Process for producing gasoline

摘要

A process for production of gasoline comprising oligomerizing a C2-C6 olefin containing feedstock over an intermediate pore size siliceous crystalline molecular sieve catalyst. The catalyst may take the form of silicalite, halogen stabilized silicalite, or a zeolite. Water may be supplied to the oligomerization reaction. The product from the oligomerization reaction is then subjected to an etherification reaction in the presence of methanol over an acid cation exchange catalyst to provide a gasoline product of enhanced octane number.
