在三相非牛顿型流体体系中，对下喷式环流反应器传质特性进行了实验研究。讨论了表观气速、能量耗散速率、导流筒直径与反应器直径比、喷嘴直径、导流筒下端距反应器底部的距离、固体装填量、羧甲基纤维素钠（ＣＭＣ）溶液浓度及其流变特性对它的影响。实验结果表明，容积传质系数随表观气速和能量耗散速率的增加有所增加，在实验条件下，发现最优的导流筒直径与反应器直径比在０．４～０．４５这一范围、固体装填量大约为３％（体积百分比）、导流筒下端距反应器底部的距离为０．０８ｍ左右。同时提出了容积传质系数的经验关联式。
In the three-phase non-Newtonian fluid system, the mass transfer characteristics of the down-jet loop reactor were experimentally studied. The effects of superficial gas velocity, energy dissipation rate, ratio of diameter of the draft tube to the diameter of the reactor, diameter of the nozzle, distance between the lower end of the draft tube and the bottom of the reactor, the loading of solids, the sodium carboxymethyl cellulose (CMC) solution Concentration and its rheological properties of its impact. The experimental results show that the volumetric mass transfer coefficient increases with the increase of superficial gas velocity and energy dissipation rate. Under the experimental conditions, it is found that the optimal ratio of the diameter of the draft tube to the reactor diameter is between 0.4 and 0.45 In this range, the solids loading is about 3% by volume, and the lower end of the draft tube is about 0.08 meters from the bottom of the reactor. At the same time, the empirical correlation of volumetric mass transfer coefficient is proposed.
