Gasoline from biomass via butene

A new method for gasoline production from butene (or butylene) has been developed. Cellulose and hemicellulose in wood and lignocellulsoses can be converted to butene via levulinic acid. Then, two molecules of butene can then be converted in a dimerization process to iso-octanol that is gasoline with high octane number.

There are many groups working on this topic. Recently, Audi together with Global Bioenergies have recently announced development of this method is larger scale and will start with a pilot of 100 tons/year next year. It is an interesting development and I wish them good luck with their process!

4B. Ethanol from sugarcane in Brazil: economic perspectives
5. Vegetable oil biorefineries
6. Biogas biorefineries
7. Civilisation biorefineries: Efficient utilization of urban waste based bioresources
8. Biomass-pyrolysis for hybrid biorefineries
9. Single-cell biorefinery
Part B: White Biotechnology
10. Biocatalysis
11. White biotechnology for organic acids
12. White biotechnology for amino acids
