METHOD OF PYROLYSIS AND GASIFICATION OF ORGANIC AGENTS OR MIXTURES OF ORGANIC AGENTS AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2006 - IPC C10G9/32 C10J3/54 C10J3/56 C10B49/16 C10B49/10 C10B49/22 C10K3/00 

FIELD: pyrolysis and gasification of solid organic agents or mixtures of organic agents.

SUBSTANCE: proposed method includes introduction of raw materials in one or several drying and pyrolysis reactors with one or several reactors with movable bed or one or several rotating reactors or one or several rotating reactors and reactors with movable bed for contact with material of fluidized combustion bed containing only ash of organic agent or unburnt carbon residues of organic agents and additional material of fluidized bed for contact with material of fluidized bed and reactor wall of fluidized combustion bed. As a result, water vapor and pyrolysis products containing condensable components and solid carbon residues are formed. Solid carbon residues or solid carbon residues and part of water vapor and pyrolysis gas with condensable components and material of fluidized bed are returned to fluidized combustion layer where carbon reside of organic components is burnt. Material of fluidized bed is heated and is again directed to pyrolysis reactor where pyrolysis residues performing function of stationary fluidized bed are burnt. After drying, water vapor and pyrolysis gases with condensable components are subjected to treatment in additional reaction zones of indirect heat exchanger at addition of vapor, oxygen and air or their mixture to pyrolysis gas or to heat exchanger in order to obtain gaseous product at high calorific power. Device proposed for realization of this method includes pyrolysis reactor, fluidized combustion bead for pyrolysis residue and reaction zone for pyrolysis gases.

EFFECT: increased calorific power.
