首次以Ｈβ沸石为基础，采用一步浸渍法（Ａ）、机械研磨法（Ｂ）、沉积－沉淀法（Ｃ）及分步浸渍法（Ｄ）制备了ＳＯ－Ｆｅ２Ｏ３－Ｈβ－Ａｌ２Ｏ３催化剂，通过ＸＲＤ，ＸＰＳ，ＮＨ３－ＴＰＤ，ＦＴ－ＩＲ及化学吸附等手段对其物理化学性能进行了表征，并对其催化丙烯与异丙醇的酸化反应性能进行了评价．结果表明，在催化剂表面，ＳＯ，Ｆｅ２Ｏ３及Ｈβ沸石之间存在较强的化学作用，Ａ法和Ｃ法制备的催化剂具有明显的增强酸性；总酸量和Ｌ酸量增多，酸强度提高；该催化剂明显促进了丙烯醚化反应，其丙烯和异丙醇转化率分别由Ｈβ－Ａｌ２Ｏ３沸石的７．９８％和３５．１％提高到１４．８％和４０．０％，并发现该反应主要在Ｌ酸中心上进行．
For the first time, the catalyst of SO-Fe2O3-Hβ-Al2O3 was prepared by one-step impregnation method (A), mechanical grinding method (B), deposition- precipitation method (C) and step impregnation method (D) , XPS, NH3-TPD, FT-IR and chemical adsorption were used to characterize their physico-chemical properties. The catalytic performance of the catalysts for the acidification of propylene and isopropanol was also evaluated. The results show that there is a strong chemical interaction between SO, Fe2O3 and Hβ zeolites on the surface of the catalyst. The catalysts prepared by the methods A and C have obviously enhanced acidity; the total acidity and L acidity increase, and the acid strength increases The catalyst significantly promoted the propylene etherification reaction. The conversion of propylene and isopropanol increased from 7.98% and 35.1% of Hβ-Al2O3 zeolite to 14.8% and 40.0%, respectively. It was found that the reaction was mainly L acid center.
