摘要：
The performance of a commercial zeolite NaA pervaporation membrane supplied by Smart Chem., U.K.) was studied with respect to the dehydration of industrial mixtures of tetrahydrofurane/water (C(H2O)less than or equal to7.9 wt.%) and acetone/water (C(H2O)less than or equal to3.25 wt.%). The influence of water concentration and temperature in the range 40 degreesC - 65 degreesC on fluxes and selectivities was described. The stability, of the membrane in consecutive operation cycles is also reported.
