Abstract
A method of making a catalyst suitable for hydrocracking may comprise: contacting an initial catalyst with a passivation agent to form a passivated catalyst, contacting the passivated catalyst with a metal precursor to form a doped catalyst, and heating the doped catalyst to form the catalyst. The initial catalyst may comprise acid sites, wherein the passivation agent binds to a portion or all of the acid sites on the initial catalyst.
Claims20
A method of making a catalyst suitable for hydrocracking, the method comprising:
- contacting an initial catalyst with a passivation agent to form a passivated catalyst, wherein the initial catalyst comprises acid sites, and wherein the passivation agent binds to a portion or all of the acid sites on the initial catalyst;
- contacting the passivated catalyst with a metal precursor to form a doped catalyst, wherein the metal precursor comprises one or more metals, one or more metal salts, or both, the one or more metals, one or more metal salts, or combinations thereof comprising cobalt atoms, molybdenum atoms, nickel atoms, tungsten atoms, or combinations thereof;
- and
- heating the doped catalyst to form the catalyst;
- wherein the catalyst comprises:
- from 19.9 wt. % to 97.9 wt. % of a support material;
- from 2 wt. % to 80 wt. % of a zeolitic material comprising a microporous framework, wherein the microporous framework comprises zirconium oxide and titanium oxide;
- and
- from 0.1 wt. % to 40 wt. % of one or more metals, one or more metal oxides, or both, wherein the one or more metals are chosen from cobalt atoms, molybdenum atoms, nickel atoms, tungsten atoms, or combinations thereof, wherein the one or more metal oxides are chosen from cobalt oxide, molybdenum oxide, nickel oxide, tungsten oxide, or combinations thereof, and wherein the one or more metals, the one or more metal oxides, or both, are disposed on the microporous framework, the support material, or both.
