Abstract: The invention provides a method for reducing methane formation when hydrocracking hydrocarbons, and a process for the hydrocracking of hydrocarbons, said method and process utilising a non-sulfided hydrocracking catalyst, which catalyst has Ni and Sn, wherein the Ni content is at least 1 mass % and the silica content is at least 20 mass %, present in the form of silica-alumina.

Abstract: 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.
