摘要:
Methods and systems for processing a first composition of a light hydrocarbon mixture with a 100° F. vapor pressure range from 2 to 51 psia into a second composition of aromatic hydrocarbons are provided. The method comprises contacting the first composition with a reaction zone comprising three or more operating fixed bed reactors in series, each reactor containing porous solid acid catalyst, said method further comprising the step of adding a toluene feedstock to said reaction zone under conditions in which the first composition is transformed to a second composition in an amount greater and at a percentage higher in aromatics than produced via a parallel or single reactor process with the same catalyst without the toluene feedstock, and/or contacting said second composition comprising heavy aromatics with said reaction zone to further increase amount and percentage of aromatics.

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.
