Abstract:
1. A method of producing energy and/or synthesis gas through gasification of at least one liquid and/or solid feed in at least one chemical loop comprising at least four distinct oxidation, reduction, gasification and oxygen production reaction zones, wherein: a) oxygen is produced in an oxygen production reaction zone R b) the oxygen produced in stage a) is transported by means of the carrier gas to a gasification reaction zone R c) reduction of the oxygen carrier solid is carried out so as to release oxygen allowing to oxidize the synthesis gas, in a reduction reaction zone R d) the oxygen carrier solid that has been at least partly reduced to provide the system with oxygen is oxidized on contact with air so as to recover its maximum oxidation state, in an oxidation reaction zone R and wherein the heat provided by the reactions involved in said oxidation reaction zone R 1 and in said reduction reaction zone R 3 is used to allow energetic operation of the method.
