The subject of the invention is a catalyst comprising a support based on alumina or silica or silica-alumina, at least one element from group VIII, at least one element from group VIB, and at least one organic compound of formula (I) in which R1 is a hydrocarbon radical comprising from 1 to 12 carbon atoms, R2 and R3 are selected from a hydrogen atom and a hydrocarbon radical comprising from 1 to12 carbon atoms, X is selected from an oxygen atom or a sulfur atom except when R2 and R3 represent a hydrogen atom X is then an oxygen atom, Y is selected from a hydrogen atom, a hydrocarbon radicalcomprising from 1 to 12 carbon atoms, or a -C(O)R4 moiety, R4 being selected from a hydrogen atom and a hydrocarbon radical comprising from 1 to 12 carbon atoms. 本发明涉及一种催化剂，其包含基于氧化铝或二氧化硅或二氧化硅-氧化铝的载体、至少一种第VIII族元素、至少一种第VIB族元素和至少一种式(I)的有机化合物：其中R1为包含1-12个碳原子的烃基基团，R2和R3选自氢原子和包含1-12个碳原子的烃基基团，除了R2和R3均表示氢原子时，X选自氧原子或硫原子，在R2和R3均表示氢原子的情况下，X是氧原子，Y选自氢原子、包含1-12个碳原子的烃基基团、或单元-C(O)R4，R4选自氢原子和包含1-12个碳原子的烃基基团。
