Comparison Between The Performance Of Polymeric Membranes Based On PPEES And PES For Purification Of Biodiesel Production From Waste Cooking Oils

In the current research, purification of produced biodiesel was carried out using Polymeric membranes based on poly ether sulfone and poly phenylene ether ether sulfone. The effect of polymer type used in the body of polymeric membranes on separation characteristic of membraneswas studied. The biodiesel was produced from waste cooking oils by trans-esterification method. Three Polymeric membranes containing 16 %wt poly ether sulfone and 13, 14 %wt poly phenylene ether ether sulfone were prepared by casting technique and phase inversion method. The results of the biodiesel purifying test, including flux through the membrane, separation efficiency and SEM images revealed The prepared Polymeric membrane containing 13 %wt poly phenylene ether ether sulfone showed more suitable performance compared to other Polymericmembranes
