Methanol to lower olefins conversion in a slurry reactor: Effects of acidity and crystal size of silicoaluminophosphate catalysts

Konnov, S. V. / Pavlov, V. S. / Ivanova, I. I. / Khadzhiev, S. N.

Abstract Effects of the crystal size and acidity of silicoaluminophosphates on their catalytic behavior in the methanol to lower olefins conversion in a slurry reactor have been studied. It has been found that an increase in the crystal size of silicoaluminophosphate causes a reduction in its catalytic activity, which is due to an increase in diffusion limitations for both reagents and reaction products. An increase in the number of acid sites and their localization on the outer catalyst layer improve the time stability of silicoaluminophosphate performance and the selectivity of methanol conversion to lower olefins.
