Abstract
A laboratory scale attrition test has been designed to simulate partic le-particle and particle-wall attrition forces which are similar to th ose experienced in commercial moving bed units. The modified drum test uses two concentric rotating drums to induce particle breakage. Using this test, the distribution of particle shapes and sizes produced by catalyst attrition in a moving bed unit have been successfully duplica ted.
