To improve the supercritical fluid liquid contact, a scourer rotor was used in the extraction cell, and the column was packed with Dixon ring.
为改善气液接触,萃取器内使用了转动不锈钢箔团,精馏柱内充填了Dixon环。
A mathematic model coupled mass-transfer and reaction to match bubble column reactor with outside circulation for liquid-phase catalytic oxidation of ethylene was established. The Gear algorithm was adopted because the model was a kind of stiff ordinary differential equations.
