Abstract
The study on influence of initial SiO2/Al2O3 ratio and approaches to precursor mixing (conventional mixing with magnetic stirrer and overhead mixing with ultrasonication (US)) on phase, texture and acidity of SAPO-34 and catalytic performance in methanol-to-olefin (MTO) process is presented. Contribution of the amorphous phase in the catalysts were determined using neural network via counting cubic (crystalline) and spherical (amorphous) particles in SEM images. We have found out that ultrasonication pre-treatment improves the crystallinity of SAPO-34 crystals and facilitates silicon incorporation into AlPO framework at higher SiO2/Al2O3 ratio. Acidity of samples synthesized with US pre-treatment is increased comparing with corresponding samples synthesized without US pre-treatment. US-treated catalyst lifetime is also enhanced. As a result, total olefin yield is higher on US-treated catalysts comparing with corresponding SiO2/Al2O3 ratio of non-treated ones.
