Abstract
A Fischer-Tropsch C -C olefin stream is treated to lower the oxygenate content to below 4000 ppm. Another Fischer-Tropsch fraction is hydrotreated and hydrocracked to provide an isobutane-containing stream. The treated C -C olefin stream is reacted with the isobutane stream in an alkylation reactor to provide a highly branched, high octane isoparaffinic alkylate. The alkylate is useful as a blending component in motor gasoline.
