Abstract: A process is described for preparing a water-soluble sulphonated dispersant from a petroleum hydrocracking residue comprising: contacting a petroleum hydrocracking residue boiling above 524.degree. C. with concentrated sulphuric acid, oleum or sulphur trioxide to form a sulphonated mixture containing water soluble and water insoluble products, and separating the water soluble sulphonated product from the mixture. The mixture of water soluble and water insoluble sulphonated products is neutralized with alkali and evaporated to dryness, after which the dried mixture is extracted with alcohol to leave a water soluble product. The product can be used as a water reducer or superplasticizer in concrete.

Abstract: A novel catalyst has been provided for the selective hydrogenation of benzene in gasoline. The catalyst mixture comprises a water-soluble, organo-metallic, selective benzene hydrogenation catalyst comprising catalytically-active mixture of (A) M[L].sub.x [X].sub.y wherein M is a metal selected from the group consisting of Cr, Fe, Co, Ni, Mo, Ru, Rh, Pd, Ta, W, Re, Os, Ir, Pt, La and Ce; L is an aromatic hydrocarbon, e.g., benzene, diphenyl, etc., or a diaromatic hydrocarbon, e.g., naphthalene; X is a halogen; x is an integer from 1 to 10 inclusive; and y is an integer from 1 to 10 inclusive; and (B) tris(triphenylphosphine)rhodium(I)halide or tris(triphenylphosphine)ruthenium(I)halide. In use the process comprises admixing the gasoline with water. The above-identified water-soluble, organo-metallic selective benzene hydrogenation catalyst mixture is then added. A catalytic hydrogenation is then carried out in a hydrogenation zone at a temperature of about 150.degree. to about 245.degree. C. at a pressure of up to about 1000 psi in a hipbasic system of the water and the gasoline. The benzene is selectively solubilized in the water and thus is selectively hydrogenated in the presence of the above-identified water soluble organo-metallic catalyst mixture. The gasoline is then recovered from the hydrogenation zone. This combination of both catalysts was found to produce conversions in excess of 40% which was much greater than either of the catalysts separately and at the lowest effective temperature of 150.degree. C.
