Abstract

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/AlO, and conventional olefin metathesis catalysts, such as WO/SiO, or inexpensive variations thereof, is generally employed in the paraffin disproportionation step.
