- W2354421898 abstract "The effect of potassium promoters on the copper aluminum borate for dehydrogenation of o-ethylaniline to indole was investigated in self-made catalytic reactor.The crystal structure,surface acidity,reduction performance and carbon deposition were measured by XRD,TPD,TPR and TG.The results showed that the addition of potassium promoters did not change the structure of the catalyst,but it could neutralize strong acid center and improve the dispersity of crystal particles on the surface of the catalyst.Moreover,it could also bring about synergy with the active ingredients,improve the reactive performance of dehydrogenation.In the condition of which WHSV was 0.1 h-1 and mole ratio of water to o-ethylaniline is 10∶1,conversion of o-ethylaniline is about 45% on the K0%-CuAB,while the conversion of o-ethylaniline increased to 60% on the K6.05%-CuAB.Meantime,it could delay the reduction of copper oxide,and slow down the speed of the catayst's deactivation: Conversion of o-ethylaniline on the K0%-CuAB dropped from 50% to 41.3%,the conversion maintained unchanged on the K6.05%-CuAB after reaction for 80 h." @default.
