Development of tailor-made oxygen carriers and reactors for chemical looping processes at Huazhong University of Science & Technology

摘要

For the concerns of global warming, there is an urgent need of green, low-cost, and sustainable ways for the conversion and utilization of fossil energy. Holding the merit of inherent CO2 separation during carbonaceous fuel conversion, chemical looping technique is emerging as a perfect alternative to conventional fossil fuel conversion processes. Central to this technique is the design of high-performance oxygen carriers and suitable reactors that can efficiently realize the cyclic redox loop involved. To date, plenty kinds of (over 1200) oxygen carriers have been screened, synthesized and investigated by different research groups worldwide. Dozens of chemical looping reactors with thermal power ranged from kW(th) to MWth were also constructed and successfully operated. All these help to support the commercial demonstration and even industrial application of this innovative fuel conversion and carbon capture technique.
