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,N2 adsorption-desorption,XRF,TG,29Si 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.
