PROCESS FOR THE PREPARATION OF GASOLINE COMPONENTS FROM OLEFINS

摘要

A process for the production of gasoline range products from C3 to C6 alkenes which comprises two steps: (a) passing a feed containing the C3 to C6 alkenes and water in a molar ratio of alkene to water of from 3:1 to 90:1 over an acid hydration catalyst under hydration conditions to form a product containing oligomers of the alkenes, ethers and optionally alcohols and (b) reacting alkenes containing branching at a carbon atom bearing a double bond with a C1 to C6 alcohol to form ethers. The steps (a) and (b) can be performed in either order and can be followed by a third step (c) in which unreacted C3 to C5 alkenes are alkylated with isobutane in an alkylation step.
