A (co)precipitation preparation process is described and also use of the composition in hydrocracking.
Claims28
An unsupported catalyst composition which comprises one or more Group VIb metals, one or more non-noble Group VIII metals, one or more zeolites, and, optionally, a refractory oxide material.
A process for the preparation of a catalyst composition, wherein one or more Group VIb metal compounds are combined with one or more non-noble Group VIII metal compounds, and with a zeolite, in the presence of a protic liquid and optionally an alkali compound, and the catalyst composition is recovered following precipitation.
A hydrocracking catalyst comprising an unsupported mixture comprising:
- a Group VIII metal selected from the group consisting of nickel, cobalt and a combination thereof;
- a Group VIB metal selected from the group consisting of molybdenum, tungsten and a combination thereof;
- and
- a zeolite selected from the group consisting of zeolite Y, ZSM-5, ZSM-12, and zeolite beta.
A method of preparing a hydrocracking catalyst, wherein said method comprises:
- combining a Group VIII metal compound, a Group VIB metal compound, and a zeolite with a liquid comprising water to form a blend;
- forming from said blend a slurry mixture comprising a precipitate comprising said Group VIII metal compound, said Group VIB metal compound, and said zeolite;
- and recovering said precipitate to provide a recovered precipitate.
