Abstract
A hydroconversion catalyst for hydrodesulfurizing feedstock while preserving octane number of the feedstock includes a support having a mixture of zeolite and alumina, the zeolite having an Si/Al ratio of between about 1 and about 20, and an active phase on the support and including a first metal selected from group 6 of the periodic table of elements, a second metal selected from the group consisting of group 8, group 9 and group 10 of the period table of elements and a third element selected from group 15 of the periodic table of elements. A hydroconversion process is also disclosed.
Claims14
A process for hydroconversion of hydrocarbon feed, comprising the steps of:
- providing a hydrocarbon feed having an initial sulfur content;
- providing a hydroconversion catalyst comprising
- a support comprising a mixture of zeolite and alumina, wherein said support comprises between about 10 and about 90% wt of said zeolite and between about 90 and about 10% wt of said alumina, said zeolite is MFI zeolite having an Si/Al ratio of between about 1 and about 20;
- and
- (2) a metal active phase on said support and comprising a first metal selected from group 6 of the periodic table of elements, a second metal selected from the group consisting of group 8, group 9 and group 10 of the period table of elements, and a third element selected from group 15 of the periodic table of elements, wherein said metal active phase contains at least about 1% (wt) of said first metal, at least about 0.5% (wt) of said second metal, and at least about 0.2% (wt) of said third element;
- exposing said feed to said catalyst under hydroconversion conditions so as to provide a product having a final sulfur content less than said initial sulfur content.
