FERRIHYDRITE AND ALUMINIUM-CONTAINING FISCHER-TROPSCH CATALYSTS

摘要

This invention relates to an iron-based Fischer-Tropsch catalyst composition wherein the main iron phase is ferrihydrite and wherein the catalyst composition includes alumina as a structural promoter. The invention also relates to a process for preparing this catalyst. The use of alumina as a structural promoter in an iron-based catalyst composition wherein the main iron phase is ferrihydrite increases the activity and selectivity of the catalyst by 1.5 to 3 times.
