摘要： A process for the disproportionation of a toluene containing feedstock employing a nickel modified mordcnite catalyst comprising particulate mordenite having nickel dispersed throughout the catalyst particles to provide surface nickel and interior nickel within the mordenite crystal structure. The catalyst is pretreated Io selectively deactivate the surface nickel to provide a surface nickel content of reduced catalytic activity. The interior nickel lhus has a higher catalytic activity than the surface nickel. The feedstock is supplied to a reaction zone containing the catalyst to cause disproportionation of toluene in the feedstock to produce a mixture of benzene and xylene. The non-aromatic content of the product is less than the non-aromatic content of a corresponding disproportionation product which would be produced by the disproportionation of the fecdstream in the presence of a corresponding nickel mordenite catalyst which has not been pretreated.
摘要翻译：含有甲苯的原料的歧化的方法，该方法使用镍改性的莫氏体催化剂，其包含分散在整个催化剂颗粒中的镍的颗粒丝光沸石，以在丝光沸石晶体结构内提供表面镍和内部镍。预催化剂催化剂选择性地使表面镍失活以提供具有降低的催化活性的表面镍含量。内部镍镉具有比表面镍更高的催化活性。将原料供给到含有催化剂的反应区，以使原料中的甲苯发生歧化，产生苯和二甲苯的混合物。产物的非芳香族含量小于相应的歧化产物的非芳香族含量，其将通过在未进行预处理的相应的镍丝光沸石催化剂的存在下通过歧管进行产生。

摘要： A process for the disproportionation of toluene over a nickel-modified mordenite catalyst which has been pretreated with mild sulfiding procedure. The sulfur dose is employed in a minor amount relative to the nickel content of the catalyst. The modified mordenite catalyst is contacted with a sulfur-containing compound such as hydrogen sulfide or dimethyldisulfide (DMDS) under pretreatment conditions involving a temperature of at least 100°C. The sulfur-containing compound is employed in a relatively small amount to passivate only a minor portion of the active nickel sites. A toluene-containing feedstock is brought into contact with the pretreated catalyst under conditions effective for the disproportionation of toluene and a disproportionation product is removed from contact with the catalyst. The mordenite catalyst contains nickel in an amount within the range of 0.1-2 wt.%. The catalyst may contain another metal such as palladium or platinum, or a lanthanide series metal such as lanthanum or cerium. Pretreatment of the catalyst may be carried out by flowing a fluid pretreatment stream having a sulfur component into contact with the catalyst. The pretreatment stream comprises hydrogen sulfide or a thio compound which is converted to hydrogen sulfide under the pretreatment conditions.

摘要： A process for making styrene including reacting toluene with a C1 source in the presence of a catalyst and a co-feed including at least one oxidizing agent in a reactor to form a product stream including ethylbenzene and styrene and, optionally, at least one de-oxidized oxidizing agent. The C1 source toluene is reacted with one or more of methanol, formaldehyde, formalin, trioxane, methylformcel, paraformaldehyde, and methylal. The co-feed includes an oxidizing agent selected from the group of oxygen, air, nitrobenzene, quinones, anthracene, nitrous oxide, and combinations thereof. The co-feed may be combined with nitrogen prior to combining the co- feed with the reactants. The co-feed may be combined with the reactants in any desired amounts. In an embodiment, the process of the present invention contains a reactant:co-feed molar ratio of at least 1:1.

摘要： Alkylation systems and methods of minimizing alkylation catalyst regeneration are described herein. The alkylation systems generally include a preliminary alkylation system adapted to receive an input stream including an alkyl aromatic hydrocarbon and contact the input stream with a preliminary alkylation catalyst disposed therein to form a first output stream. The preliminary alkylation catalyst generally includes a zeolite catalyst having a SiO 2 /Al 2 O 3 ratio of less than about 25. The alkylation systems further include a first alkylation system adapted to receive the first output stream and contact the first output stream with a first alkylation catalyst disposed therein and an alkylating agent to form a second output stream.
