INTEGRATED OXIDATION, REDUCTION AND GASIFICATION PROCESS FOR THE PRODUCTION OF CHEMICAL LOOP SYNTHESIS GAS

摘要

The invention relates to an energetically self-sufficient syngas production method in at least one chemical loop. The chemical loop involves at least three distinct oxidation, reduction and gasification reaction zones: 1. at least one air-supplied oxidation reaction zone R1, referred to as air reactor, where the reaction of oxidation of the metallic oxides takes place after reduction, 2. at least one combustion reduction reaction zone R2, referred to as fuel reactor, where the feed combustion reaction takes place in the presence of the oxygen present in the metallic oxides, 3. at least one gasification reaction zone R3, referred to as gasification reactor, for gasification of the solid and/or liquid feeds in order to produce a syngas, said gasification being catalyzed by the at least partly reduced metallic oxides from R2.
