Integrated oxidation, reduction and gasification for the production of synthesis gas and power chemical looping process

摘要

Method of production of synthesis gas in at least one chemical loop comprising at least three distinct reaction zones of oxidation, reduction and gasification, in which: 1. oxidation of the metal oxides reduced MeO1-x is performed in an area oxidation reaction R1 supplied with air; 2. combusting a hydrocarbon feed solid and / or liquid and / or gas is effected by at least partial reduction of the metal oxides MeO in a reaction zone to produce reduction R2 a gaseous mixture of CO2 / H2O; 3. catalytic gasification of a solid hydrocarbon feed and / or liquid is effected by means of at least partially reduced metal oxides from R2 in a reaction zone R3 gasification to produce a synthesis gas CO + H2; and in which the energy released by the oxidation of the metal oxides in the oxidation reaction R1 allows activation of the gasification reactions and reduction.
