Abstract

Results from the prolonged tests of zeolite-containing cobalt catalysts for Fischer–Tropsch synthesis in reactor tubes comparable in size to those used in industrial reactors. During 3000 hours on stream catalyst activity was decreased by 13%. It is shown that the main reasons for zeolite-containing cobalt catalyst deactivation are agglomeration of cobalt clusters and carbon deposition on the catalyst surface. The authors propose one method of reducing the catalyst deactivation rate and two methods of regenerating it. It is shown that the oxidative regeneration treatment of zeolite-containing cobalt catalysts allows to recover 98% of the initial activity.

费托合成反应器中含沸石钴催化剂的失活和再生

摘要

对用于费托合成的含沸石钴催化剂在尺寸与工业反应器相当的反应器管中进行长期测试的结果。在运行 3000 小时期间，催化剂活性下降了 13%。结果表明，钴簇团聚和催化剂表面积碳是导致含沸石钴催化剂失活的主要原因。作者提出了一种降低催化剂失活率的方法和两种再生催化剂的方法。结果表明，含沸石钴催化剂的氧化再生处理可以恢复98%的初始活性。
