Publication number: 20120271081Abstract: The invention relates to a process for producing distillate from a charge of heteroatomic organic compounds comprising at least one heteroatom chosen from oxygen, sulfur and halogen, alone or in combination, in which the treatment of the charge comprises at least one step of conversion of the heteroatomic organic compounds into olefins performed in a first conversion zone, and, in at least a second oligomerization zone, a step of oligomerization of olefins originating at least partly from the conversion zone, in the presence of at least 0.5% by weight of oxygenated compounds, in order to produce a distillate. By virtue of the presence of oxygenated compounds during the oligomerization, this process makes it possible to improve the yield of distillate, making it possible to obtain a higher degree of oligomerization relative to the oligomerization of the same charge under the same reaction conditions.Type: ApplicationFiled: October 13, 2010Publication date: October 25, 2012Applicant: TOTAL RAFFINAGE MARKETINGInventors: Nikolai Nesterenko, Delphine Minoux, Sander Van Donk, Jean-Pierre Dath

Publication number: 20120271085Abstract: The invention relates to a method for converting a hydrocarbon feed containing C3-C10 olefins into a distillate, whereby the quantities of olefins having a chain length that is too short can be reduced in order to be exploited (typically C10 or even less) and the C10+ molecule yields can be increased, while controlling the exothermicity of the oligomerisation reactions. This effect is obtained by oligomerising the hydrocarbon feed in the presence of at least one part of the products resulting from the pre-conversion, by means of condensation, of light oxygen molecules (comprising at least one alcohol having at least two carbon atoms) which can originate from biomass.Type: ApplicationFiled: October 13, 2010Publication date: October 25, 2012Applicant: TOTAL RAFFINAGE MARKETINGInventors: Nikolai Nesterenko, Delphine Minoux, Sander Van Donk, Jean-Pierre Dath
