binary catalystの例文
- However the binary catalysts system favors low residue content . it was found that the residue content were remained at a low level with ethylene glycol as the reaction media and 6 % ( by mass ) of sulfuric acid as the catalyst in the presence of phenol . the contents of lipophilic products were investigated
- It was indicated that the yield and quality of swnts were affected obviously by the catalyst involved . after a lot of contrastive experiments , we found that binary catalyst is more active than unitary catalyst on the synthesis of swnts . the content of the elements have great effects on the final product , and the best catalyst in our experiments is fe / co / mo / al2o3 with the mixture ratio of 0 . 9 / 01 / 0 . 25 / 10 ( mole ratio )
