Curriculum

Upgrading of bio-oil to transportation fuels

Bio-oil, produced by fast pyrolysis or liquefaction of lignocellulosic biomass, is an aqueous, highly oxofunctionalized (but nearly sulfur-free) mixture of light-to-medium hydrocarbons containing 15–30 wt% water. Although it is considered to be a promising basis for second-generation energy carriers, the corrosive nature, low vapor pressure, high viscosity, and instability of bio-oil limit its direct application. When it is directly burned in diesel engines, bio-oil has ignition difficulties owing to its low heating value, and the thermally unstable components leading to excessive coking. In principle, the production of high-grade transportation fuels from bio-oil is feasible by hydrogenation and hydrodeoxygenation (HDO). As pyrolysis oil contains high concentrations of water along with the reactive oxygen-containing compounds, it is highly beneficial to convert the aqueous mixture under mild conditions with water-tolerant catalysts. The good solubility of hydrogen in water and the phase separation between the aqueous phase and the hydrocarbons produced, are further advantages for this approach.
