Abstract

The invention relates to a process for the oligomerization of mixtures of (C2-C5) alpha olefins or (C3-C5) alpha olefins isolated to produce liquid olefin oligomers which have a high viscosity index and a region regularity of not more than 40%, usually between 20 and 40%. Useful lower hydrocarbon fractions such as gasoline and distilled fuels are not also produced. The process comprises contacting the mixtures or (C3-C5) alpha olefins with a chromium oxide catalyst having reduced valency states on a silica support in an oligomerization zone under oligomerization conditions which comprise a temperature between 90 and 250 degree C. The process can be performed with dilution using an inert solvent such as octane. The liquid oligomerization products can be produced in a wide range of viscosities which include the direct production of low viscosity lubricants having a high viscosity index.
