Abstract
This study concerns about catalyic cracking of iso-octane over cation (Cd2+, Ca2+ and La3+) exchange mordenites. It deals with mordenite shape selectivity and with kinetics of this catalytic reaction. The striking feature was that over the region of cracking temperature investigated, 523-665K, the yield of isobutene was predominant, relative to that of larger or smaller carbon chain(s). This permits kinetic analysis of the heterogeneous catalytic system in terms of the modified pulseversion microcatalytic chromatography. The observed activation energy (Ea, KJ mol-1) was found to be 46 for Cd-M, 57 for Ca-M and 59 for La-M, respectively.
