摘要
本文在气升式内循环流三相反应器中系统研究了脂肪醇类、酯类及氨基酸类添加剂对传质的影响，提出了基于无因次数Ｃｒｋ２σ的判别标准以推测传质中出现的峰值。在此基础上提出了基于２ｉ＝０Ｃｉ〔ｌｎＣｒｋ２σ＋１〕ｉ的关联式对Ｋ１α数据给予了关联，对传质特性给出了较好的预测。
The effects of emtrols,esters and amino-acids on mass transfer are investrgated comprehensively in an airlift inner-loop three-phase reactor.A criterion based on dimensionless number Crk 2σ is proplsed to estimate the peak point in mass transfer. A correlation of K 1α based on 2i=0C iCrk 2σ+1] i is developed,and gives a good estimation to the character of mass transfer
