Abstract
The characteristics of gas fuels for power plants produced by the partial oxidation at high pressure or by oxidative cracking at ∼750 °C of wet natural gas and associated gas are presented. The introduction of an additional stage of preliminary oxidative conversion (pre-reforming) in a flow reactor at initial oxygen concentrations of 5–8%, pressures of 25–40 bar, and temperatures of 450–600 °C or the oxidative cracking stage at atmospheric pressure and ∼750 °C makes it possible to selectively oxidize “heavy” low-octane components of complex hydrocarbon mixtures and to produce fuel gas mixtures for power plants with a high methane number and a required lower heating value. The preferable oxidation agent is atmospheric air rather than oxygen-enriched air or technical oxygen. The introduction of another additional stage of catalytic carbonylation makes it possible to synthesize a number of valuable GTL products, which can compensate expenses to costs of the proposed refinement of wet natural gas and associated gas.
