Abstract
Bio-oil produced by fast pyrolysis of biomass is a potential source of low carbon, renewable hydrocarbon fuel. However, the properties such as low heating value, incomplete volatility, acidity, instability, and incompatibility with standard fuels restrict its use. The undesirable properties of pyrolysis oil result from its chemical composition that mostly consists of different classes of oxygenated organic compounds. Current process of hydrodeoxygenation to remove oxygen involves high-temperature, high-pressure processing in the presence of hydrogen and catalyst. An alternative process of deoxygenation of bio-oil using solid-state, oxygen conductor based electrochemical cell was investigated and the process demonstrates removal of oxygen from the oxygenated organic molecule as well from steam to produce hydrogen in-situ. Thus, this new technique provides an avenue and flexibility of directly removing oxygen with electric current and can be coupled with pyrolysis system to accelerate biomass transformation to hydrocarbon within a distributed biomass upgrading system.
