Membranes processes for the production and refining of biodiesel are being increasingly reported. Membrane technology … has attracted the interest of researchers for its ability to provide high purity and quality biodiesel fuel besides its … remarkable biodiesel yields. Membranes have numerous numbers of useful properties such as resistance to mechanical, chemical and …

Biodiesel is an environmental-friendly fuel that can replace petroleum diesel. However, after transesterification … reaction of vegetable oils, the obtained crude biodiesel must be purified. The commonly applied purification step is water … international legislation for biodiesel quality. Both processes (water washing and membrane separation) were able to reduce the …
