The chabazite-like silicoaluminophosphate molecular sieve SAPO-34 was synthesized using
diethylamine and morpholine as templates, and the effect of using the mixture of these two
templates were investigated in detail. Synthesis gel was treated by ultrasonic waves before
hydrothermal treatment for all samples. XRD, SEM and FTIR were used to characterize the
zeolites. During methanol to olefin reaction, the catalytic performance of these samples was
conducted in a micro reactor in the temperature range of 300-500℃. Test results indicated that the
light olefins (C2
=+C3
=) selectivity is about 90% in MTO reaction on these samples, and the
methanol conversion is about 100% at 400℃. Propylene decreased with temperature increase,
regularly.
