Реферат:
Cobalt-alumina Fischer-Tropsch catalysts prepared by DPU (deposition by precipitation during urea decomposition) method are highly active and have good C5+ selectivity. However the activation temperature is high for these catalysts exceeding 500oC, which makes the activation procedure and equipment expensive. Introduction of tiny amount of noble metal facilitates cobalt reduction and decreases the required activation temperature. By this poster presentation we report the effect of ruthenium content on reduction behavior and kinetic parameters of Ru-promoted Co-Al catalyst as well as the catalytic activity and selectivity these catalysts in the Fischer-Tropsch synthesis. Addition of small amounts of Ru to alumina-supported cobalt catalysts significantly lowers the temperature of cobalt reduction. The promoted catalysts exhibit high catalytic activity and selectivity in the Fischer-Tropsch synthesis, which is comparable with unpromoted catalyst.
