Publication number: 20120189681Abstract: A layered heterostructured coating has functional characteristics that enable the controlled release of volatile agents. The coating has photocatalytic properties, since it uses titanium dioxide, its derivatives or materials with similar photocatalytic properties (2), which upon solar irradiation open and/or degrade nano or microcapsules (3) and subsequently releases in a controlled form the volatile agents contained in them.Type: ApplicationFiled: December 11, 2009Publication date: July 26, 2012Inventors: Carlos José Macedo Tavares, Femando Da Silva Pina

Publication number: 20120168350Abstract: An improved process for preparing a slurry catalyst for the upgrade of heavy oil feedstock is provided. The process employs a polar aprotic solvent to mix with the inorganic metal precursor feed to form an oil-dispersible inorganic metal precursor, at a weight ratio of solvent to inorganic metal precursor of 1:1 to 10:1; the oil-dispersible inorganic metal precursor is subsequently sulfided forming the slurry catalyst. In one embodiment, the sulfiding is in-situ upon mixing the oil-dispersible inorganic metal precursor with a hydrocarbon diluent containing a heavy oil feedstock under in-situ sulfiding conditions.Type: ApplicationFiled: December 20, 2011Publication date: July 5, 2012Inventors: Oleg Mironov, Alexander E.

Publication number: 20120152805Abstract: A method to upgrade heavy oil feedstock using an ebullated bed reactor and a novel catalyst system is provided. The ebullated bed reactor system includes two different catalyst with different characteristics: an expanded catalyst zone containing particulate catalyst having a particle size of greater than 0.65 mm; and a slurry catalyst having an average particle size ranging from 1 to 300 ?m. The slurry catalyst is provided to the ebullated bed system containing the heavy oil feedstock, and entrained in the upflowing hydrocarbon liquid passing through the ebullated bed reaction zone. The slurry catalyst reduces the formation of sediment and coke precursors in the ebullating bed reactor system. The slurry catalyst is prepared from rework materials, which form a slurry catalyst in-situ upon mixing with the heavy oil feedstock.Type: ApplicationFiled: December 20, 2011Publication date: June 21, 2012Inventors: Julie Chabot, Bruce E. Reynolds, Erin Maris, Shuwu Yang

Publication number: 20120122656Abstract: In a process for forming a bulk hydroprocessing catalyst by sulfiding a catalyst precursor in a co-precipitation reaction, up to 60% of the metal precursor feeds do not react to form catalyst precursor and stay in the supernatant. In one embodiment, at least a precipitant is added to the product mixture at a molar ratio of precipitant to metal residuals in the supernatant ranging from 1.5:1 to 20:1 to precipitate at least 50 mole % of metal ions in the residuals forming additional catalyst precursor. The remaining metal residuals can be recovered via any of chemical precipitation, ion exchange, electro-coagulation, and combinations thereof to generate an effluent stream containing less than 50 mole % of at least one of the metal residuals. In one embodiment, at least one of the metal residuals is recovered and recycled for use as a metal precursor feed in the co-precipitation reaction.Type: ApplicationFiled: October 18, 2011Publication date: May 17, 2012Inventors: Alexander E. Kuperman, Theodorus Maesen, Dennis Dykstra

Publication number: 20120122654Abstract: In a process for forming a bulk hydroprocessing catalyst by sulfiding a catalyst precursor made in a co-precipitation reaction, up to 60% of the metal precursor feeds do not react to form catalyst precursor and end up in the supernatant as metal residuals. In the present disclosure, the metals can be recovered in a chemical precipitation step, wherein the supernatant is mixed with at least one of an acid, a sulfide-containing compound, a base, and combinations thereof to precipitate at least 50% of metal ions in at least one of the metal residuals, wherein the precipitation is carried out at a pre-select pH. The precipitate is isolated and recovered, yielding an effluent stream. The precipitate and/or the effluent stream can be further treated to form at least a metal precursor feed which can be used in the co-precipitation reaction. The process generates an effluent to waste treatment containing less than 50 ppm metals.Type: ApplicationFiled: October 18, 2011Publication date: May 17, 2012Inventors: Alexander E.
