Abstract
A system integrating heavy fuel coking and chemical looping combustion is provided. The system includes a source of heavy fuel, a cracking reactor into which the fuel and metal oxides are introduced, a fuel reactor in fluid communication with the cracking reactor, and an air reactor in fluid communication with the fuel reactor. In the cracking reactor, the fuel undergoes a cracking reaction forming products and petcoke deposits on the metal oxides. The fuel reactor is configured to gasify metal oxides with petcoke deposits to produce syngas and reduce the metal oxides. The system transports a first portion of the reduced metal oxides to the cracking reactor and a second portion to the fuel reactor. The air reactor is configured to receive reduced metal oxides from the fuel reactor and oxidize them. The system is further configured to transport the oxidized metal oxides to the fuel reactor.
