Abstract: A method is proposed for the reduction of nitrogen oxides in a gaseous mixture containing the same, particularly in exhaust gases from internal combustion engines, to selectively form nitrogen as substantially the only nitrogen-containing product. The method comprises contacting a nitrogen-oxide containing gaseous mixture at an elevated temperature in a reducing atmosphere with a metal ruthenate.

Abstract: A process for converting benzene; an ethylenically unsaturated aliphatic hydrocarbon having from 4 to 5 carbon atoms per molecule and from 1 to 2 olefinic double bonds, and wherein said 4 carbon atom hydrocarbon is unbranched; or a monoethylenically unsaturated straight-chain aldehyde having from 4 to 5 carbon atoms per molecule and wherein the olefinic double bond is in the beta position with respect to the carbonyl group, to maleic anhydride by catalytic oxidation in the presence of a catalyst comprising a uranyl ion, especially uranium phosphate. One preferred form of the catalyst comprises an intimate chemical admixture of vanadium, uranium, phosphorus and oxygen wherein the uranium to phosphorus mole ratio is from 0.2:1 to 2:1; wherein the phosphorus to oxygen mole ratio is from 0.1:1 to 0.35:1; and wherein the vanadium to uranium atomic ratio is from 0.1:1 to 2: 1. A method of preparation of the catalyst composition is also disclosed.
