3-6-2 ZnZSM-5-Al₂O₃複合担体担持NiMo硫化物触媒によるオレイン酸メチルの環化脱水素化分解反応

抄録

Dehydrocyclization-cracknig of methyl oleate (OM), one of FAME model compounds, into hydrocarbons, especially aromatics, which includes hydrocracking of OM and dehydrocyclization of alkyl fragments formed, was investigated using ZnZSM-5-Al₂O₃composite-supported NiMo sulfide catalysts in a fixed bed flow reactor. The effects of loading amounts of NiMo, the mixing ratio of ZnZSM-5 to alumina and temperature on the catalytic activity and the product selectivity were examined. At 450oC almost all catalysts exhibited 100% of conversions and the product distributions could be changed by choosing the appropriate amounts of NiMo loading and the mixing ratio of Zn-exchanged ZSM-5 to alumina. Using 9.3NM/Zn(13)Z(24)35A catalyst, the yield of aromatics reached 20 wt% at 450°C.
