    • There is provided a process for ring opening of aromatics or cycloaliphatics, as well as isomerization of aliphatics. The feedstream to this process comprises hydrocarbons having 6 carbon atoms. The process involves the use of a recycle stream containing a source of chlorine, such as carbon tetrachloride, and this process involves the use of at least two reactors connected in series. The first reactor comprises a ring opening catalyst and is operated under conditions which particularly promote ring opening. The catalyst in this first reactor may comprise zirconia modified with tungstate and platinum. A second, downstream reactor is operated under conditions to promote isomerization of aliphatics. The catalyst in the second reactor may comprise alumina, platinum and a chloride component. The catalysts in both the first and second reactors are chlorine resistant.
    • 提供了芳族化合物或环烯烃的开环方法以及脂肪族异构化方法。 该方法的进料流包含具有6个碳原子的烃。 该方法包括使用含有氯源的再循环流,例如四氯化碳,并且该方法涉及使用串联连接的至少两个反应器。 第一反应器包括开环催化剂,并在特别促进开环的条件下操作。 该第一反应器中的催化剂可以包括用钨酸盐和铂改性的氧化锆。 第二个下游反应器在促进脂肪族异构化的条件下运行。 第二反应器中的催化剂可以包括氧化铝,铂和氯化物组分。 第一和第二反应器中的催化剂都是耐氯的。
