| 摘要 |
Described is an integrated process for converting biomass pyrolysis oil into products that will be more useful for transportation fuels as well as industrial solvents. In one embodiment, a method of stabilizing the pyrolysis oil using stabilizing agents (e.g. ethanol, methanol) is disclosed. In other embodiments, a method of obtaining a vacuum heavy fraction (VHF) and vacuum light fraction (VLF) through a vacuum distillation process of stabilized pyrolysis oil is disclosed. In other embodiments, a method to extract the stabilizing agent, and industrial chemicals from the VLF through atmospheric distillation is disclosed. Also, in other embodiments the method includes recycling the extracted stabilizing agent to stabilize the pyrolysis oil. In other embodiments, the VHF can be upgraded to transportation fuel through emulsification and catalytic processes. |
