Abstract: Spheroidal catalyst support, supported catalyst, and method of preparing and using the catalyst for hydrodemetallation of metal-containing heavy oil feedstocks are disclosed. The catalyst supports comprise titania alumina having 5 wt % or less titania and have greater than 30% percent of their pore volume in pores having a diameter of between 200 and 500 Å. Catalysts prepared from the supports contain Group 6, 9 and 10 metals or metal compounds supported on the titania alumina supports. Catalysts in accordance with the invention exhibit improved catalytic activity and stability to remove metals from heavy feedstocks during a hydrotreating process. The catalysts also provide increased sulfur and MCR conversion during a hydrotreating process.

Abstract: Disclosed is a method of synthesizing nano-sized tungsten-silica core-shell particles by a silica-based sol-gel process. According to the method, tungsten-silica nanoparticles are very easy to synthesize by a simple process at ambient pressure and temperature. In addition, tungsten oxide-silica (WOx@SiO2) nanoparticles including tungsten in a stable oxidation state can be synthesized. In the tungsten oxide-silica nanoparticles, the size of the tungsten protected with the silica shell can be maintained in the nanometer range without further processing. Also disclosed is a method of synthesizing nano-sized tungsten oxide (WOx) and tungsten carbide (WC) particles by further processing of the tungsten-silica core-shell particles.
