The simplest means to blend methanol into gasoline is to indirectly transform it into ethers by reaction with olefins contained in the C/sub 4/ and gasoline fractions. The need to investigate nonpetroleum-derived compounds is due to federal measures to reduce polluting emissions and to progressively suppress lead alkyl additives. Tables give octane of typical refinery streams and economics of MTBE-TAME (and heavier ethers) joint synthesis from FCC. In the case of a mixed (4-light gasoline FCC feed, with a typical 48% C/sub 4/ fraction containing 15% isobutene, and a 52% light gasoline fraction containing 10.5% isoamylenes, 6.5% isohexenes and 4% isoheptenes, the C/sup +//sub 5/ gasoline products obtained at the bottom contains 16.5% MTBE, 8.5% TAME, 3.9% ethers from C/sub 6/ olefins and 1.5% ethers from C/sub 7/ olefins.
