3rd generation of BioDiesel

leave a comment »

NExBTL Renewable diesel is a second generation biodiesel developed by Neste Oil.

Most commonly produced biodiesel is first generation methyl esther (FAME = Fatty Acid Methyl Esther). Fossil methanol is used in the production process in addition to renewable raw material. End product is blended into diesel. Due to current fuel specifications, maximum 5 % can be blended.

Neste Oil’s NExBTL renewable diesel is second generation biodiesel. NExBTL diesel is pure hydrocarbon which by its properties and quality is similar to fossil diesel. Wider feedstock base can be utilized in the production process. Due to quality, it is possible to blend tens of percents of NExBTL into diesel. The higher the NExBTL content is, the less there are emissions. The first NExBTL production unit will be on-stream summer 2007 in Porvoo, Finland.

Neste Oil is involved in developing third generation biodiesel technology. Third generation utilizes gasification and Fischer-Trops technology. Third generation end product does not significantly differ from NExBTL. Technology enables to exploit the whole plant (biomass) and thereby widens the feedstock base. First commercial scale third generation biodiesel plants are estimated to be on-stream 2015.
