@article { , title = {CO2 capture from fluid catalytic crackers via chemical looping combustion: Regeneration of coked catalysts with oxygen carriers}, abstract = {Oil refineries are responsible for ∼5\% of total global CO2 emissions and approximately 25–35\% of these emissions are released from a single unit called Fluid Catalytic Cracking (FCC). Chemical Looping Combustion (CLC) has been recently proposed as a novel CO2 capture method from the regenerator of FCC units as an integrated process of CLC-FCC. In this study, for the first time, the combustion behaviour of three types of cokes, a model FCC coke (which is a low volatile semi-anthracite coal), and cokes deposited on commercial FCC catalysts by n-hexadecane cracking and Vacuum Gas Oil, were comprehensively investigated with oxygen carriers (Co3O4, CuO, and Mn2O3) in a fixed-bed reactor at 700–850 °C. The results demonstrate that a high coke combustion efficiency was achieved with CuO (98 vol \%), Co3O4 (91 vol \%), and Mn2O3 (91 vol \%) at 800 °C for 30 min. CuO was the most effective oxygen carrier, at temperatures greater than 750 °C for 45 min of residence time. These are the regeneration conditions used in the conventional FCC regenerators.}, doi = {10.1016/j.joei.2023.101187}, eissn = {1746-0220}, issn = {1743-9671}, journal = {Journal of the Energy Institute}, publicationstatus = {Published}, publisher = {Elsevier BV}, url = {https://nottingham-repository.worktribe.com/output/16162172}, volume = {107}, keyword = {Chemical looping combustion, Advanced combustion, Fluid catalytic cracking, CO2 capture, Oxygen carrier}, year = {2023}, author = {Güleç, Fatih and Meredith, Will and Snape, Colin E.} }
