PROCESS FOR THE THERMOCHEMICAL CONVERSION OF A CARBON-BASED FEEDSTOCK TO SYNTHESIS GAS CONTAINING PREDOMINANTLY H2 AND CO

摘要

The invention relates to a novel process for the thermochemical conversion of a carbon-based feedstock to synthesis gas containing predominantly hydrogen (H2) and carbon monoxide (CO). The process comprises (a) oxycombustion of the carbon-based feedstock to create a cogeneration of electricity and of heat; (b) high-temperature electrolysis (HTE) of water using at least the heat produced according to step (a); and (c) reverse water gas shift (RWGS) reaction starting from the carbon dioxide (CO2) produced according to step (a) and the hydrogen (H2) produced according to step (b).
