Abstract
A catalytic hydrocracking process for use in refining various petroleum based feedstocks to lighter hydrocarbons. The hydrocracking process for treatment of petroleum fractions utilizes a catalyst comprising (a) a layered metal oxide of the titanometallate type intercalated with an interspathic polymeric chalcogenide, e.g., polymeric silica, (b) a transition hydrogenation metal selected from Group IVA, VIA, and VIIIA of the Periodic Table such as platinum and the like, and optionally, (c) a conventional cracking component, e.g., a large pore crystalline silicate component.
Claims34
A process for hydrocracking a petroleum fraction to lighter hydrocarbons comprising providing a feedstock containing a relatively heavy petroleum fraction and contacting said feedstock with a catalyst in the presence of hydrogen under hydrocracking conditions including an elevated temperature, the catalyst composition including titanometallate layered metal oxide material comprising a layered metal oxide and pillars of a chalcogenide of at least one element selected from Groups IB, IIB, IIIA, IIIB, IVB, VA, VB, VIA, VIIA and VIIIA of the Periodic Table of the Elements separating the layers of the metal oxide, wherein each layer of the metal oxide has the general formula
- [M.sub.x [ ].sub.y.sup.z 2-(x+y).sup.O.sub.4 ].sup.q-
- wherein M is at least one metal of valance n wherein n is an integer between 0 and 7, [ ] represents a vacancy site, Z is a tetravalent titanium metal, and wherein
- q=4y-x(n--4)
- O<x+y<2
- and (b) at least one hydrogenating metal selected from Groups IVA, VIA and VIIIA.
