Process for the hydrotreatment of a mixture of C4 to C8 hydrocarbon-based compounds, rich in olefins and monoaromatic compounds, by hydrogenation in the presence of a solid catalyst, characterized in that an ammonia precursor is introduced into the charge of hydrocarbon-based compounds and in that the catalyst comprises at least one transition metal supported on at least one refractory oxide.

Method for hydrotreatment of a mixture of hydrocarbon compounds, rich in olefins and aromatic compounds

The wax-containing hydrocarbon feedstocks are pre-treated by contacting them with a homogeneous solution containing 1-5 vol. % of an acid diluted in an alcohol/water mixture (preferably containing 60-90 vol. % alcohol). The pre-treated feedstock is then contacted, in the presence of hydrogen, with at least two catalysts in sequence and with no intermediate separation, comprising at least one hydrodewaxing catalyst and one hydrocracking catalyst, to recover high-grade middle distillates.
