Title
Methanol conversion on SAPO-34 catalysts prepared by mixed template method
Abstract

Effects of templating on the catalytic performance of SAPO-34 catalyst have been investigated in conversion of methanol to olefins (MTO). SAPO-34 catalysts were synthesized using a single agent or a mixture of morpholine or tetraethyl ammonium hydroxide of (TEAOH) as the template during synthesis of gel with nominal composition as 1Al2O3:1P2O5:0.6SiO2:x morpholine:(2 − x)TEAOH:52H2O. Compared with using single template, using a mixed template leads to the particle size reduction and the morphology change to spherical type formed by the aggregation of nano-sized crystals. Although all the catalysts showed similar activity and product distribution in the MTO reaction, the catalyst obtained using the mixture of 75% morpholine and 25% TEAOH gave the longest lifetime.

When the catalysts were applied to conversion of methanol to olefins (MTO), the catalyst obtained using the mixture of 75% morpholine and 25% TEAOH gave the longest lifetime.Figure optionsDownload full-size imageDownload as PowerPoint slide
