METHOD FOR PRODUCTION OF SYNTHESIS GAS AND GASIFICATION REACTOR FOR ITS IMPLEMENTATION Russian patent published in 2009 - IPC C10J3/32 C10J3/40 C10J3/68 

FIELD: technological processes.

SUBSTANCE: method of synthesis gas production provides for loading of processed raw materials that contains at least hard raw materials in tank of gasification reactor and its advancement with subsequent realisation of reversed process of air and gas motion under temperature effect with formation of technological areas: areas of drying, area of pyrogenetic decomposition, areas of primary gasification of raw materials at its incomplete oxidation by air oxygen and supply of synthesis-gas with thermochemical decomposition of raw materials into inertial gas components and creation of reagent in the form of atomic carbon, area of resin thermal decomposition, area of regeneration formed by reagent laid down on fire grate during steam supply in it and production of synthesis gas at its outlet and area of synthesis gas cooling in gas duct of reactor tank, which differs by the fact that area of regeneration is formed on fire grate of reactor in the form of open natural loose cone from reagent that provides for creation of synthesis gas cleaning outside the borders of this zone, and synthesis gas cleaning area is provided with reduction of its outflow rate from regeneration area in free space of lower part of reactor tank to speed of hard particles soaring, with size of not more than 70 micron, at that under reactor cover, steam accumulation zone is created by means of processed raw material loading into reactor tank to controlled level, and from this zone steam is sucked into zone of primary gasification of raw materials with production of inertial gases and synthesis gas, and in area of reactor tank drying, raw materials dome is destroyed and evened, and in area of pyrogenetic decomposition of raw materials it is intensively loosened to provide for gas permeability and advancement from top to bottom by means of its return and direct mechanical displacement, and in area of primary gasification of raw materials, its arching is destroyed mechanically, and joint air and synthesis gas supply is implemented, and synthesis gas cooling is done down to temperature that corresponds to beginning of resin condensation, during its swirling in gas duct around reactor tank axis, at that air, steam and synthesis gas are supplied into technological areas of reactor by volume portions depending on chemical composition of raw materials.

EFFECT: creation of safe and efficient conditions for all technological processes, increased extent of produced synthesis gas cleaning.
