Abstract:
The pervaporation (PV) separation performance of carbon nano tube and nano silica filled polyamide membranes were compared with pure polyamide for the dehydration of ethanol. The separation of synthesized membranes was compared with each other in separation of ethanol from ethanol/water mixture via pervaporation process. Feed concentration and temperature factors effect on ethanol separation was investigated. The results demonstrated that separation factor of polyamide-carbon nano tube is approximately higher than polyamide-nano-silica. However, the permeate concentration of ethanol for polyamide-nano-silica is much better by comparison with nano tube-polyamide and pure polyamide mixed membrane membranes.
