Integrated CO2 capture and conversion via calcium-looping
(18-03-2021)
Chemical looping can be considered a technology platform, which refers to one common basic concept that can be used for various applications. Effective integration of CO2 capture and its conversion is an attractive strategy to reduce the CO2 emissions meanwhile achieve the potential revenue of CO2 molecule. Calcium-looping dry reforming of methane has emerged as such a promising process, implemented in a single reactor combining a CaO-based sorbent and a Ni-based catalyst, to achieve CO2 capture and in-situ conversion with CH4 into syngas. Dr. Jiawei Hua and Prof. Vladimir Galvita have been synthesize a bifunctional Ni-Ca based material, i.e. Ni and CeO2 nanoparticles co-loaded on ZrO2-coated CaCO3, which enables isothermal capture and release of CO2 at the temperature favorable for methane dry reforming, allowing to operate calcium-looping dry reforming of methane process in a single reactor by simple gas switching.
