The multiphase reactor have a lot of advantages such as high coefficientofmasstransfer, good performance of mixing and easy to control etc.
多相流态化反应器具有如传质系数高,混合性能好,操作简单等优点。

RESULTS: Coefficientofmasstransfer was slowly increased as the extraction temperature elevated, and was in accord with flow and in contrast with pressure.
The masstransfer equation was introduced into heat transfer model of falling film evaporation. The radial velocity, mass diffusion coefficient and variation of film thickness were taken into account.
