Abstract
Degradation of catalyst activity for silicoaluminophosphate catalysts is minimized for oxygenate-to-olefin reaction systems that are exposed to airborne salt concentrations above a threshold value. When airborne salt concentrations above the threshold value are detected, an air intake flow can be diverted into a cleaning flow path and/or an alternative source of regeneration media can be provided.
