英文摘要: HY zeolite was modified by chemical liquid deposition with i-C(4)H(9)Si(OC(2)H(5))(3) and a hydrothermal treatment. The samples were characterized by X-ray diffraction. N(2) adsorption, and pulse mass analysis to investigate the influence of modification on the framework structure, specific surface area, pore diameter, and adsorption behavior. The catalytic activity of HY zeolite and modified HY in the alkylation of naphthalene with tert-butyl alcohol was evaluated. The modification of HY zeolite did not change the framework structure but increased the specific surface area, decreased the pore diameter, and narrowed the pore opening. The catalytic activity of the modified HY zeolite catalyst for tert-butylation of naphthalene was decreased while the shape-selectivity for 2,6-di-tert-butylnaphthalene (2,6-DTBN) was clearly increased, and a high 2,6-DTBN/2,7-DTBN ratio of 6.62 was obtained.
