【 摘 要 】

A series of Co/TiO₂ catalysts was tested in a parameters field study for Fischer‒Tropsch synthesis (FTS). All catalysts were prepared by the conventional impregnation technique to obtain an industrially relevant Co content of 10 wt % or 20 wt %, respectively. In summary, 10 different TiO₂ of pure anatase phase, pure rutile phase, as well as mixed rutile and anatase phase were used as supports. Performance tests were conducted with a 32-fold high-throughput setup for accelerated catalyst benchmarking; thus, 48 experiments were completed within five weeks in a relevant operation parameters field (170 °C to 233.5 °C, H₂/CO ratio 1 to 2.5, and 20 bar(g)). The most promising catalyst showed a CH₄ selectivity of 5.3% at a relevant CO conversion of 60% and a C₅₊ productivity of 2.1 g_C5+/(g_Co h) at 207.5 °C. These TiO₂-based materials were clearly differentiated with respect to the application as supports in Co-catalyzed FTS catalysis. The most prospective candidates are available for further FTS optimization at a commercial scale.
