Deoxygenation Process of Pyrolysis Bio-oils Using Methane and Bimetallic Catalysts
An economical and feasible process uses methane to deoxygenate bio-oil precursors, overcoming the high cost of hydrogen gas in conventional upgrading methods.
Due to its instability, poor combustion performance, and low calorific value, bio-oil is generally upgraded by reducing oxygen content. Hydrodeoxygenation is one commonly used approach. Using hydrogen gas for deoxygenation is expensive given the high cost of production and transportation. A need exists for an efficient process of converting biomass to hydrocarbons using available resources.
Researchers at Purdue University developed a process that uses methane to deoxygenate guaiacol, a model compound for upgrading pyrolysis bio-oils by deoxygenation. This process is both economical and feasible, overcoming the high cost of hydrogen gas used in conventional processes.
Advantages:
-Economic/feasible process for upgrading pyrolysis bio-oils
-Overcomes the high-cost of hydrogen gas
Potential Applications:
-Hydrodeoxygenation processes
-Bio-oils
