Role of Texture and Acidity of SAPO-34 in Methanol to Olefins Conversion

Shamanaeva, I. A. / Yu, Zh. / Utemov, A. V. / Wu, W. / Sladkovskiy, D. A. / Parkhomchuk, E. V.

The effect of the amount of the molecular template tetraethylammonium hydroxide (TEAOH) in the precursor mixture on the physicochemical properties of SAPO-34 crystals has been examined, and the catalysts obtained have been tested in methanol conversion to lower olefins (MTO). The analysis of the textural and acidic properties of SAPO-34, which determine the high catalytic performances of catalysts in MTO, has been carried out. An effective catalyst possesses a high acidity and a developed surface with a large specific mesopore volume.
