Selective catalysts and their preparation for catalytic hydrocarbon synthesis.

摘要

Supported catalysts for Fischer-Tropsch processes prepared by contacting a suitable support with a catalyst in the form of a metal salt and depositing the catalyst on the support. Where rim type catalyst are preferred, a molten salt starting material is used. For non-rim type catalyst, such as powdered catalyst, catalytic metal salt-solution starting materials may be used. The catalyst is prepared without high temperature calcination of the catalyst before reduction by reducing the salt directly on the support to the metal. During the reduction step, the heating rate is a slow single steady heating rate.
