Abstract
A catalyst for producing higher carbon number hydrocarbons, e.g., benzene from low carbon number hydrocarbons such as methane has been developed. The catalyst comprises a porous support such as ZSM-5 which has dispersed thereon rhenium and a promoter metal such as iron, cobalt, vanadium, manganese, molybdenum, tungsten and mixtures thereof. A process for preparing the catalyst and a process for converting low carbon number aliphatic hydrocarbons to higher number hydrocarbons in the presence of CO or CO2 at conversion conditions are also described.
Claims5
A process for converting low carbon number aliphatic hydrocarbons to higher carbon number hydrocarbons comprising contacting a feedstream containing at least methane with a catalyst in the presence of CO, CO2 or mixtures thereof at conversion conditions to produce the higher carbon number hydrocarbons wherein said catalyst consisting essentially of a porous support selected from the group consisting of ZSM-5, FSM-16 and mixtures thereof, having dispersed thereon rhenium and a promoter metal selected from the group consisting of iron, cobalt, vanadium, manganese, gallium, zinc, chromium, molybdenum and mixtures thereof, and where the rhenium is present in an amount of about 3 to about 20 wt. % of the support.
