Patent No. 10,316,254

Description:
The patent of a metal sulfide catalyst maximizes conversion of CO to products while maintaining high selectivity for C6-C8 chain length alcohols.

Abstract:
Certain embodiments are directed to method for making and using an alkali promoted transition metal sulfide Fischer Tropsch catalyst. Certain embodiments are directed to alkali promoted transition metal sulfide Fischer Tropsch catalyst synthesized using steps comprising (i) mixing an ammonium tetrathiomolybdate (ATM) precursor compound with an alkali metal compound and molybdenum disulfide in deionized water to form a reaction mixture, (ii) heating the reaction mixture at a temperature of at least 200, 250, 300, 350, 400C at a pressure of at lease 900, 1000, 1100, 1500, 2000 psi for more than 0.5 1, 1.5, 2.0, 3 or more hours to form a reaction product, (iii) filtering, washing, and drying the reaction product. In the Fischer-Tropsch reaction, synthesis gas, hydrogen (H2) and carbon oxide (CO), can be converted to hydrocarbons in the presence of a heterogeneous catalyst to produce a hydrocarbon mixture having a relatively broad molecular weight distribution. This metal sulfide catalyst maximizes conversion of CO to products, while maintaining high selectivity for C6-C8 chain length alcohols.
