Abstract

This disclosure relates to methods for reducing CO2 emissions from a fluid catalytic cracking process by providing a chemical looping system comprising a regenerator and reducer reactor, an oxidizer reactor, and a combustor reactor, and by sequestering the carbon dioxide of a CO2 and H2O stream. Also, this disclosure relates to methods for reducing CO2 emissions from a fluid catalytic cracking process by partially oxidizing catalyst coke particles in a fluid catalytic cracking regenerator reactor to produce synthesis gas, and by providing a chemical looping system comprising a reducer reactor, an oxidizer reactor, and a combustor reactor.
