Abstract

In this research, ZSM-5 zeolite with high ratio of Si to Al of 800 was synthesized to act as the catalyst for the conversion of Methanol to PROPYLENE (MTP). Instead of tetra-propyl ammonium hydroxide, here, tetra-propyl ammonium bromide which is much cheaper was used as the template. The reaction was investigated in a fixed-bed flow reactor under the operating conditions of T=460oC, P= 1 atm, and WHSV=1 h-1. The obtained results with the synthesized catalysts were compared with those of a commercial catalyst. The catalysts were characterized using XRD, SEM, TPD, BET and ICP techniques. The obtained results indicated that the SELECTIVITY of methanol conversion to light olefins, including PROPYLENE is 54%. This value is significantly higher than the 40% SELECTIVITY obtained with the commercial catalyst. Aging and deactivation after 150 hours of reactor operation was less severe for the synthesized catalyst compared to the commercial catalyst.
