TWO-STAGE GAS GENERATOR AND GASIFICATION METHOD WITH VERSATILITY RELATIVE TO PROCESSED RAW MATERIAL Russian patent published in 2019 - IPC C10J3/46 C10J3/48 C10J3/72 

FIELD: technological processes.

SUBSTANCE: invention relates to processes of gasification and can be used for conversion of solid or suspended raw materials, such as coal, oil coke and oil residues, into synthesis gas. Method of gasification includes (a) introduction of liquid hydrocarbon raw material and at least one of dry raw material or first suspended raw material into lower section of reactor, wherein at least one of dry raw material or first suspended raw material is introduced through two main feed nozzles, while liquid hydrocarbon raw material is introduced through at least two additional feed nozzles; (b) partial combustion of raw materials in a lower section of a reactor with a gas stream which includes oxygen-containing gas or steam to release heat and form products containing hot synthesis gas; (c) passing said hot synthesis gas from step (b) upward into upper reactor section; and (d) conducting the second suspended raw material into said reactor top section, as a result of which the heat of said hot synthesis gas maintains reaction of the second suspended feed material in pyrolysis and gasification reactions.

EFFECT: invention provides maximum efficiency of gas generator conversion.
