Patent ID: 8163808

Claim:
A method for converting syngas to Fischer-Tropsch (F-T) hydrocarbon products with minimal amounts of wax, the method comprising: (a) generating acetylene and synthesis gas from natural gas; (b) separating the acetylene and synthesis gas stream into an acetylene rich mixture comprising a molar ratio of acetylene to synthesis gas of 3-4; (c) providing the acetylene rich mixture to a F-T reactor; (d) reacting the acetylene rich mixture under suitable reaction conditions, in the presence of a catalyst, to produce F-T hydrocarbon has a wax fraction C21+ of less than 5%; (e) separating the F-T hydrocarbon products into gaseous F-T products and liquid F-T products pumpable at ambient temperature; and (f) recovering the F-T liquid products pumpable at ambient temperature.
