SHS Catalysts for Purification of Exhaust Gases From Internal Combustion Engines

摘要

Efficiency of reducing the level of pollutant emission from internal combustion engines and industrial convertors depends mainly on the properites of catalysts introduced in the combustor. Catalysts for purification of exhaust gases from internal combustion engines should meet some specific requirements. On the one hand, they are to provide efficient oxidation of carbon monoxide and hydrocarbons and simultaneously reduction of nitrogen oxides at variable flow rate, gas composition, and temperature, on retention of hgih catalytic activity after prolonged use. On the other hand, the catalysts should be wear- and heat-resistant as well as provide required heat and mass exchange.
