METHOD AND DEVICE FOR OBTAINING ALCOHOLS Russian patent published in 2016 - IPC C12P7/06 C12P7/16 C12M1/107 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to field of chemistry. Claimed are: method for obtaining C₂-C₆alcohols from methane-containing raw material, equipment for obtaining C₂-C₆alcohols and method for obtaining fuel for motorised transport. Method for obtaining C₂-C₆alcohols includes reforming of methane-containing raw material in first reformer with obtaining first product flow, including CO, H₂ and CO₂, reforming of part of first product flow and/or part of methane-containing raw material in second reformer in presence of steam and oxygen with obtaining second product flow, including CO, H₂ and CO₂, bacterial fermentation with application of acetogenic anaerobic bacteria of first and second product flows with obtaining third product flow, which includes water solution of C₂-C₆alcohol, nutrients and intermediate reaction products, as well as fourth product flow, including CO, H₂ and CO₂, return of part of fourth product flow in methane-containing raw material and separation of part of C₂-C₆alcohol from third product flow with obtaining fifth product flow and cooling part of fifth product flow, return of part of cooled fifth product flow into fermenter. Method for fuel obtaining includes realisation of stages of natural gas reforming and fermentation with obtaining product, including C₂-C₆alcohol, separation of part of one C₂-C₆alcohol, drying separated C₂-C₆alcohol.

EFFECT: inventions provide high degree of carbon monoxide conversion, effective obtaining of synthesis-gas with further fermentation.
