ABSTRACT:
A process is provided for dimerization of light olefins comprising from 2 to 4 carbon atoms which comprises contacting same at a weight hourly space velocity of from about 0.1 to about 10, a temperature of from about 32.degree.F to about 350.degree.F and a pressure of from about 200 psig to about 1000 psig with a catalyst of alumina having intimately combined therewith from about 2 to about 5 weight percent nickel and from about 1 to about 3 weight percent sulfur as a result of impregnation with nickel sulfate, said alumina being gamma, eta or a mixture thereof and said catalyst having been calcined at a temperature of from 750.degree.F to about 1150.degree.F in an inert oxygen-free, non-reducing atmosphere.
