Abstract:
A process for converting hydrocarbons comprising the steps of:a) introducing a hydrocarbon feed mixture comprising cracked gasoline and a first diluent comprising isopentane to a reaction zone, said reaction zone contains a catalyst composition comprising a zeolite and a phosphorus component and is operated under reaction conditions for converting hydrocarbons to light olefins; b) withdrawing from said reaction zone a reactor effluent comprising light olefins and BTX; and c) controllably introducing a second diluent comprising propane into said reaction zone in an amount such that the mole ratio of said diluent to said first diluent is in the range of from about 1:0.1 to about 1:10, whereby the percent conversion of said first diluent is enhanced over the percent conversion of said first diluent when there is no step c.
