    摘要: In its simplest sense, the present invention is directed toward a process for the thermal conversion of methane into unsaturated gaseous hydrocarbons, especially olefins, comprising first compressing methane in the presence of an inert gas having a higher ratio of heat capacities, Cp/Cv, than methane. The inert gas used is present in an amount sufficient to provide a compressed gas mixture having a peak temperature of adiabatic compression in the range of about 900.degree. C. to about 2200.degree. C. Under these conditions, at least some of the methane is converted to unsaturated gaseous hydrocarbons. Immediately thereafter, the compressed gas mixture is expanded, thereby substantially preventing thermal conversion of the gaseous hydrocarbons. Importantly, the compression and expansion are achieved in a single cycle of less than about one second.

    摘要: Disclosed is a method for non-catalytically reducing the amount of NO emitted from gas turbines. The method involves contacting condition effluents of the gas turbine with ammonia, replacing at least a portion of the secondary air used to dilute and cool the combustion effluents with an inert gas, such as exhaust gas from the gas turine. The temperature of the combustion effluents, the time between contacting the combustion effluents with ammonia and passage through the turbine blades, and the amount of ammonia employed is determined by the solution of the set of simultaneous equations derived from the kinetic model disclosed herein.
