Study on carbon deposition in diesel autothermal reformer

디젤 자열개질기 내 탄소침적에 관한 연구

Diesel autothermal reforming(ATR) is an effective method for hydrogen production. But, diesel ATR has several problems such as the sulfur poisoning of catalyst and carbon deposition during reforming reactor. Especially, carbon deposition is a severe problem, which causes rapid performance degradation, in the reforming reaction. Ethylene among the reformate gas is a carbon precursor. Effective decomposition of ethylene is an important issue. In this paper, we investigated the carbon deposition from ethylene in the reforming reaction for proper reaction condition of diesel ATR. We achieved relatively high performance of diesel ATR under $H_{2}O/C=0.8$, $O_{2}/C=3$ condition that was based on the experiment of ethylene reforming reaction.
