A comprehensive,predictive two-channel model has been proposed to describe the core/annular internal recirculation flow structure in gas-solid cocurrent upflow system. The flow patternshave been determined based on minimizing the available interaction between gas and particles andthe prineiple of conservation of mass and momentum in the system.Computational results,such as those of the core region radius,voidage,gas and particlevelocities,gas and particle fluxes and their axial distributions in the core...

A comprehensive,predictive two-channel model has been proposed to describe the core/annular internal recirculation flow structure in gas-solid cocurrent upflow system. The flow patternshave been determined based on minimizing the available interaction between gas and particles andthe prineiple of conservation of mass and momentum in the system.Computational results,such as those of the core region radius,voidage,gas and particlevelocities,gas and particle fluxes and their axial distributions in the core and annular channels,arequite rational and in agreement with experimental results.The proposed model can also be used topredict the drag coefficients and backmixing in two channels,and the mass exchange between coreand annular regions.

提出了一个概念合理、预测性能好的两通道模型,描述垂直向上气固流动系统的环/核内循环流动结构。基于气固相互作用最少及质量、动量守恒原理,确定了气固两相流动状态、计算结果(如预测核心区半径、核心区及环形区内空隙率、气体速度、颗粒速度及其轴向分布等)合理,且与实验结果有良好的一致性。该模型还可以用于预测在两通道内的曳力系数,气、固返混以及两区间质量交换速率等,对反应器设计具有一定参考价值。

The intrinsic kinetics of regeneration of coked B-2 catalyst which had been runned in an industrial two-stage adiabatic beds for almost 4000 hours was determined by the internal recirculation gradientless reactor in a stream with a steam:air molar ratio of l.By means of sequential experimental design metbod,the kinetic equations were proposed as follows:For the first adiabatic bed For the second adiabatic bedBurning of coked catalyst of the first adiabatic bed was also studied for different steam to air moleratio. The result showed that steam made the burning rate slow and gave a smooth regeneration.
