METHOD OF PRODUCING SYNTHESIS GAS BY INCOMPLETE OXIDATION OF COMBUSTIBLE GAS AND REACTOR FOR ITS IMPLEMENTATION Russian patent published in 2025 - IPC C01B3/36 B01J8/06 B01J19/28 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing synthesis gas by incomplete oxidation of combustible gas in a reactor equipped with a rotary regenerative tubular heat exchanger, which includes heating to a high temperature of at least a portion of the heat-insulated reaction chamber of the reactor; feeding into the reactor two reagent gases – a combustible gas and an oxygen-containing oxidant gas in an amount which is insufficient for complete oxidation of the combustible gas; mixing the combustible gas and the oxidant gas in the reaction chamber of the reactor; reaction of combustible gas and oxygen-containing gas; removing a stream of gaseous products in the form of synthesis gas from the reactor. Process is carried out by feeding combustible gas through channels-pipes of a regenerative tubular heat exchanger, which are located in the section of the gas duct for supplying the combustible gas, and the oxidant gas through the channels-pipes of the regenerative tubular heat exchanger, which are located in the section of the gas duct for supplying the oxidizer gas, wherein the combustible gas and oxidizer gas flows each flow in its part of the tubular heat exchanger in one direction, are heated during heat exchange with the pipe material and then enter the reaction chamber, and the stream of hot gaseous products is discharged from the chamber through the channels-pipes of the regenerative tubular heat exchanger, which are located in the cross-section of the gaseous products discharge duct in the direction opposite to the direction of the flow of the combustible gas, wherein channels-tubes heated during heat exchange with flow of hot gaseous products are displaced into flows of combustible gas and gas-oxidizer, while channels-tubes cooled in flows of combustible gas and gas-oxidizer are displaced into flow of gaseous products. Invention also relates to a reactor for producing synthesis gas.

EFFECT: high energy efficiency and continuous conversion of combustible gas into synthesis gas.
