SYSTEMS, METHODS AND DEVICES FOR THE CAPTURE AND HYDROGENATION OF CARBON DIOXIDE WITH THERMOCHEMICAL CU-CL AND MG-CL-NA/K-CO2 CYCLES

摘要

Systems, methods, and devices for producing hydrogen and capturing C02 from emissions combine both H2 production and C02 capture processes in forms of thermochemical cycles to produce useful products from captured C02. The thermochemical cycles are copper-chlorine (Cu-Cl) and magnesium-chlorine-sodium / potassium cycles (Mg-CI-Na/K-C02). One system comprises a Cu-Cl cycle, a C02 capture loop, and a hydrogenation cycle. Another system comprises an Mg-CI-Na/K-C02 cycle and a hydrogenation cycle. Devices for hydrogen production, C02 capture, hydrogenation, and process and equipment integration include a two-stage fiuidized/packed bed, hybrid two-stage spray-fluidized/packed bed reactor, a two-stage wet-mode absorber, a hybrid two- stage absorber, and a catalyst packed/fluidized bed reactor.
