摘要：A hydrotreating method uses two catalyst beds with the introduction, on the

last catalyst bed, of oils of animal or vegetable origin for co-treating a mixture made upof oils of vegetable or animal origin and of petroleum cuts (gas oil cuts (GO) and middledistillates) in order to produce gas oil effluents meeting specifications with an improvedcetane number. The first catalyst bed is dedicated to only the deep desulfurizationreactions (HDS1) of a petroleum type feed. The effluents of the first catalyst bed havingan effluent sulfur content below or equal to 50 mg/kg are separated into two streams.The first stream, which is predominant, is sent to the gas oil pool. The second stream ismixed with oils of vegetable or animal origin. The resultant oil-petroleum cut mixture isthen subjected to a milder hydrotreatment (HDT2). The effluents obtained at the outletof the second catalyst bed can optionally be mixed with the predominant stream fromthe first bed. The process economy, the tolerance to the specifications relative to oils ofanimal or vegetable origin and the quality of the products obtained are thus greatlyimproved.
