Abstract:
1. A process for producing hydrocarbons, comprising contacting a feed stream comprising carbon monoxide and hydrogen with a catalyst so as to convert at least a portion of the carbon monoxide to the hydrocarbons comprising hydrocarbons with at least 5 carbon atoms per hydrocarbon molecule (C 5+ hydrocarbons), wherein the catalyst comprises a Fischer-Tropsch catalytic metal and a support comprising an amorphous silica-alumina having a bimodal pore size-distribution comprising a first mode between about 4 nm and about 10 nm and a second mode between about 10 nm and about 20 nm, and further wherein the productivity in C 5+ hydrocarbons is from 370 g C 5+ /hr/kg cat to 660 g C 5+ /hr/kg cat .
