Abstract
A process for the synthesis of higher hydrocarbons from the reaction of CO and hydrogen at low pressure is proposed in the contact presence of a catalyst comprising as the active ingredients a major amount of cobalt and a minor amount of ruthenium.
Claims12
A process for the conversion of synthesis gas consisting essentially of CO and H.sub.2 to a product consisting essentially of hydrocarbons and having only minor amounts of methane which comprises contacting said synthesis gas at a temperature of from 60.degree. to 450.degree. C. and a pressure from atmospheric to 300 psig with a catalyst consisting essentially of a major amount of cobalt and a minor amount of ruthenium as the active catalytic components and where in said catalyst the amount of cobalt is from 1 to 50 weight percent, calculated as the metal, and where in said catalyst the molar ratio of cobalt to ruthenium is from 5:1 to about 200:1 and thereafter recovering a product having less than 25 percent methane.
A process for the conversion of synthesis gas consisting essentially of CO and hydrogen to a hydrocarbon product substantially methane-free, which comprises contacting said synthesis gas at a temperature from 160.degree. to 350.degree. C. and a pressure from atmospheric to 50 psig, with a catalyst consisting essentially of a major amount of cobalt and a minor amount of ruthenium distended in a uniform, thin layer on a catalyst support, and where in said catalyst the amount of cobalt is from 10 to 35 weight percent of the total catalyst and wherein the the molar ratio of cobalt to ruthenium in the finished catalyst is from 15:1 to 80:1, and thereafter recovering a hydrocarbon product substantially methane-free.
