INTEGRATED OXIDATION, REDUCTION AND GASIFICATION METHOD FOR CHEMICAL LOOPING SYNGAS AND ENERGY PRODUCTION

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 affer 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 catalysed by the at least partly reduced metallic oxides from R2.
