Combining the performance evaluation (activity, selectivity and stability) and the characterization of the catalysts (XRD, TPD, FTIR and the pore structure measure), it can be concluded that :(1)The activity of modified β is higher than MCM-22, but the selectivity of ethylbenzene is lower about 3% than that of MCM-22;(2)The mounts of diethylbenzene and the other by-products are higher 1.7 times and 1.5 times than these of MCM-22 respectively;(3)The catalytic performance of zeolite mixture is nearly equal to modified β, but the selectivity of ethylbenzene is higher about 0.5% than that of modified β;(4)The catalytic activity of zeolite is mainly correlated with the number of acid sites, strength and distribution, and the distribution of products is determined by the binding energy of ethylbenzene and the pore structure, while the stability of catalyst is affected by the amount of poly-ring aromatic alkylate and the pore structure.

以性能评价和特性表征（XRD、TPD、FTIR和孔结构测定）相结合的方式，对上述三种催化剂性能比较的结果表明：（1）改性的活性明显高于MCM-22，但乙苯选择性却低于MCM-22绝对差约3%；（2）改性(上二乙苯和其他副产物的生成量分别约为MCM-22上对应值的1.7和1.5倍左右；（3）混合型催化剂的性能与改性相仿，但乙苯选择性提高0.5%左右；（4）对乙苯合成，沸石催化剂的活性主要取决于其B酸中心数、酸强度及酸分布，产物分布则取决于催化剂表面的乙苯脱附能垒值和孔道结构，而稠环芳烃的生成量和催化剂孔道结构是影响催化剂稳定性的主要因素。

A process for preparing alkylene glycols including reacting an alkylene oxide with water in the presence of a combination of additives and an anion exchange resin, wherein the combination of additives comprises carbon dioxide and an organic or inorganic base provided in an amount sufficient to maintain a pH of the reaction mixture between about 5.0 and 9.0, with the proviso that, when the base is bicarbonate or carbonate, then the anion exchange resin is a trimethyl benzyl ammonium anion exchange resin.

制备亚烷基二醇的方法，包括让烯化氧与水在添加剂组合和阴离子交换树脂存在下进行反应，其中添加剂组合包括二氧化碳和以足以保持反应混合物的pH值在约5.0和9.0之间的量提供的有机或无机碱，前提条件是当碱是碳酸氢盐或碳酸盐时，阴离子交换树脂是三甲基苄基铵阴离子交换树脂。

First of all crush the allspice berries and peppercorns with a pestle and mortar, then add half the chopped chilli and combine this with a dessertspoon of oil and use this mixture to coat the pieces of meat.

首先用杵和研钵将甜胡椒浆果和干胡椒捣碎，然后加入一半剁碎的红辣椒，使用一匙油将它们混合，然后将它们的混合物倒在肉片上。
