摘要： A process for preparing a transalkylation catalyst, the catalyst itself, and a transalkylation process for using the catalyst are herein disclosed. The catalyst comprises rhenium metal on a solid-acid support such as mordenite, which has been treated with a sulfur-based agent and/or a reducing agent under substantially dry reducing conditions including a temperature greater than 350°C. Such treatment reduces the amount of methane produced by metal hydrogenolysis in a transalkylation process wherein heavy aromatics like A9+ are reacted with toluene to produce xylenes. Reduced methane production relative to total light ends gas production results in lower hydrogen consumption and lower reactor exotherms.
摘要翻译：本文公开了制备烷基转移催化剂的方法，催化剂本身以及使用该催化剂的烷基转移方法。该催化剂包括在诸如丝光沸石的固体酸性载体上的铼金属，其已经在包括大于350℃的温度的基本干燥的还原条件下用硫基试剂和/或还原剂处理。这种处理减少了在烷基转移过程中通过金属氢解生产的甲烷，其中诸如A9 +的重芳烃与甲苯反应以产生二甲苯。降低甲烷生产相对于总轻馏分气体生产导致较低的氢消耗和较低的反应器放热。

摘要： A catalyst, and a process for using the catalyst, that effectively converts and transalkylates indane and C 10 and heavier polycyclic aromatics into C 8 aromatics is herein disclosed. The catalyst comprises a solid-acid support such as mordenite plus a metal component such as rhenium. The catalyst provides excellent conversion of such heavy aromatic species as naphthalene, which is also observed by a decrease in the ending-boiling-point of a hydrocarbon stream passed over the catalyst. The same catalyst is also effective for transalkylation of lighter aromatics, thus yielding a valuable xylenes product stream out of the process.

摘要： A process for isomerizing ethylbenzene into xylenes such as para-xylene using a zeolitic catalyst system based on MTW-type zeolite is disclosed. Preferably the two metals are platinum and tin. The invention obtains a stable and improved yield of xylenes such as para-xylene without excess benzene production by dealkylation. The zeolitic silica-to-alumina ratio ranges from 20 to 45. Use of MTW substantially free of mordenite improves yields and integrated aromatics complex economics by reducing undesirable aromatic ring-loss reactions.

摘要： Enabling a transalkylation process to handle both C 10 alkylaromatics and unextracted toluene permits the following improvements to be realized. No longer extracting toluene allows a reformate-splitter column to be eliminated. The extraction unit can be moved to the overhead of a benzene column. No longer requiring a rigorous split between C 9 and C 10 alkylaromatics allows a heavy aromatics column to be eliminated. Such an enabled transalkylation process requires stabilization of a transalkylation catalyst through the introduction of a metal function. A further enhancement to the flow scheme is accomplished through the elimination of clay treaters in favor of selective olefin saturation at the exits of a reforming unit and an isomerization unit. These improvements result in an aromatics complex with savings on inside battery limits curve costs and an improvement on the return on investment in such a complex.
摘要翻译：实施烷基转移方法来处理C10烷基芳族化合物和未萃取的甲苯允许实现以下改进。不再提取甲苯可以消除重整分离柱。提取单元可以移动到苯塔的塔顶。不再需要C9和C10烷基芳族化合物之间的严格拆分，可以消除重芳烃柱。这种使能的烷基转移方法需要通过引入金属官能团来稳定烷基转移催化剂。通过消除粘土处理剂有利于重整单元和异构化单元的出口处的选择性烯烃饱和来实现流程图的进一步改进。这些改进导致了芳烃复合物，节省了内部电池限制曲线成本，并改善了这种复杂的投资回报。

摘要： In processes for recovering one or more xylene isomers and isomerizing the remaining isomers for recycle, the isomerate (118) is distilled to provide a toluene-containing overhead (122), a mid-boiling fraction containing C8 aromatics (124) and a bottoms fraction containing C8 aromatics and C9+ aromatics (126). The mid-boiling fraction (124) is recycled to the unit (110) for recovering the sought xylene isomers and has sufficiently low content of C9+ aromatics that the separation feed (108) to the unit for recovering the sought xylene isomers (110) contains up to 500 ppm-mass C9+ aromatics. The processes provide a high quality xylene isomer product while achieving at least one of debottlenecking, energy savings and capital savings.
