A comprehensive review on degummed biodiesel

Biodiesel is derived from renewable sources like vegetable oils, animal fats and recycled cooking oil. During biodiesel synthesis, gums in the feed oil inhibit the transesterification reaction rate and increase the processing cost. Gums can be removed from feed oil by a degumming process. The present review aimed to compile current, comprehensive information of degummed biodiesel production from different vegetable oils with diverse degumming techniques and also describe its fuel related properties, chemical composition and significant by-products. It is clear from this review that biodiesel manufactured from degummed feedstocks can be a promising alternative fuel for the diesel engine and could be a major step towards the creation of an environmentally friendly transportation fuel that is relatively clean on combustion. This paper is highly encourage to degumming of feed oil prior to transesterification process.
