摘要：
Small-pore molecular sieves (SAPO-34) were synthesized and characterized by X-ray diffraction (XRD), thermogravimetry differential thermal analysis (TG-DTA), temperature-programmed desorption (TPD) of ammonia and infra-red (IR) spectrometry of adsorbed pyridine, etc. The catalytic conversion of methanol to lower alkenes was investigated. The resultant H-type catalyst HSAPO-34(21) was found to be of much higher selectivity and stability than erionite (HE) and erionite offretite (HSW) zeolites. The catalyst HSAPO-34 (21) was repeatedly regenerated 55 times at 530°C and no appreciable deactivation was observed. © 1990.
