Effect of La Promotion on Co/ZrO₂ Catalysts in Fischer-Tropsch Synthesis

Abstract:

The effects of lanthanum promotion on cobalt based catalysts in Fischer-Tropsch synthesis were investigated. The Co/ZrO₂ catalysts promoted by lanthanum had higher activity and selectivity in Fischer-Tropsch synthesis. The catalyst with the La content 1% had the highest activity and selectivity attributed to the promotion effect of La. However, excessive La addition could depress the activity of the catalyst due to the Co-La interaction and the lower reduction degree.
