摘要
载氧体是化学链燃烧的关键因素之一,CuO是适合于氧气解耦化学链燃烧的载氧体之一。采用浸渍法制备了200～300μm的铜基载氧体颗粒,发现烧结会使铜基载氧体载氧量随循环次数增加而衰减。采用制备复合载氧体的疗法改善铜基的烧结问题,发现铜钴、铜镁、铜镍、铜锶四种复合载氧体可以使得载氧量稳定。
The performance of oxygen carrier is important to chemical looping combustion （CLC）. The Cu-based oxygen carrier is an alternative for chemical looping with oxygen uncoupling （CLOU） for solid fuels. Cu-based oxygen carrier of 200-300 μm was prepared by impregnation, and TGA experiment results showed that the sintering of Cu-based oxygen carrier lead to poor cyclic stability of oxygen capacity. Composite metal oxide oxygen carriers were tested to improve the sintering, and it turned out that the Cu-Co, Cu-Mg, Cu-Ni and Cu-Sr composite oxygen carriers showed excellent cyclic stability.
