Emissions of nitrogen oxides in exhaust from gas turbine systems are reduced, in accordance with the invention, by introducing, into the combustor, a supplementary gaseous stream comprising dihydrogen, carbon monoxide and carbon dioxide, and a stream of gaseous fuel and/or mixtures thereof, with a source of dioxygen to form a combustible gaseous mixture; combusting the mixture to produce heat and a combustion product stream; and driving a turbine with the combustion product stream to produce an exhaust stream and to generate mechanical power. Supplementary gaseous streams are, advantageously, formed by a process for hydroshifting dimethyl ether, i.e. formed by a process which comprises passing a feed stream which includes dimethyl ether and steam to a hydroshifting, reaction zone including an essentially alkali metal-free catalytic composition substantially composed of copper or nickel in elemental form. This process produces a hydroshifted product stream which is, advantageously, relatively rich in dihydrogen, carbon monoxide, and carbon dioxide.

[ We claim as our invention:] [1.] A process for abatement of nitrogen oxides in exhaust from a gas turbine system having a compressor section which receives and compresses a gaseous source of dioxygen which is directed to a combustor section from which a combustion product stream is directed to a turbine section, which process comprises:introducing, into the combustor, a supplementary gaseous stream comprising dihydrogen, carbon monoxide and/or carbon dioxide, and a stream of gaseous fuel, with the source of dioxygen to form a combustible gaseous mixture;combusting the mixture to produce heat and the combustion product stream; anddriving a turbine with the combustion product stream to produce an exhaust stream and to generate mechanical power rein the stream of gaseous fuel and the supplementary gaseous stream are mixed at ratios in a range of from about 1:19 to about 19:1 by volume measured under conditions of 25.degree. C. temperature and 1 atmosphere pressure.
