Abstract
The invention concerns a catalyst comprising a support based on alumina or silica or silica-alumina, at least one element selected from group VIII and/or group VIB, and at least one catecholamine. The invention also concerns the process for the preparation of said catalyst and its use in a hydrotreatment and/or hydrocracking process.
Claims17
A catalyst comprising a support based on alumina or silica or silica-alumina, at least one element selected from group VIII and/or group VIB, and at least one catecholamine.
A process for the hydrotreatment and/or hydrocracking of a hydrocarbon cut, comprising preparing a catalyst by
- a) bringing at least one component of an element from group VIB and/or at least one component of an element from group VIII, at least one catecholamine and optionally phosphorus, into contact with a support based on alumina or silica or silica-alumina, in a manner such as to obtain a catalyst precursor,
- b) drying said catalyst precursor obtained from step a) at a temperature of less than 200° C., without subsequently calcining it and subjecting said cut to hydrotreatment and/or hydrocracking in the presence of said catalyst.
