Biodiesel can be processed by esterification or by biomass-to-liquid (BTL) process. Neste Oil has developed a BTL diesel component NExBTL utilizing a proprietary conversion process for vegetable oils and animal fats.
NExBTL biodiesel properties are similar to the best existing diesels such as GTL or Swedish Environmental Class 1 fuels. NExBTL is sulfur-, oxygen-, nitrogen- and aromatic free and has very high cetane number. Product meets the requirements set by EN590 and WWFC category 4 except for density.
Cold properties (cloud point) of NExBTL can be adjusted in the production from -5 … -30°C to meet the needs of various climatic conditions. Heating value is similar to the EN590 hydrocarbon fuel, storage stability is good and water solubility low. NExBTL biodiesel is compatible with the existing vehicle fleet as well as diesel fuel logistic system and is technically easy to blend in conventional diesels in all ratios.
NExBTL in diesel blends decrease both regulated and unregulated exhaust emission components. Decrease in emissions is dependent on the proportion of NExBTL. NExBTL blends do not have an impact on fuel consumption.
