Definition
USEDOILVACUUMDISTILLATIONBOTTOMS is a very complex combination of high molecular weight hydrocarbons consisting mostly of spent polymers and organometallic based additives which have been removed as a non-volatile residue from waste lubricating oils. This material consists primarily of hydrocarbons with a carbon number greater than 25, and with high carbon to hydrogen ratios. This material will contain metals such as zinc, calcium, sodium and magnesium.
