Abstract: Isoparaffins and olefins are alkylated by contact with a solid superacid such as sulfated zirconia optionally containing added metals, and containing added heteropolyacids (HPA's) or polyoxoanions (POA's). The presence of HPA's or POA's in the solid superacid catalyst results in higher yields of desired high-octane components in the product mixture than are obtained in the absence of HPA's or POA's.

Abstract: Isoparaffins and olefins are alkylated in the liquid phase by contact with a solid superacid such as sulfated zirconia containing heteropolyacids or polyoxoanions. High octane number blending components for motor fuel and other valuable products are obtained, with important advantages over processes using liquid acid catalysts, and over vapor phase alkylation with solid superacid catalysts.

Abstract: A process is provided for the enhanced recovery of oil with steam in reservoirs containing high concentrations of dissolved salts, wherein certain diaryl sulfonated surfactants are employed in conjunction with the steam which posses high tolerance for said salts. These surfactants are comprised of compositions having (1) two aromatic rings in their nucleus, such as diphenyl, diarylalkane, or naphthalene groups; (2) at least one alkyl group having 18 or more carbon atoms; and a second alkyl group having from 1-4 carbon atoms; and (3) two functional groups comprising at least one and preferably two sulfonate groups, although one of the sulfonate groups may be replaced with a carboxyl or hydroxyl groups. At least about 65% of the diaromatic compounds should contain two functional groups, preferably sulfonates, with the remainder comprising a monofunctional-substituted compound containing either a sulfonate group, a carboxylate group, or an hydroxyl group.

Abstract: Alkylaromatic sulfonates, and particularly dialkylaromatic sulfonates, useful as surfactants in steam recovery methods for enhancing oil recovery from subterranean formations, have been found to comprise mixtures of meta- and para-isomers of the same obtained by alkylating alkylaromatics, where the alkyl group has from 1 to 4 carbon atoms, with a C.sub.14-30 olefin. It has been found that when the ratio of para-isomer to meta-isomer is increased in this mixture, a significantly more hydrolytically, thermally stable surfactant under steam recovery operating conditions is obtained.
