In a process for producing a mixture of hydrocarbons rich in benzene, toluene and xylene, a fossil fuel is converted to a Fischer-Tropsch synthesis gas containing oxygenated hydrocarbons and the resultant synthesis gas is then converted by Fischer-Tropsch reaction to a product containing oxygenates and hydrocarbons. The Fischer-Tropsch product is then contacted with a catalyst comprising a metal-promoted porous crystalline zeolite having a constraint index within the range of 1 to 12 and a silica to alumina ratio of at least 12 to produce an effluent stream rich in benzene, toluene and xylene. The benzene, toluene and xylene are subsequently removed from said effluent stream. |
