Georgia Institute of Technology researchers upgrading lignin bio-oil to hydrocarbons

September 24, 2020 |

In Georgia, a new low-temperature, multi-phase process for upgrading lignin bio-oil to hydrocarbons could help expand use of the lignin, which is now largely a waste product left over from the production of cellulose and bioethanol from trees and other woody plants.

Using a dual catalyst system of superacid and platinum particles, researchers at the Georgia Institute of Technology have shown they can add hydrogen and remove oxygen from lignin bio-oil, making the oil more useful as a fuel and source of chemical feedstocks. The process, based on an unusual hydrogen cycle, can be done at low temperature and ambient pressure, improving the practicality of the upgrade and reducing the energy input needed.
