A hydrogenation catalyst which is sulfur tolerant and which includes from about 0.1 to about 1 percent platinum by weight and from 0.2 to about 2 percent by weight palladium on a predominantly theta alumina carrier. Also disclosed is a process for the manufacture and use of the hydrogenation catalyst.

Hydrogenation catalysts

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.

Nickel hydrogenation catalyst

An improved catalyst for the high temperature shift reaction especially suited for low steam to gas ratio applications is made by dipping an iron oxide-chromium oxide catalyst in an aqueous copper salt solution, drying the catalyst and calcining it.
