海报摘要

Methane is 28 times more potential greenhouse gas than CO2, and its amount in the atmosphere has been increasing yearly. The indirect ways for methane conversion include dry reforming, steam reforming, bi-reforming, tri-reforming, and partial oxidation of methane (POM). Methane dehydroaromatization (MDA) is a direct way to convert methane into aromatics. Aromatics are employed to make plastics polymers, polystyrenes and styrenic products such as SBR latex and ABS nitrobenzene production. This work utilizes a molybdenum-supported coal waste material catalyst (CWM). Here the coal waste material is the source of silica & alumina. The methane conversion is 8%, and the selectivity for the benzene is more than 85% at 700°C & GHSV 1700 mlg-1h-1 with 0.3gm catalyst. The feed ratio for the reaction CH4:N2=4:1. The coke deposition in our catalyst is 5% lesser compared to the well-known catalyst Mo/ZSM-5 for MDA reaction.
