ABSTRACT:
The invention includes a process of making a lubricating oil composition including: a process for making a high VI lubricating oil composition including the steps of (1) contacting a waste plastics feed including mainly polyethylene in a pyrolysis zone at pyrolysis conditions, whereby at least a portion of the waste plastics feed is cracked, thereby forming a pyrolysis zone effluent including 1-olefins and n-paraffins; (2) passing the pyrolysis zone effluent, including a heavy fraction and a middle fraction, the pyrolysis effluent middle fraction including 1-olefins, to a separations zone; where the pyrolysis effluent heavy fraction portion is separated from the pyrolysis effluent middle fraction; (3) passing the pyrolysis effluent heavy fraction to a hydrogenation zone; and (4) passing at least a portion of the hydrogenation zone effluent to a catalytic isomerization dewaxing zone, where at least a portion of the hydrogenation zone effluent is contacted with a isomerization dewaxing catalyst at isomerization dewaxing conditions thereby forming a high VI lubricating oil composition.
