Abstract: The invention relates to a method for producing distillates by means of oligomerization using a C2C10 hydrocarbon filler and at least one organic oxygenated compound containing at least one oxygen atom and at least two carbon atoms. By including the addition of a substantial amount of oxygenated compounds, said method enables a reduction in the amount of olefins having chain lengths that are too short to allow the use thereof (typically in C10, or even less) and an increase in the yields of molecules in C10+, with controlled exothermicity of the oligomerization reactions.

Abstract: 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.
