on the environment calls for the discovery and development of processes that eliminate, or at least minimize, the use and release of hazardous materials. Concern with the environment and the supply of raw materials is also focusing attention on the opportunities for recycling. Of particular interest for the chemical industry is the prospect of producing polymers that are readily recyclable.

Although the world supply of petroleum is adequate for current demand, there is a need to continue the search for technologies that will permit the conversion of. Figure 2. Figure courtesy of Union Carbide Corporation. Also, to maintain economic competitiveness, it will be necessary to shift to lower-cost feedstocks for the production of commodity and fine chemicals.

Taken together, these forces provide a strong incentive for increasing research efforts aimed at the discovery of novel catalysts and catalytic processes. The markets for industrial catalysts are usually broken down into three sectors: chemicals, fuels, and environmental protection. The same classification is used in the sections that follow to discuss new opportunities in catalytic technology.

In considering new routes to existing products, emphasis here is placed on major advances rather than on incremental improvements, even though the latter are often quite valuable and justified. With the increasing maturity of catalytic technology for most large-volume commodity chemicals, major advances in the future will require technical discontinuities. These discontinuities, as opposed to improvements in existing technologies, offer the real opportunities for catalysis to have an impact on the economy.

One can recognize and identify limits in the current technology for almost all major products made via catalytic processes. Furthermore, in most cases, at least one potential pathway to a major advance can be visualized. Each such advance constitutes a latent opportunity to shift to a lower-cost feedstock or to a simpler, less-capital-intensive route. Thus, a great financial impact can result from moving to a lower-cost feedstock.

Since its launching in , the Monsanto process has captured most of the world's new capacity for making acetic acid. Feedstock price changes in recent years have further magnified the cost advantage of the methanol carbonylation route.

By far the strongest current thrust toward lower-cost feedstocks is the effort to substitute alkanes ethane, propane, and butane for the corresponding olefins and to convert methane to olefins or aromatics.

An excellent example is the production of maleic anhydride, a monomer for specialty plastics. Over the past 40 years, advances in catalytic technology have enabled the industry to switch from high-priced, toxic benzene to butenes and, more recently, to the lower-cost hydrocarbon butane. This latter development was possible only as a result of the discovery of the vanadyl phos-. A new process for producing maleic anhydride by using novel catalyst and reactor technologies is currently under development by Du Pont and is scheduled for commercialization in the mids.

An extensive worldwide effort is now under way to develop the catalytic oxidative coupling of methane to petrochemicals as well as liquid fuels. This effort encompasses oxidative coupling of methane to ethylene or aromatics, oxidative methylation of toluene to ethylbenzene and styrene, oxidative methylation of propylene to C 4 olefins, and dehydrogenative coupling of methane to aromatics.

This area of methane conversion captured exceptional interest and attention all over the world in the mid s. The relative abundance of LPG liquefied petroleum gas, containing mostly propane and butane and the strong demand for aromatics have prompted British Petroleum BP to develop a process for the catalytic conversion of LPG to aromatics.

In another alkane utilization project, BP Chemicals is developing a process for the direct one-step ammoxidation of propane to acrylonitrile. Key to the process is a proprietary catalyst. Now at the pilot-plant stage, the process is targeted for commercialization in the mids. A new commercial development in catalytic alkane dehydrogenation relates to the production of isobutylene and of propylene. The isobutylene requirement is for the production of gasoline octane enhancers i.

Several companies have recently installed or are currently installing new plants for the production of isobutylene and propylene. In light of this remarkable development, there may also be opportunities for new catalysts that would be capable of promoting oxidative dehydrogenation of lower alkanes i.

Direct functionalization of hydrocarbons remains a very significant approach i. Catalytic dehydrogenation of paraffins is also widely practiced commercially for the production of linear olefins in the C 10 -C 17 range, used in the manufacture of biodegradable detergent intermediates.

The preparation of yet heavier olefins by catalytic dehydrogenation is also possible for specialized applications, including the manufacture of synthetic lubricating oils and oil additives. Worth noting at this point is the recent introduction of solid heterogeneous acid catalysts for the alkylation of benzene with heavy olefins in the production of LAB; this will allow the replacement of traditional catalysts, such as hydrogen fluoride HF or aluminum chloride AlCl 3 used for this purpose and will thus avoid the operational hazards associated with the handling and processing of corrosive catalysts and ameliorate the environmental characteristics of this alkylation process.

C 1 chemistry i. After the oil embargo of , there was an extensive worldwide effort to pursue C 1 chemistry for the production of chemicals as well as fuels. This effort eventually subsided when it appeared that the cost of carbon from C 1 sources such as coal and natural gas could not really compete effectively with its cost from petroleum-based sources, even at the much inflated prices of the latter.

However, it appears that some significant changes have occurred in the past decade before Iraq invaded Kuwait and that the opportunities for making chemicals via C 1 chemistry should be revisited. In particular, methanol should be considered as a feedstock. A substantial downward trend in favor of methanol can be observed. With the addition of ruthenium as co-catalyst, it is possible to achieve in situ reduction of acetaldehyde to ethanol, thus providing a new catalyst system for the homologation of methanol to ethanol.

