<p>A Fischer-Tropsch C3-C4 olefin stream is simultaneously dehydrated and isomerized in a reactor (40) to convert alcohols to olefins and 1-butenes to 2-butenes and thereby lower the oxygenate content. Another Fischer-Tropsch fraction is hydrotreated and hydrocraked in a reactor (70) to provide an isobutane stream. The treated C3- C4 olefin stream having an oxygenate content less than 4000 ppm is reacted with the isobutane stream to provide a highly branched, high octane isoparaffinic alkylate. The alkylate is useful as a blending component in motor gasoline.</p> |
