NEW DESIGN OF EXHAUST GAS PURIFICATION CATALYST FOR AUTOMOBILES

Abstract

The article presents a catalytic converter of exhaust gases, its purpose is to oxidize harmful compounds. The design of the catalyst is simple, but the content of precious metals does not affect the cost of the catalyst in the best way. The author put forward the idea of developing and creating a mock-up of a device for cleaning harmful emissions based on a catalytic converter that can accelerate oxidative and reducing processes when emissions containing sulfur oxides, nitrogen, carbon monoxide pass through them. At the same time, these pollutants are converted by them to harmless substances – N2, CO2, H2O, S, etc. The developed device combines two methods of cleaning gas emissions - catalytic, achieved due to the presence of various heavy metal ions that can accelerate the oxidation/reduction of toxic gases to harmless substances, as well as sorption, due to the high absorption properties of minerals. Absorption purification plays an important role, as it delays soot and hydrocarbons, which may reduce the efficiency of the catalytic process, in addition, the gas emission is cleaned more completely.
