Abstract
A hydroconversion catalyst obtained by the process described, comprising a mesoporized zeolite with healed zeolitic structure, containing at least one network of micropores and at least one network of mesopores, having an atomic Si/Al ratio within the zeolite framework of greater than or equal to 2.3 and showing reduced amount of extra-framework aluminium with regard to that of a mesoporized zeolite with no healed zeolitic structure.
Claims
exact text as granted — not AI-modified1 . A hydroconversion catalyst comprising a mesoporized zeolite with healed zeolitic structure, containing at least one network of micropores and at least one network of mesopores, having an atomic Si/Al ratio within the zeolite framework of greater than or equal to 2.3 and showing reduced amount of extra-framework aluminium with regard to that of a mesoporized zeolite with no healed zeolitic structure,
wherein the hydroconversion catalyst is obtained by a process for preparing a catalyst comprising a mesoporized zeolite, including the steps of:
A) preparation of a protonic mesoporized zeolite, which contains at least one network of micropores and at least one network of mesopores, and
B) treatment in a gas or liquid phase containing ammonia or ammonium ions to obtain the catalyst.
2 . A process for the hydroconversion of a hydrocarbon feedstock, wherein said feedstock to be treated is placed in contact with a catalyst obtained by a process for preparing a catalyst comprising a mesoporized zeolite, including the steps of:
A) preparation of a protonic mesoporized zeolite, which contains at least one network of micropores and at least one network of mesopores, and
B) treatment in a gas or liquid phase containing ammonia or ammonium ions to obtain the catalyst.
3 . A process for the hydroconversion of a hydrocarbon feedstock, wherein said feedstock to be treated is placed in contact with the hydroconversion catalyst according to claim 1 .Join the waitlist — get patent alerts
