摘要: Abstract In this paper, a novel dimensionless integral form of the unreacted shrinking core model (USCM) was derived from its original one to describe redox reaction oxygen carrier (OC) particles during chemical looping (CL) processes. Four groups relevant parameters were introduced correlate solid conversion with other parameters. The analysis revealed that three are important for characterizing conversion, including Fo′, Bi′ and Rc. group has less effect on if is larger than 10. intrinsic rate exerts significant influence when Rc more sensitive while 1.The front σ related above as well. velocity (d σ/ d Fo′) obtained characterize CL
