Paraffinic jet and diesel fuels and base oils from vegetable oils via a combination of hydrotreating, paraffin disproportionation and hydroisomerization

摘要

The present invention relates to a new process which comprises the steps of hydrotreating, paraffin disproportionation and hydroisomerization to convert biological hydrocarbonaceous oxygenated oils comprising triglycerides into biologically-derived paraffinic jet/diesel fuels, solvents and base oils. A combination of conventional hydrogenation/dehydrogenation catalysts, such as Pt/Al₂O₃, and conventional olefin metathesis catalysts, such as WO₃/SiO₂, or inexpensive variations thereof, is generally employed in the paraffin disproportionation step.
