Abstract (en)
[origin: FR2752174A1] The invention concerns a method for treating a supported catalyst having a sulphurous compound active base and contaminated by a mercury compound. This method consists in heating the contaminated catalyst at a temperature between 300 and 1000 DEG C in an inert atmosphere. As a result of this treatment, the catalyst has the same characteristics as it had before being contaminated by mercury.
