METHOD OF ENERGY UTILIZATION OF SOLID CARBON-CONTAINING WASTES AND THE SMALL MOBILE SOLID FUEL ELECTRIC HYDROGEN DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC F23G5/27 C10J3/00 C10B49/00 

FIELD: electric power industry; hydrogen energy.

SUBSTANCE: small distributed electric power industry, including hydrogen energy, based on renewable energy resources. Method of energy utilization of solid low-grade substandard carbon-containing raw materials, such as production and consumption waste, as well as peat, brown coal and products of their processing, according to a multi-stage technological scheme, contains 4 stages: fuel preparation, gasification, power generation and hydrogen generation. At the first stage - fuel preparation - preliminary preparation of raw materials, which are multicomponent mixed wastes, is sequentially performed, including collection, sorting, separation, disassembly with separation into material and energy raw materials and storage or accumulation, mechanical preparation, including crushing, grinding, compaction and conditioning, including mixing, composition optimization, drying, heating of energy raw materials. At the second stage - gasification - thermochemical conversion is carried out - steam-air gasification in a dense layer of prepared conditioned solid fuel in compact cylindrical inclined rotating gasifier reactors with a steam-water cooling jacket, with the supply of gasifying agents - oxygen with air and water or steam into the reaction zone of the gasifier rectors in a stoichiometric ratio to the fuel to be gasified, to obtain a combustible fuel gas containing carbon monoxide and hydrogen. At the third stage - power generation - the resulting gas is used in power plants - gas piston engine-generators for production of electricity. The fourth stage is hydrogen generation, in which hydrogen is produced by electrolysis of water using electricity obtained in the third stage, with the accumulation of the resulting hydrogen and the supply of the resulting oxygen to enrich/replace the air supplied to the reaction zone of the gasifier reactors in the second stage. At the same time, produced hydrogen is supplied to external consumers and used to refuel the fuel elements of the units, and also the possibility of transporting the types of material raw materials and gasification waste separated at the first stage for disposal at the second stage.

EFFECT: increased productivity of gasification, increased compactness, mobility and availability while reducing the specific weight per unit of power, ensuring the continuity of autonomous operation, developing the infrastructure of hydrogen energy.
