ABSTRACT:
A used lubricant oil recycling process is disclosed in which a used lubricating oil is injected to a delayed coker downstream of the coker furnace whereby the used oil is thermally cracked into hydrocarbon fuel products which are low in metal contaminants, sulfur and nitrogen. The used lubricant can be preheated in an independent heater to avoid a quenching effect of the process stream when added in an amount greater than about 3% by volume based on the entire volume of the feed.
