CATALYST TECHNOLOGY DEVELOPMENTS SPARKED BY 'GREEN' AND ECONOMIC ISSUES

 FALLS CHURCH, Va., July 14 /PRNewswire/ -- Technology Catalysts International Corporation issued the following:
 Major changes in the chemical process industries are being driven by the development of new generations of catalysts which lower product/process costs and reduce the impact on the environment. Several process industry sectors, in particular, will benefit from these developments:
 -- In petroleum refining, new catalysts are needed to meet reformulated gasoline requirements, improve overall operating economics and permit refiners to process heavier, sour crude oils.
 Example: A new solid superacid catalyst was successfully tested for the isomerization of n-butane and was found to be more active than sulfated zirconia by greater than two orders of magnitude.
 -- In chemical processing, a variety of unit processes will be based on new catalysts with higher activity, enhanced selectivity, increased conversion rates and longer life. Processes include:
 - hydrogenation - oxidation
 - dehydrogenation - hydroformylation
 - carbonylation - asymmetric syntheses
 Example: A novel alloyed catalyst (containing Pd-Ag-Re supported on high-surface-area graphitic carbon) increases selectivity in the hydrogenation of unsaturated dicarboxylic acids and anhydrides. The catalyst minimizes the formation of methane and ethane, typically formed with traditional copper-based catalysts.
 -- Catalysts developed for environmental control will aid in the destruction of VOCs, SOx and NOx from stationary sources, improve groundwater purification techniques and promote reduction of sulfur content of motor fuels.
 Example: A new palladium catalyst is capable of decomposing 72.8 percent of NOx. Activity is higher than that of copper or platinum catalysts.
 These technological developments and trends are discussed by Technology Catalysts in their Technology & Business Review, "Catalysts for the Process Industries." In addition to providing an overview of the market, the report reviews the commercial and technical activities of over 100 companies and research organizations worldwide. Further, over 70 specific business opportunities are identified; these may take the form of a license, joint venture, acquisition or source for contract research.
