METHOD FOR THERMOCHEMICALLY CONVERTING A CARBONACEOUS FEEDSTOCK INTO SYNTHESIS GAS CONTAINING MAINLY H2 AND CO

摘要

The present invention concerns a method for thermochemically converting a carbonaceous feedstock into synthesis gas containing mainly hydrogen (H2) and carbon monoxide (CO), comprising the following steps: a/ oxy-combustion of the carbonaceous feedstock in order to cause the cogeneration of electricity and heat; b/ simultaneous electrolysis of water and carbon dioxide (CO2) at a high temperature (EHT), referred to as co-electrolysis, from at least the heat produced in step a/ and at least the carbon dioxide (CO2) produced in step a/.
