Abstract: Pervaporation is a green，highly efficient technology of membrane separation．In order to develop the ideal membrane of pervaporation，the mass transfer mechanism for pervaporation becomes a research focus．This paper reviews several models and theories of the mass transfer process for pervaporation，including conventional and modified solution-diffusion model，pore flow model，Maxwell-Stephan theory，and molecular simulation．The characteristics and applicability of the models are compared．And the application status of the models and theories are also introduced．The research progress of the models is discussed．
