Abstract

The invention refers to a process to produce H2 from biomass containing carbon. The biomass is gasified to obtain a gaseous flow essentially containing molecules of carbon monoxide (CO) and molecules of molecular hydrogen (H2). These molecules (CO) and (H2) are then oxidized by oxygen holders in oxidized state (MeO) to obtain a gaseous flow essentially containing CO2 and water steam (H2Osteam) and oxygen holders in reduced state (Me). The oxygen holders are then oxidized by water steam. That oxidation produces oxidized oxygen holders and a gaseous flow essentially containing di-hydrogen (H2). The invention also refers to a system containing the means to perform the steps of such a process.
