%X Recent progress of the study on fluidic catalyst attrition mechanism and attrition test methodology was reviewed. Nanoindentation and PSD test were used to examine influences of various mechanical and hydrodynamical parameters upon attrition modes of catalyst particles dominated by fragmentation and abrasion. Prevailing lab-scale attrition assessment methods were introduced, and fluidized-bed jet attrition tests were found to be effective and straightforward to predict catalyst attrition. For further exploration of attrition mechanisms of fluidic catalyst and improvement of attrition test, in-depth study work will be needed on aspects such as hydrodynamic models, computing simulation and microscopic mechanic test in the future.
