    • 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.
    • 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。
