Catalytic purification of gas emission using complex metaloxide CuOMnO2

[摘要] The article presents the results of a study of catalytic purification processes from carbon and nitrogen compounds in order to reduce the contamination of surface layers of atmospheric air. The article proposes a method for producing heterogeneous catalysts based on copper and manganese for purification of waste gases from carbon monoxide, nitrogen dioxide and methane. The studied conditions for the preparation of the catalyst by the multistage pyrolysis method in the temperature range from 250-8,500C. The efficiency of using heterogeneous catalysts, based on complex oxides in laboratory conditions, was estimated. The amount of pollutants in the waste gases before and after the catalysis was determined. It has been established that the introduction of catalytic purification to suppress gas emissions will improve the quality of waste gases. In addition, the proposed action will reduce the damage from air pollution. All this will ultimately lead to the stabilization of the ecological situation in the region and the reduction of costs, associated with environmental payments.
