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 on conditions are also described.
Claims12
A catalyst for converting low carbon number aliphatic hydrocarbons to higher carbon number hydrocarbons 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, clromium, molybdenum and mixtures thereof, and where the rhenium is present in an amount of about 3 to about 20 wt. % of the support.
A process of preparing a catalyst for converting low carbon number aliphatic hydrocarbons to higher carbon number hydrocarbons comprising a porous support having dispersed thereon rhenium and a metal selected from the group consisting of iron, cobalt, vanadium, manganese, gallium, zinc, chromium, molybdenum and mixtures thereof, the process comprising impregnating the support with a rhenium compound and a metal compound, calcining the impregnated support at calcination conditions to give a calcined product and treating the calcined product with a gas selected from the group consisting of hydrogen, methane and mixtures thereof at treatment conditions to give the catalyst.
