11 Claims

1. A process for converting one or more C₂-C₈linear or branched olefins derived from one or more C2-C5 alcohols to one or more C₈-C₂₄hydrocarbons, the process comprising:

contacting a feed stream comprising the one or more C₂-C₈linear or branched olefins and at least 1000 ppm of an oxygenate, with a Chabazite zeolite catalyst at a temperature of 150 to 200° C., a pressure of 200 to 300 psig and a WHSV of between 2 and 3.2; and

forming the one or more C₈-C₂₄hydrocarbons, wherein a yield of the one or more C₈-C₂₄hydrocarbons is at least 90% and a selectivity of C₈to C₁₂and larger oligomers is at least 0.35:1, wherein the oxygenate comprises water and at least one alcohol and the Chabazite zeolite catalyst comprises TiAPSO-34.
