Abstract

A continuous multistage process for preparing gasoline and/or distillate range hydrocarbons from lower molecular weight oxygenate feedstock wherein hydrocarbon yield is increased by recovering a vapor stream rich in ethene from an oxygenates conversion stage and reacting the ethene in a high severity reaction zone containing high activity zeolite catalyst.
