COMPARISON STUDY ON THE CATALYSIS PERFORMANCE OF MCM-49 AND B ETA ZEOLITE ON THE TRANSALKYLATION OF PIPB
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
Zeolite MCM-49 and Beta were synthesized by dynamic hydrothermal method, which were characterized by different techniques, such as XRD, SEM, N2 adsorption-desorption and NH3-TPD. The catalyst performance of MCM-49 and Beta on the transalkylation of polyisopropyl-benzene (PIPB) had been studied, comparatively. The influence factors of catalytic performance were investigated, such as reaction temperature, raw materials ratio and space velocity. Results indicate that MCM-49 shows better catalytic activity for TIPB under a relatively low reaction temperature, which should be mainly due to a large amount of structurally accessible acid sites caused by its high external surface area.
