  A process for producing an ethylbenzene product having a purity of at least 99.50 percent based on the weight of ethylbenzene present in the product by the ethylation of the benzene present in non-extracted feed, e.g., non-extracted hydrocarbon composition. The non-extracted feed is substantially free of both C 4 − hydrocarbons and the C 7 + aromatic hydrocarbons and contains benzene and benzene coboilers. The process is carried out in the liquid phase, in the presence of an acid-active catalyst containing MCM-22 family molecular sieve, and under specified conditions.

• Insights into the Major Reaction Pathways of Vapor-Phase Hydrodeoxygenation of<i>m</i>-Cresol on a Pt/HBeta Catalyst

  Conversion of m‐cresol was studied on a Pt/HBeta catalyst at 225–350 °C and ambient hydrogen pressure. At 250 °C, the reaction proceeds through two major reaction pathways: (1) direct deoxygenation to toluene (DDO path); (2) hydrogenation of m‐cresol to methylcyclohexanone and methylcyclohexanol on Pt, followed by fast dehydration on Brønsted acid sites (BAS) to methylcyclohexene, which is either hydrogenated

  转化米甲酚在225-350℃和环境氢气压力研究了在Pt / HBeta催化剂。在250°C下，反应通过两个主要反应途径进行：（1）直接脱氧为甲苯（DDO途径）；（2）氢化米甲酚到甲基环己酮和甲基环己醇在Pt，然后在布朗斯台德酸位点（BAS）到甲基环己烯，其是氢化到甲基环己烷在Pt或环收缩到BAS dimethylcyclopentanes和乙基环戊烷快速脱水（HYD路径）。初始氢化是HYD路径的速率决定步骤，因为其速率明显低于后续步骤。DDO路径的表观活化能为49.7 kJ mol -1但对于HYD路径，活化能为负。因此，较高的温度导致DDO路径成为对甲苯的主导路径，而路径HYD，随后快速平衡到甲苯，小于占优势，由于初始氢化的抑制米甲酚。

  The contact reactions of 2-methyl[2-13C]hexane and 2-methyl[6-13C]hexane have been investigated at 270 and 360°C, respectively, over a 10% Pt–Al2O3 catalyst. The isomerizations of 2-methylhexane and 2,3-dimethylpentane, at 270°C, are very similar: the orders as a function of hydrogen are positive (0.2–1.75) and all the products are obtained by a one-step process according to either a bond-shift or

  2-甲基[2-的接触反应13 C]己烷和2-甲基[6- 13 C]己烷已经在270和360℃分别研究，超过10％的Pt-Al 2 ö 3催化剂。2-甲基己烷和2,3-二甲基戊烷在270°C下的异构化非常相似：作为氢的函数的阶数为正（0.2-1.75），所有产物均通过一步法根据要么是键移机制，要么是循环机制（后者是主要机制）。假设碳氢化合物吸附在几个连续的金属位点上，则正序以及不存在加扰的情况与Frennet模型一致。
