CRYSTALLINE MICROPOROUS SILICOALUMOPHOSPHATES, METHOD OF THEIR PRODUCING AND UTILIZATION

摘要

FIELD: chemical technology. SUBSTANCE: invention relates with the producing silicoalumophosphate catalysts for conversion of methanol to the light olefins - ethylene and propylene (MTO reaction). Method of synthesis proposed can be used for the control of silicoalumophosphate chemical composition, especially, with regard to silicon content. In part, it was found that synthesized catalysts could show enhanced stability to "coking" deactivation. The latter property is very important for development of MTO processes based on the synthesized silicoalumophosphates. EFFECT: improved method of catalyst producing.
