Study of cracking of large molecules over a novel mesoporous beta

Abstract A novel mesoporous beta with interconnected macropores and skeletons under hydrothermal conditions was prepared through zeolite degraded method. The skeletons can be templated to the morphology of network in different conditions. The physical properties of the mesoporous beta were characterized by XRD, SEM and nitrogen sorption techniques. Catalytic tests show that the mesoporous beta catalyst exhibits high catalytic activity compared with the conventional microporous beta zeolites for catalytic cracking of 1,3,5-triisopropylbenzene. The high 1,3,5-triisopropylbenzene conversion are mainly assigned to the presence of the hierarchical porosity of the pore walls.
