Abstract: Systems and methods are provided for co-processing of used lubricant oils with a coker feedstock in a fluidized coking process to form lubricant base stocks. The fluidized coking process can remove contaminants and/or additives from used lubricant oils with modest conversion of the lubricant boiling range portion.
