ABSTRACT:
A composition is presented for a catalyst useful in the selective hydrogenation of unconjugated diolefinic hydrocarbons to monoolefinic hydrocarbons. The catalyst comprises nickel and sulfur deposited on the surface of an alumina support. The preferred catalyst does not contain halogens, noble metals, alkaline earth metals, or alkali metals and is characterized by having only a very low percentage of the total pore volume being provided by pores having an average pore diameter less than 150 angstroms. The great majority of the pore volume is present in the form of macropores having diameters of 500 to 1500 angstroms.
