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.

A process is disclosed for the removal of metals contaminants, particularly calcium, from hydrocarbonaceous feedstocks. The process comprises mixing the feedstock with an aqueous solution of a metals sequestering agent, particularly amino-carboxylic acids, their salts, or mixtures thereof, more particularly EDTA, and separating the aqueous solution containing the metals from the demetalated feedstock.
