钴基费托合成催化剂活性及选择性影响因素分析

Analysis of the factors affecting the activity and selectivity of Co-based Fischer-Tropsch synthesis catalysts

费托合成技术是一种重要的气变液(GTL)技术,其关键是研发高活性、高选择性、性能稳定、使用寿命长的催化剂。目前应用的费托合成催化剂主要有铁基和钴基催化剂两大类。钴基催化剂因其活性高,选择性好,性能稳定,受到越来越多的关注。本文介绍了钴基催化剂的特点和发展状况,分析了影响其活性和选择性的因素。

Fischer-Tropsch synthesis is one important technology for gas to liquid （GTL）. The activity and selectivity of catalyst are key factors in this process. At present, there are mainly two kinds of catalysts, iron-based and cobalt-based, for it. The Co-based catalysts have attracted increasing attention due to their high activity, selectivity and performance stability. The characteristic and development of Co-based catalysts are reviewed, and the factors affecting the activity and selectivity of catalysts are analyzed.
