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.
Claims11
In a method for dimerization of an olefin feed of 2 to 4 carbon atoms which comprises contacting said olefin under olefin dimerization conditions including a temperature of from about 32.degree.F to about 350.degree.F, a pressure of from about 200 psig to about 1000 psig and an olefin weight hourly space velocity of from about 0.1 to about 10 with a catalyst of alumina selected from the group consisting of gamma alumina, eta alumina and a mixture thereof having intimately combined therewith nickel and sulfur as a result of impregnation with nickel sulfate, the improvement wherein said catalyst of alumina has intimately combined therewith from about 2 to about 5 weight percent nickel and from about 1 to about 3 weight percent sulfur, and has been calcined at a temperature of from 750.degree.F to about 1150.degree.F in an inert non-reducing atmosphere.
