Patent ID: 8916128

Claim:
A method of producing syngas in at least one chemical loop comprising at least three distinct oxidation, reduction, gasification reaction zones, comprising: 1) carrying out oxidation of reduced metallic oxides in an air-supplied oxidation reaction zone R 1 ; 2) carrying out combustion of a solid and/or liquid hydrocarbon feed through at least partial reduction of metallic oxides in a reduction reaction zone R 2 so as to produce a gaseous CO 2 /H 2 O mixture; 3) supplying a gasification reaction zone R 3 through a line with at least part of the CO 2 /H 2 O mixture coming from reaction zone R 2 , and sending the remaining part of the CO/H 2 O mixture through another line to a condenser in order to separate the CO 2 from H 2 O; and 4) carrying out catalytic gasification of a solid and/or liquid hydrocarbon feed by means of the at least partly reduced metallic oxides from R 2 in the gasification reaction zone R 3 so as to produce a CO+H 2 syngas, wherein a fraction of the total capacity of transfer of the oxygen remaining in the at least partly reduced metallic oxides from R 2 is from 0 to 0.5; wherein the energy released through oxidation of the metallic oxides in oxidation reaction zone R 1 allows the gasification and reduction reactions to be activated.
