The Chemical-looping gasification(CLG)reaction characteristicsof pine powder with threeoxygen carriers(NiO,CuO,Fe2O3)have been finished with thermodynamic analysis and Thermo Gravimetric Analyzer(TGA)method.The results shows that the reaction activity of CuO and coke is lower than Fe2O3 and NiO in the high temperature segment(more than 600℃).The reaction activity of CuO and reducing gases,such as CO,H2and CH4,isvery good.The reaction activity of NiO and reducing gases is similar to Fe2O3,but DTG peak temperature of pine powder with NiO is lower than pine with Fe2O3 when temperature is from 600℃ to 900℃.In thermogravimetric experiment,weight change of pine powder with CuO is weaker than NiO and Fe2O3 when temperature is from 600℃ to 700℃.All results shows that the biomass CLG gasification reaction activity order is NiO>Fe2O3>CuO.
