%X Molecular sieve Y was modified by a combination of hydrothermal treatment,dealuminization with oxalic acid,and hydrothermal crystallization in the presence of the surfactant cetyl trimethyl ammonium bromide(CTAB).The effects of CTAB amount used on the crystallinity,unit cell constant,SiO2/Al2O3 ratio,surface area and pore structure of the modified molecular sieve Y were investigated.NH3-TPD was employed to characterize the acidity.The results showed that after modification,the crystallinity and SiO2/Al2O3 r...
