SYNTHESIS GAS PRODUCING METHOD AND DEVICE Russian patent published in 2008 - IPC C01B3/38 

FIELD: gas.

SUBSTANCE: synthesis gas producing method includes partial oxidation of the first portion of hydrocarbon in partial oxidation reactor, wherein the first flow leaving the reactor is obtained, cooled up to the temperature of 650° to 1000°C, and supplied to the reforming heat-exchanger. Then the second portion of hydrocarbon with steam passes through catalyst space in the reforming heat-exchanger, and the second flow leaving the reactor is generated, discharged from catalyst space, and mixed with the first flow leaving the reactor. Mixture passes through catalyst space in indirect heat exchange therewith, and mixture is cooled and catalyst space is heated, and after that the cooled mixture is taken from the reforming heat-exchanger. Modernising procedure of synthesis gas producing method includes partial oxidation reaction stage, whereat the first hydrocarbon flow is turned into the first flow leaving the reactor, heat recovery stage, whereat the first flow leaving the reactor is cooled, and steam is generated with the help of recovered heat, and outlet flow treatment stage, at which cooled flow leaving the reactor is received, and synthesis gas is produced with increased hydrogen content. It also includes the cooling stage of the first flow leaving the reactor up to the temperature of 650° to 1000°C, the stage at which the first cooled flow leaving the reactor is discharged into the reforming heat-exchanger, stage at which the second portion of hydrocarbon with steam passes through catalyst space in the reforming heat-exchanger, and the second flow leaving the reactor is generated, stage at which the second flow leaving the reactor is discharged from catalyst space and mixes with the first flow leaving the reactor, stage at which mixture passes through catalyst space in indirect heat exchange therewith, and mixture is cooled and catalyst space is heated, and stage at which cooled mixture is supplied from the reforming heat-exchanger to heat recovering stage.

EFFECT: allow to increase in capacity as to hydrogen.
