Patent ID: 8088961

Claim:
A process for making a pour point depressing lubricant base oil blending component for blending with a lubricant base oil to produce a lubricant base oil blend, comprising the steps of: determining a target pour point of the lubricant base oil blend; pyrolyzing a plastics feed comprising polyethylene in a pyrolysis zone at a temperature in the range of about 450° C. to about 700° C. and a residence time in the range of about 3 minutes to about 1 hour to provide a pyrolysis effluent; isomerization dewaxing at least a portion of the pyrolysis effluent with an isomerization dewaxing catalyst in a catalytic isomerization dewaxing zone to provide an isomerization dewaxing effluent comprising a pour point depressing lubricant base oil blending component having a pour point higher than the target pour point; and recovering the pour point depressing lubricant base oil blending component boiling in the range of about 900° F. to about 1100° F. and having a pour point in the range of about −15° C. to about 0° C., wherein the pour point depressing lubricant base oil blending component is recovered to blend with the lubricant base oil to produce the lubricant base oil blend with the target pour point.
