摘要: An extruded nickel oxide on refractory oxide hydrogenation catalyst, having, in its reduced state, a nickel surface area greater than 30 m.sup.2 /gm of reduced nickel in the catalyst and 15 to about 65 volume percent of pores having diameters of about 300 to about 1000 angstroms, is highly active for the hydrogenation of aromatics in heavy hydrocarbon streams and is relatively resistant to sulfur poisoning.

摘要: A method is provided to promote, stabilize and strengthen metal catalysts used in the fluidized bed process for methanol synthesis which comprises the dipping of such catalysts into an alcoholic solution of metal alkoxide salt. The resulting improved catalyst is characterized by high density, low loss on attrition, and improved stability and catalytic activity.
