METHOD SPEEDS FCC CATALYST ATTRITION RESISTANCE DETERMINATIONS

Simon A. Weeks BP Research Centre Sunbury-On-Thames, U.K. Peter Dumbill Crosfield Catalysts Warrington, U.K. FCC catalyst attrition resistance can be determined by a method that eliminates the need for particle size measurement or accurate sampling procedures. The method, therefore, speeds attrition-resistance determinations. The method uses the industry-known jet-cup test to provide data for an attrition index WD, which is the gradient (or slope) of a plot of cumulative weight percent
