Abstract
The invention concerns a catalyst for hydrorefining and hydroconverting hydrocarbon feeds, comprising a mixed sulphide comprising at least two elements selected from elements with an atomic number selected from the group formed by the following numbers: 3, 11, 12, 19 to 33, 37, to 51, 55 to 83, 87 to 103, characterized in that the mixed sulphide results from a combination of at least one element the sulphide of which has a bond energy between the metal and sulphur of less than 50.+-.3 kcal/mol (209.+-.12 kJ/mol) and at least one element the sulphide of which has a bond energy between the metal and sulphur of more than 50.+-.3 kcal/mol (209.+-.12 kJ/mol), the mixed sulphide thus having a mean bond energy between the metal and sulphur which is in the range 30 to 70 kcal/mol (125 to 293 kJ/mol).
