Selective fixed-bed fischer-tropsch synthesis with high surface area Cu and K promoted, iron/manganese spinels

摘要

Pelletized, high surface area, Cu and Group IA or IIA dual metal promoted Mn-Fe spinels which are reduced and operated in a fixed- bed reactor provide exceptionally high catalytic activity and selectivity in the conversion of CO/H.sub.2 to high molecular weight hydrocarbons. These copper and Group IA or IIA metal promoted iron-manganese catalysts maintain good activity and selectivity to C.sub.5 + hydrocarbons, and give low selectivity to CO2.
