Catalyst

Cost-effective Production Technology of Catalyst Systems for Hydrogenation Processes in the Petrochemical Industry and Organic Synthesis

The development of catalytic systems with the active centers based on refractory transition metals is one of the problems of modern inorganic chemistry. A lot of different methods of obtaining composite materials are known, like copper-diamond composite; tungsten-copper composite protected with metal rhenium, obtained by CVD-method that was enhanced with plasma for the details of rockets; obtaining rhenium-tungsten carbide composite and many others. Therefore, a process has been developed applying catalytic-active copper-rhenium composite material low-temperature with gas-phase thermal decomposition of organometallic compounds.
Method of gas-phase deposition of coatings, that was opened by English chemist Mond in 1889 and now is known as CVD-method (chemical vapor deposition), is one of the most perspective methods for coatings for today. Despite the fact, how much time ago CVD-method was opened, still there is a problem of choosing the starting materials for its implementation. Such compounds must satisfy following requirements: high volatility at relatively low temperatures of CVD-process, stability below operating temperature of process, high vapor concentration sufficient to achieve optimal growth rate of the metal deposit.
Such requirements are satisfied with chlorcarboxylates of dirhenium(III), which we offer for Obtaining of rhenium composite materials, rhenium coatings, high pure refractory metals, rhenium catalysts, other catalytic systems for hydrogenation of ethylene and restoring mixture carbon with hydrogen into methane, for anticorrosive coatings, for neutralization ecological dangerous emissions.
