Chemicals from synthesis gas

摘要

This invention relates to an iron-based Fischer-Tropsch cataylst composition wherein the iron phase is ferrihydrite. The catalyst composition optionally includes a structural promoter which may be selected from manganese or chromium or a mixture thereof and chemical promoters selected from magnesium, zinc, copper and an alkaline or alkali metal such as potassium. The catalyst is best bound to a refractory oxide support such as silica. This catalyst composition produces significant yields of higher parafins, olefins and alcohols.
