HYDROGEN-CONTAINING GAS GENERATION PROCESS Russian patent published in 2006 - IPC C01B3/38 C01B3/56 C10K3/04 

FIELD: alternate fuels.

SUBSTANCE: in order to obtain hydrogen-containing gas, reaction mixture consisting of water steam and hydrocarbons is passed through first reaction zone to form products, which are then passed through second reaction zone containing mixture of steam CO conversion catalyst and CO₂ absorbent. Reaction products formed in second reaction zone are passed through third reaction zone wherein reaction products are cooled to separate condensate from gas phase. The latter is passed through fourth reaction zone containing CO and CO₂ methanization catalyst. Hydrogen-containing gas from fourth reaction zone is recovered for further use and first to fourth stages are continuously run until level of carbon-containing compounds exceeds allowable maximum. In order to regenerate absorbent, passage of reaction products from first reaction zone to second reaction zone is cut off and the same is fulfilled with reaction products from second reaction zone passed to theirs reaction zone. Thereafter, pressure in second reaction zone is leveled with regeneration agent pressure and regeneration agent is passed through second reaction zone in direction opposite to direction in which reaction products are passed in the second stage. Once regeneration of absorbent is ended passage of regeneration agent through the second reaction zone is cut off, pressure in the second reaction space is leveled with pressure of reaction products in the second reaction zone and all stages are repeated. Hydrogen thus obtained can be used in small-size autonomous fuel processor.

EFFECT: increased economical efficiency of process.
