利用两环境矩直接积分模型(DQMOM)对喷射器内液液平行一竞争反应体系进行了研究,结果表明:在固定引射流速的情况下,随着喷嘴速度的增加,平行-竞争反应的选择性越来越高,副反应的转化率越来越低;在固定喷嘴流速的情况下,随着引射流体速度的增加,平行-竞争反应的选择性越来越低,副反应的转化率越来越高;速度比一定时,喷嘴绝对速度值越大,副反应的转化率越低。
A parallel reaction system of liquid and liquid in the ejector was studied by using the direct ambient moment quadrature integral model (DQMOM). The results show that with the fixed ejector velocity increasing with the increase of nozzle velocity, the choice of parallel - competitive reaction The conversion rate of side reaction is getting lower and lower; with the fixed nozzle flow rate, the selectivity of parallel-competitive reaction is getting lower and lower with the increase of the velocity of the injection fluid, the conversion rate of side reaction Higher and higher; when the speed ratio is constant, the greater the absolute nozzle speed value, the lower the conversion rate of side reactions.
