摘要:
In a process for producing cyclohexylbenzene, benzene is contacted with hydrogen in the presence of a hydroalkylation catalyst under hydroalkylation conditions effective to form a first effluent stream comprising cyclohexylbenzene, cyclohexane, and benzene. At least a portion of the cyclohexane from the first effluent stream is then contacted with hydrogen in the presence of a dehydrogenation catalyst under dehydrogenation conditions effective to convert at least some of the cyclohexane into benzene contained in a second effluent stream. At least some of the hydrogen is supplied to the process so as to contact the dehydrogenation zone (e.g., the dehydrogenation catalyst) before contacting the hydroalkylation catalyst.
摘要(中):
在生产环己基苯的方法中,苯在氢化烷基化催化剂存在下,在有效形成包含环己基苯,环己烷和苯的第一流出物流的加氢烷基化条件下与氢气接触。 然后,在脱氢催化剂存在下,将有效将至少一些环己烷转化为第二流出物流中所含的苯的脱氢催化剂存在下,将至少一部分来自第一流出物流的环己烷与氢气接触。 在与加氢烷基化催化剂接触之前,将至少一些氢气供给到该方法中以与脱氢区(例如,脱氢催化剂)接触。
