Abstract (en)

[origin: FR2875809A1] Hydrodesulfuration of a hydrocarbon cut(HC) containing at least 5% of olefins in wich the cut is mixed with a hydrogen supply(HYD) and recycled hydrogen(REC) at the inlet to the reactor.The reactor contains a desulfuration catalyst in conditions enabling transformation of sulfur compounds to hydrogen sulfide ; a purification process may be effected on the HYD/REC supply so that the overall charge comprises no more than 50 vppm of carbon monoxide and at least 120 vppm of carbon monoxide + 1/2 carbon dioxide.
