Wood, C D; Gleason, E F

This patent describes a process for producing hydrocarbons by contacting carbon monoxide and hydrogen at reactive conditions. The improvement described here consists of increasing the yield of methane by contacting the carbon monoxide and hydrogen with a catalyst consisting essentially of: (a) a catalytic metal component which is from about 0.1 to about 10 percent by weight, based on the weight of the catalyst, of ruthenium; and the balance being (b) a support component which is at least one oxide of tantalum, niobium, vanadium or mixtures thereof, the support preparation including calcination at a temperature such that essentially no crystalline metal oxide is detectable by X-ray diffraction prior to deposition of the catalytic metal thereon.
