The invention pertains to methods to process combustible solid municipal wastes (SMW), 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. SMW 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 SMW are gasified. Smoke gases are introduced in the gasifying agent. The maximum temperature in the reactor is controlled within 800 to 1300 DEG C through variation of at least one of the following parameters, the mass fraction of oxygen in the gasifying agent a, and the mass fraction of incombustibles in the processed SMW b, and the mass fraction of combustibles in processed SMW c, while the ratio A = ab/c is maintained within 0.022 to 0.1. |
