ABSTRACT:
It was previously found that a catalyst containing molybdenum and at least one element of the lanthanide or actinide groups or mixtures thereof, at a temperature of from 300.degree. C. to 600.degree. C. and a pressure of from 100 psig to 2,000 psig was a superior catalyst for the production of methane from a feed mixture containing hydrogen, carbon monoxide and gaseous compounds of sulfur.
It has now been discovered that although the presence of alumina as an additional component had not been well characterized, it gives advantageous results when present in these methanation catalysts. Experimental data have shown that when alumina is added in small proportions to the molybdenum containing catalysts it results in further increased activity. Substantially the same temperatures, pressures and feed streams are used as in the process which does not employ the alumina in the catalysts.
