Hybrid fischer-tropsch catalysts and processes for use |
摘要 |
Disclosed are hybrid Fischer-Tropsch catalysts containing cobalt and ZSM-48 zeolite. The hybrid Fischer-Tropsch catalysts can contain cobalt deposited on ZSM-48 extrudate supports. Alternatively, the Fischer-Tropsch catalysts can contain cobalt deposited on supports mixed with ZSM-48 particles. It has surprisingly been found that the use of hybrid Fischer-Tropsch catalysts containing ZSM-48 zeolite in synthesis gas conversion reactions results in improved C5+ productivity and catalyst activity, as well as a desirable product distribution including low formation of methane and C21+. |

1. A method of performing a Fischer-Tropsch synthesis gas conversion reaction, the method comprising:
a. contacting a hybrid Fischer-Tropsch catalyst comprising a Fischer-Tropsch metal component selected from cobalt, iron and ruthenium and a ZSM-48 zeolite component with synthesis gas comprising hydrogen and carbon monoxide at a ratio of hydrogen to carbon monoxide of from 1 to 3 at a temperature of from 180 to 280° C. and a pressure of from 5 to 30 atmospheres to yield a hydrocarbon product containing less than 8 weight % C21+ and at least 60 weight % C5+ at a C5+ productivity of at least 0.25 mLC5+/gcat/h. |
