二甲苯异构化催化剂的表面酸性及其催化活性
The results indicate that Cs is located at the area between Ag and α-Al2O3. Cs can improve the selectivity through adjusting the electronic properties on the surface of catalysts, inhibiting the absorbing of ethylene oxide, combustion, and isomerization.
结果表明，对于新催化剂来说，Cs位于Ag与α-Al2O3载体之间。Cs通过调节催化剂表面的电子性能、抑制环氧乙烷在催化剂表面的吸附、燃烧和异构化来提高选择性。
The m-diethylbenzene is produced mainly on the internal surface acid site, but not by isomerization of p-diethylbenzene on the external surface. Phosphorus mainly modified surface acid site of zeolites.
间二乙苯主要在内表面酸中心上生成，而对二乙苯在外表面酸位上异构化不是主要途径.不同的磷加入量对分子筛表面磷的状态产生不同的影响。
The composite solid oxide super acid Pt-SO_4~ ( 2-)/ ZrO_2-Al_2O_3 catalyst was prepared, and its structure, surface properties and catalytic activities for n-butane isomerization reaction were investiga-ted by XRD, XPS, SEM, FT-IR.
制备了复合氧化物固体超强酸催化剂Pt-SO4~（2-）/ZrO2-Al2O3，通过XRD、XPS、SEM、FT-IR等手段研究了其结构、表面性质及其对正丁烷异构化反应的催化活性。
