Abstract

A cobalt Fischer–Tropsch synthesis catalyst supported on titania-doped silicon carbide is synthesized and comprehensively studied by a number of physicochemical means. The dynamics of the behavior and deactivation of the catalyst was studied after its stable operation for 1500 h during continuous experimental resource testing with a periodic change in the syngas flow rate and pressure and the process temperature. This catalyst has two types of active sites, on which products with different Schulz–Flory distribution parameters form. Depending on the process regime, the effective formation of soft waxes or more high-molecular-weight products is possible.

二氧化钛掺杂碳化硅支撑的钴催化剂上的费托合成

摘要

合成了负载二氧化钛掺杂的碳化硅的费托钴合成钴催化剂，并通过多种物理化学手段对其进行了综合研究。在连续实验资源测试中稳定运行1500小时后，研究了催化剂的行为和失活动力学，合成气流量，压力和过程温度会定期变化。该催化剂具有两种类型的活性部位，在其上形成具有不同舒尔茨-弗洛里分布参数的产物。取决于处理方案，可以有效地形成软蜡或更多的高分子量产物。