One great challenge for catalysis has been the possibility of producing ethylene glycol via the oxidative coupling of methanol rather than the standard process based on ethylene as feedstock. Significant progress has been made recently in the catalytic oxidative dimerization of dimethyl ether to dimethoxyethane. Dimethoxyethane, in turn, should be hydrolyzable to ethylene glycol. By use of the ether rather than methanol, protection against side reactions has been achieved.

These results are an extremely interesting lead which, coupled with the favorable trends in methanol pricing, could pave the way to another major. In addition to acetaldehyde, ethanol, and ethylene glycol, other large-volume chemicals currently made from ethylene or propylene may become attractive candidates for manufacture via C 1 chemistry.

Of the different classes of catalytic reactions, hydrocarbon oxidation i. In addition to the desired partial oxidation products, significant quantities of carbon monoxide, carbon dioxide, and water are often obtained.

This results in complex and costly separations that, in turn, lead to processes with unusually high capital intensity. The annual capital expenditure for oxidation processes, per annual pound of product, is usually several times that for non-oxidative catalytic processes. Reprinted, by permission, from J. Roth, , p. Yoshida, N. Takegawa, and T. Ono, eds. Copyright by Kodansha Ltd.

Recent reports of success in these areas are tantalizing and suggest that catalytic oxidation should be one of the most important and fruitful areas for innovation in industrial catalysis. We seem to be at the threshold of several discontinuous advances.

New developments in catalysis can and will be the enabling technology that gives rise to new products in many sectors of the chemical industry. The potential impact of catalysis on new products is illustrated in the areas of polymers, pharmaceuticals, and biologically derived products.

The production of raw polymers e. In terms of fabrication into end-use articles e. Catalysis contributes to both monomer and polymer synthesis for a major part of this industry. Today, the United States has a clear advantage in polymer science. This position now yields a positive balance of trade but is undergoing significant competition from developments in Western Europe and Japan.

To ensure a continued prominent position, rather substantial advances in catalyst technology for both monomers and polymers will be required. Every polymer scientist involved with synthesis or structure-property studies has a ''wish list'' for new monomers or polymers that have not yet been able to be synthesized via clear-cut economic routes for commercial practice.

Almost every family of polymeric materials can utilize advances in catalysis, in monomer production or in the polymerization process. Changes in material requirements, environmental issues, feedstock availability and economics, and worldwide competitive pressures make future catalytic advances extremely important.

The primary area of intense catalytic activity involves the synthesis of new or improved polyolefins. This industry evolved out of the original Ziegler-Natta catalyst discovery in the s, leading to tens of billions of pounds per year of polyolefins worldwide. New catalyst breakthroughs could lead to new markets of significant volume—including diversified products such as syndiotactic polypropylene, true thermoplastic elastomers e.

Skyscrapers and bridges make our cities what they are. Airplanes, boats, and automobiles carry us anywhere in the world. Appliances fill our homes. Steel is the prime structural material in all these things.

Stanford graduate student McKenzie Hubert watches a catalyst produce bubbles of hydrogen in a small, lab-scale electrolyzer. The catalyst, cobalt phosphide, is much cheaper than the platinum catalyst used today and could reduce the cost of a process for making hydrogen — an important fuel and industrial chemical — on a large scale with clean, renewable energy. Much like a battery in reverse, an electrolyzer splits water into hydrogen and oxygen.

Handbook of Industrial Catalysts

Researchers at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have shown for the first time that a cheap catalyst can split water and generate hydrogen gas for hours on end in the harsh environment of a commercial device. The electrolyzer technology, which is based on a polymer electrolyte membrane PEM , has potential for large-scale hydrogen production powered by renewable energy, but it has been held back in part by the high cost of the precious metal catalysts, like platinum and iridium, needed to boost the efficiency of the chemical reactions. This study points the way toward a cheaper solution, the researchers reported today in Nature Nanotechnology. But most of the hydrogen produced today is made with fossil fuels, adding to the level of CO2 in the atmosphere. We need a cost-effective way to produce it with clean energy.

Catalysts, Petroleum and Chemical Process

Catalysts are substances that speed up reactions by providing an alternative pathway for the breaking and making of bonds. Key to this alternative pathway is a lower activation energy than that required for the uncatalysed reaction. Catalysts are often specific for one particular reaction and this is particularly so for enzymes which catalyse biological reactions, for example in the fermentation of carbohydrates to produce biofuels. Much fundamental and applied research is done by industrial companies and university research laboratories to find out how catalysts work and to improve their effectiveness. Further, it may be possible to reduce the amount of reactants that are wasted forming unwanted by-products. If the catalyst is in the same phase as the reactants, it is referred to as a homogeneous catalyst. A heterogeneous catalyst on the other hand is in a different phase to the reactants and products, and is often favoured in industry, being easily separated from the products, although it is often less specific and allows side reactions to occur.

Catalysis in industry

The first time a catalyst was used in the industry was in by J. Hughes in the manufacture of lead chamber sulfuric acid. Since then catalysts have been in use in a large portion of the chemical industry. In the start only pure components were used as catalysts, but after the year multicomponent catalysts were studied and are now commonly used in the industry. In the chemical industry and industrial research, catalysis play an important role. Different catalysts are in constant development to fulfil economic, political and environmental demands. When using a catalyst, it is possible to replace a polluting chemical reaction with a more environmentally friendly alternative.
