Process for slurry fischer-tropsch hydrocarbon synthesis with high surface area reduced-carbided iron/manganese catalysts

摘要

Slurried, high surface area, Cu and Group IA or IIA dual metal promoted Mn-Fe spinels which are fully reduced and carburized provide exceptionally high catalytic activity and selectivity in the conversion of CO+H₂ to alpha-olefins, particularly when reduced and carbided in-situ. These copper and Group IA or IIA metal promoted iron-manganese catalysts maintain good activity and selectivity under low pressure reaction conditions in a slurry bubble column reactor.
