The invention relates to a process for the treatment of heavy petroleum feedstocks in order to produce a gas oil fraction having a sulphur content of less than 50 ppm and generally 10 ppm which comprises the following stages: Advantageously, the heavy fraction is sent for catalytic cracking. Preferably, the process is carried out with makeup hydrogen introduced in stage c) and very advantageously all the makeup hydrogen for the process is introduced in stage c). The invention also relates to a plant which can be used for implementing this process.

Process for the conversion of feedstocks resulting from renewable sources for producing gas oil fuel bases with a low sulphur content and with an improved cetane number

The invention concerns a process for slurry phase hydroconversion of liquid sulphur-containing heavy hydrocarbon feeds, in the presence of hydrogen and in the presence of a solid catalyst, said catalyst being obtained from an aqueous solution formed from at least one cobalt and/or nickel salt of at least one heteropolyanion combining molybdenum and cobalt or molybdenum and nickel in its structure. The aqueous solution is introduced into a hydrocarbon oil containing asphaltenes and/or resins to form an emulsion and said emulsion is then injected upstream or directly into the slurry reactor.

A hydrotreating method (HDT) utilizes two plants working under different operating conditions with an intermediate stripping for co-treating a mixture made up of oils of vegetable or animal origin and petroleum cuts (gas oil cuts (GO) and middle distillates) in order to produce gas oil fuel bases meeting specifications. The first plant (HDT) is more particularly dedicated to the reactions concerning oils of vegetable or animal origin in comixture while pretreating the hydrocarbon feed, whereas the second plant (HDS) works under more severe conditions to obtain diesel fuel according to standards, in particular in terms of effluent sulfur content, density and cold properties.

Methods of hydrotreating a mixture made up of oils of animal or vegetable origin and of petroleum cuts with intermediate stripping

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 up of oils of vegetable or animal origin and of petroleum cuts (gas oil cuts (GO) and middle distillates) in order to produce gas oil effluents meeting specifications with an improved cetane number. The first catalyst bed is dedicated to only the deep desulfurization reactions (HDS1) of a petroleum type feed. The effluents of the first catalyst bed having an 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 is mixed with oils of vegetable or animal origin. The resultant oil-petroleum cut mixture is then subjected to a milder hydrotreatment (HDT2). The effluents obtained at the outlet of the second catalyst bed can optionally be mixed with the predominant stream from the first bed. The process economy, the tolerance to the specifications relative to oils of animal or vegetable origin and the quality of the products obtained are thus greatly improved.
