개질 반응 특성의 이해를 통한 디젤 개질기의 성능개선에 관한 연구

Abstract

Reforming reaction can be largely divided into two parts. One is catalytic reaction(CR) and the other is non-catalytic reaction(NCR). A large amount of hydrogen is produced by CR. Therefore solid surface chemistry is used to understand how to reform fuels. On the other hand, NCR usually happen before reaching catalyst bed due to non-uniform mixing of reactants, which causes to make aromatics and olefins which are well known as hard fuels to be reformed. In addition, the reduction of the oxygen content during NCR makes surface kinetics slow down. On the basis of these understanding, we concentrated on how to reduce NCR. So we have tried to atomize diesel using ultrasonic device. Finally we have enhanced reforming efficiency at 20%.
