attrition tolerance is a key factor for fluidized reactor. you could improve its strength by adding strcuture promotor, for example Al2O3. however, adding large amount of such strcture promotors would result in the change of porosity and interactions. so a catalyst with high activty do not means it is a good catalyst.
