英文摘要	an effective route to improve the catalytic performance of sapo-34 in the methanol-to-olefin reaction by simple oxalic acid treatment was investigated. the samples were characterized by xrd, sem, n-2 adsorption-desorption, xrf, tg, si-29 mas nmr and nh3-tpd techniques. the results indicated that the external surface acidity of sapo-34 was finely tuned by oxalic acid treatment, and the selectivity to c2h4 on sapo-34 and the catalyst lifetime in the methanol-to-olefin reaction were greatly improved.
