研究了钴/锰氧化物催化剂在固定床反应器中一氧化碳与氢在有利于生成气态、液态和固态(即石蜡)烃的条件下的性能。采用共沉淀法制备了直径为3 mm的挤出物状钴/锰氧化物催化剂。固定床反应器由一根直径为21 mm的单管组成，类似于典型工业规模的费托反应器中使用的管子。该催化剂需要相当长的稳定期，并产生了工业上可行的产品谱。观察到了显著的水气活性，这在费托合成条件下通常不是钴基催化剂所能预期的。当压力升高到2100kPa时，水-气变换反应受到抑制，烯烃产率降低。
An investigation was undertaken to establish the performance of a cobalt/manganese oxide catalyst in a fixed bed reactor for the conversion of carbon monoxide with hydrogen under conditions favouring the formation of gaseous, liquid and solid (i.e. wax) hydrocarbons. The cobalt/manganese oxide catalyst in the form of extrudates with a diameter of 3mm was prepared by a co-precipitation method. The fixed bed reactor consisted of a single tube with a diameter of 21mm, similar to tubes used in typical industrial scale Fischer–Tropsch reactors. The catalyst requires a fairly long stabilisation period and produced an industrially viable product spectrum. Significant water–gas activity was observed which is not normally expected for cobalt based catalysts under Fischer–Tropsch synthesis conditions. Increased pressure up to 2100kPa suppressed the water–gas shift reaction and lowered the olefin production.
