Abstract
The present invention relates to a process for dechlorinating a spent lubricating oil fraction, optionally mixed with another hydrocarbon stock. Upstream of the recycling operation in refining the spent oil, the latter is subjected to a dechlorination operation at least partially by passing it on a bed of particles (6) of a composition which neutralizes by absorption and containing, as active compound capable of fixing the chlorine, at least one metal oxide and/or at least one metal hydroxide.
