SYNTHESIS GAS GENERATION PROCESS Russian patent published in 2008 - IPC C01B3/34 F02B43/12 

FIELD: alternate fuels.

SUBSTANCE: invention relates to technology of processing hydrocarbon stock in compression chemical reactor based on piston internal combustion engine, in particular to generation of synthesis gas via partial oxidation of hydrocarbons in rich hydrocarbon-air mixtures. Process comprises inflammation and deep oxidation of a part of hydrocarbon stock, expansion and cooling of process products when piston moves toward lower dead point, and withdrawal of products from reaction space when piston moves toward lower dead point. When piston moves toward lower dead point, volume of cylinder is filled with hydrocarbon-air mixture having air excess factor αo = 0.8-1.2 and mass mo of hydrocarbon CnHm therein. The mixture is subjected to inflammation and deep oxidation in the beginning of movement of piston to upper dead point. Later on, during further movement of piston to upper dead point, additional amount of hydrocarbon CnHm with mass md is injected to cylinder, said mass md being calculated in terms of equation md = δmo wherein δ = (αo-α)/α provided that 2n/((4n+m) = α < 3.2n/(4n+m). After that, non-catalytic carbonic-acid and steam conversion of raw material is performed resulting in generation of synthesis gas. When methane is converted, additional amount thereof md is calculated from 0.25 = α < 0.4.

EFFECT: increased yield of hydrogen in synthesis gas.
