摘要：
It does exist that some of abnormal phenomena, such as cavities and particle flow variations from plug flow, are inevitable in cross-flow moving bed operations. In terms of the issues related to the abnormal operation phenomena, the experiment was conducted through a large cold model experimental facility consisting of a φ600 mm×1300 mm semi-conical and semi-cylindrical radial flow moving bed. It showed that, the critical velocity of forming cavity can be effectively increased through introducing coarse additive particles, hence the low elasticity of operation can be improved in cross-flow moving bed to some extent. Both theoretical analysis and experimental results showed that, the inhomogeneity of particle flow can be effectively improved by introducing coarse additive particles. © All Right Reserved.
