摘要:
Synthesis gas comprising carbon monoxide and hydrogen is converted to a liquid hydrocarbon by contacting the synthesis gas under conversion conditions with a supported cobalt-ruthenium catalyst in which the cobalt to ruthenium molar ratio is greater than about 200:1. The catalyst is preferably prepared by using a non-aqueous impregnation solution and using an activation procedure involving reduction, oxidation and reduction.

Synthesis gas is converted to a gasoline boiling range product high in branched chain paraffins and olefins utilizing a catalyst consisting essentially of (A) silicalite and (B) cobalt, preferably promoted with a Group IIIB or IVB metal oxide on an alumina support of gamma-alumina, eta-alumina or mixtures thereof.
摘要:
Synthesis gas is converted to diesel fuel and a high octane gasoline in two stages. In the first stage the synthesis gas is converted to straight chain paraffins mainly boiling in the diesel fuel boiling range utilizing a catalyst consisting essentially of cobalt, preferably promoted with a Group IIIB or IVB metal oxide, on a support of gamma-alumina, eta-alumina or mixtures thereof. A straight chain paraffin portion of the effluent in the C.sub.5 -C.sub.9 range is converted in a second stage to a highly aromatic and branched chain paraffinic gasoline using a platinum group metal catalyst.

摘要:
Synthesis gas conversion catalyst prepared from synthetic layered aluminosilicate having a montmorillonite-type structure and containing cobalt substituted in the crystal lattice are activated for the conversion of synthesis gas by a sequential reduction, oxidation and reduction treatment. A Group VIII noble metal such as ruthenium can be impregnated on the catalyst prior to the final reduction stage. The catalyst is used in the production of liquid hydrocarbons from synthesis gas.
