“潜芳烃”集总动力学模型评价重整催化剂

A KINETIC MODEL WITH THE CONCEPT OF“POTENTIAL AROMATICS”FOR EVALUATING REFORMING CATALYSTS

本文提出利用“潜芳烃”概念建立重整反应潜芳烃集总动力学模型,用于快速评价及筛选催化剂;文中建议将长周期运转与催速老化法结合起来,在按“潜芳烃”集总动力学方法基础上评价催化剂,可以得到与传统方法一致的结果,而且可以获得较多的评价催化剂性能的信息。这是一种值得重视的方法。

A kinetic model for naphtha reforming based on the concept of 'poten- tial aromatics' in naphtha has been proposed for the use in rapid screening and evaluating re- forming catalyst. It is suggested that the method of evaluation of reforming catalyst should be established in combination with the long-term running method and the accelerated aging method for traditional evaluation of reforming catalysts. The primary data indicate that it is a good way for getting more information on catalyst behaviour and the results agree well with the traditional methods.
