Patent number: 8021538Abstract: Stable catalyst carrier impregnating solutions can be prepared using a component of a Group VIB metal, e.g., molybdenum, at high concentration, a component of a Group VIII metal, e.g., nickel, at low concentration, and a phosphorous component, e.g., phosphoric acid, at low concentration, provided that the Group VIII metal is in a substantially water-insoluble form and a particular sequence of addition of the components is followed, even when a substantially water-insoluble form of the Group VIB component is used. The resulting stabilized impregnating solution can be supplemented with additional Group VIII metal in water-soluble form to achieve increased levels of such metal in the final catalyst. Furthermore, uncalcined catalyst carriers impregnated with the stable solution and subsequently shaped, dried and calcined, have unexpectedly improved performance when used in the hydroprocessing of heavy hydrocarbon feedstocks.Type: GrantFiled: April 16, 2008Date of Patent: September 20, 2011Assignee: Advanced Refining Technologies LLCInventor: Darryl P.

Patent number: 6652737Abstract: Disclosed is a method for treating naphtha. The method comprises providing naphtha feed, and the naphtha feed comprises naphthene ring-containing compounds. The naphtha feed is contacted with a ring opening catalyst containing a Group VIII metal under conditions effective to ring open the naphthene rings to form a ring opened product. The ring open product can then be contacted with a catalytic cracking catalyst under effective cracking conditions to form an olefin product. The olefin product will be particularly high in ethylene and propylene content.Type: GrantFiled: July 2, 2001Date of Patent: November 25, 2003Assignee: ExxonMobil Research and Engineering CompanyInventors: Michele S.
