- W2356489659 abstract "The effects of the surface characteristics of different activated carbons on the catalytic activities of ruthenium catalysts for ammonia synthesis were studied. The activities of the catalysts differ greatly when the catalysts support on different activated carbons. The results show that the effect of the surface physical and chemical characteristics of activated carbon on the activities of catalysts is significant. There is no direct relationship between catalyst activities, the surface area, and the total pore volume of activated carbon; but the ash content, pH value and meso-pore volume influence the activity obviously. Proper oxidation treatment of activated carbons can improve the activity. We also found that there was a strong interaction among the promoter, the support and the ruthenium. When we changed the promoter quantities, the activities of the catalysts were affected clearly.Study showed proper increase K content can improve the catalyst's low temperature activity." @default.
