Abstract
An improved process is described for the catalytic oligomerization of light olefins, such as ethylene or propylene. Higher hydrocarbons, such as gasoline grade hydrocarbons, are produced from the light olefins using a liquid catalyst which comprises a Lewis acid and a Lewis base component which forms with the Lewis acid a melt which is liquid at room temperature. The Lewis acid is a metal halide, such as aluminum trichloride and the Lewis base is an organic salt, such as an organic halide salt containing an N-heterocyclic ring or salts containing fully substituted onium ions.
