MULTISTAGE SYNTHESIS GAS GENERATION PROCESS Russian patent published in 2006 - IPC C01B3/38 

FIELD: synthetic fuels.

SUBSTANCE: invention relates to a method for production of synthesis mainly containing H₂ and CO for producing hydrogen, alcohols, ammonia, dimethyl ether, and ethylene, for Fischer-Tropsch processes, and also for use in chemical industry for processing hydrocarbon gases and in chemothermal systems for accumulation and transport of energy as well as in methane-methanol thermochemical water decomposition cycles. In the multistage process of invention, at least two consecutive stages are accomplished, in each of which stream containing lower alkanes having about 1 to 34 carbon atoms are passed through heating heat-exchanger and the through adiabatic reactor filled with catalyst packing. Before first stage and between the stages, stream is mixed with water steam and/or carbon dioxide and cooled in the end of each stage. Steam leaving last stage is treated to remove water steam.

EFFECT: increased conversion of lower alkanes and reduced H₂/CO ratio in produced synthesis gas.
