Description
Summary:A computational thermodynamic and experimental investigation of the characteristics of a model of a converter for producing a hydrogen-containing synthesis gas from a hydrocarbon fuel (kerosene) with its separate delivery to thermal-oxidative and steam conversions has been carried out. It is shown that the optimum conditions of converter operation correspond to the oxidant excess coefficient in the converter′s combustion chamber α > 0.5 at a temperature of the heat-transmitting wall (made from a heat-resistant KhN78T alloy (ÉI 435)) of 1200 K in the case of using a nickel corrugated tape catalyst. The content of hydrogen in the synthesis gas attains in this case 60 vol.%, and there is no release of carbon (soot) in the conversion products as well as no need for water cooling of the converter walls.
