Abstract
Abstract A method for synthesizing hydrocarbons from carbon monoxide and hydrogen by contacting said gases with a slurry of a catalyst composed of palladium or platinum and cobalt supported on a solid phase is disclosed. The catalyst is prepared by heating a heterogeneous component of the palladium or platinum deposited on the solid support in a solution of cobalt carbonyl or precursors thereof. The catalyst exhibits excellent activity, stability in air, and produces highly desirable product fractions even with dilute gaseous reactants.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
84 words
A method for synthesizing principally normally liquid liner paraffinic hydrocarbons in an organic solvent comprising contacting a mixture of hydrogen and carbon monoxide with a slurry of a catalyst prepared by the process of immersing a heterogeneous component, composed of palladium or platinum or mixtures thereof deposited on a solid phase, into a solution of cobalt carbonyl or cobalt carbonyl precursors which on heating form the cobalt carbonyl, and heating the resulting mixture at a temperature from about 100° to 350° C. under pressure.
Claim 2
Independent Claim
84 words
