【Abstract】 Research on kinetics of coke burning of Pt Sn reforming catalyst and the simulation of coke burning in the radial catalyst moving bed showed that this radial bed has an inefficient zone of coke burning,the bed height needed for coke burning is not the same along radial direction and oxygen in regeneration gas can not be used efficiently.To surmount these deficiencies,two new coke burning processes with axial radial combination moving bed and two stage axial axial combination moving bed were put forward and optimal design and simulation analysis were made.According to the principles of mass and heat ransfer and kinetics of coke burning,a mathematical model for coke burning in the axial catalyst bed was established.更多还原
