Chapter 4: Secondary Processing of Plant Oils
Published:15 Nov 2011
Glycerol has an important role to play in advanced oil crop biorefineries. Initially the chapter outlines processes which could be used to purify glycerol that emerges as a by-product from biodisel production. Glycerol in a clean form is in fact a highly valuable chemical and if such purification processes could be optimised, this approach could be a lucrative add-on for many biodisel manufacturers. However in order to conduct any chemical derivitisation, this purification process is a must anyway. There is a vast range of high value chemicals which can be produced and the chapter outlines key processes and products. Interestingly the novel concept of manufacturing biodiesel without any glycerol by-product is also discussed as an ultimate green process.
