Abstract (en)

[origin: WO9937739A1] The invention pertains to methods to process low-grade condensed fuels, primarily highly humid ones by means of pyrolysis and gasification of their organic part so as to produce liquid hydrocarbon products of pyrolysis and fuel gas, which are used for energy generation. The method can be used for environmentally friendly processing/disposal of poorly combustible wastes. The fuel is charged in a gasifier reactor type of a shaft kiln, possibly together with a solid incombustible material countercurrently to an oxygen-containing gasifying agent and combustible components of the charge are gasified. Smoke gases are introduced in the gasifying agent. The maximum temperature in the reactor is controlled within 800 to 1300 DEG C by means of variation of the fraction of the smoke gas in the gasifying agent; the oxygen content in the gasifying agent is controlled within 2 to 18 % vol.
