A Study on NO Reduction Mechanism Caused by Thermal Cracking Hydrocarbons during Diesel Combustion

Abstract

Thermal cracking and oxidization process of diesel fuel in an atmospheric pressure and high temperature place were investigated using flow reactor. When NO gas is introduced under oxidation condition of Solvent, NO is reduced upto 60% by thermal decomposed hydrocarbons. C_2H_4,which is main component of thermal cracking hydrocarbons, reduces NO upto 80%. According to the numerical simulation using CHEMKIN III, reduction mechanism of NO by thermal crackin hydrocarbon is depended on formation of HCCO and CH_2. In addition, C_2H_2 formation process plays an important role to produce HCCO and CH_2.
