ABSTRACT:

The performance of an iron-copper Fischer-Tropsch catalyst was studied in a slurry CSTR at 227 exp 0 C and 790 kPa (100 psig). Catalyst performance was similar to other iron-based catalysts studied previously with respect to conversion of CO, conversion of CO + H sub 2 , and to the product distribution. CO conversion increased with decreasing space velocity, ranging from approximately 60% at 1570 h exp -1 to over 90% at 488 h exp -1 . The H sub 2 to CO usage ratio was approximately 0.7, indicating that the catalyst is a good water-gas shift catalyst as well as a Fischer-Tropsch catalyst. Reaction products could be described by a Flory distribution with a chain growth probability ( alpha ) of 0.67, which is in the gasoline range. In some runs, methanol was added continuously to the reactor feed, but instead of being incorporated into the reaction, the methanol oxidized and deactivated the catalyst. 31 references, 12 figures, 10 tables.
