  • Patent number: 8637418
    Abstract: A method for treating a catalyst base that comprises a contact area of porous material. A fluid, such as a flue gas stream, can be conducted along the contact area. A catalytically relevant substance is introduced into pores of the catalyst base using a transport fluid and remains on pore wall areas after removal of the transport fluid. The introduction is carried out such that an amount of the catalytically relevant substance relative to the surface remains on the pore wall areas as a function of location within the pore and decreases within the pore after exceeding a specific pore depth. A blocking fluid can first be introduced into pore regions beyond the specific pore depth, thus blocking these regions when transport fluid containing the catalytically relevant substance is introduced.

    Abstract: The oxidative dehydrogenation of propane provides a highly selective catalyst for the oxidative dehydrogenation of propane to propylene, and a process for preparing the catalyst. The catalyst is a mixed metal oxides catalyst of the general formula MoaVbOx, where the molar ratio of molybdenum to vanadium is between 1:1 and 9:1 (a:b is between 0.5:0.5 and 0.9:0.1) and x is determined according to the oxidation state of the cations present. The catalyst is prepared by mixing the metals by sol-gel technique, heating the gel to dry the mixed oxides, further heating the dried product to induce auto-combustion, washing the product with isopropyl alcohol, and drying with a supercritical CO2 dryer. Oxidative dehydrogenation is carried out by contacting a stream of propane gas with the bulk mixed metal oxides catalyst at a temperature between 350° C. and 550° C. Propylene selectivity of 100% is reached at conversion rates between 1.9% and 4.8%.

  • Patent number: 8586500
    Abstract: 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. In the present disclosure, the metals 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 metal ions in at least one of the metal residuals, and for at least one of the metal residuals is recovered as a metal precursor feed, which can be recycled for use in the co-precipitation reaction. An effluent stream from the process to waste treatment contains less than 50 ppm metal ions.

  • Patent number: 8586786
    Abstract: A catalyst for use in the production of an unsaturated aldehyde and/or an unsaturated carboxylic acid, the catalyst comparing (or, preferably, being composed of) a mixed oxide containing molybdenum, bismuth and iron, which has improved methanical strength, is produced by a method including the steps of (1) drying an aqueous solution or an aqueous slurry containing raw materials of the catalyst and then firstly calcining a dried product in a molecular oxygen-containing gas atmosphere to obtain a calcined product; (2) heating the calcined product obtained in Step (1) in the presence of a reducing material to obtain a reduced product having a mass loss of 0.05 to 6%; and (3) secondly calcining the reduced product obtained in Step (2) in a molecular oxygen-containing gas atmosphere.

  • Patent number: 8575062
    Abstract: 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.

  • Patent number: 8575061
    Abstract: In a process for forming a bulk hydroprocessing catalyst by sulfiding a catalyst precursor made in a co-precipitation reaction, up to 60% of metal ions in at least one 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 via ion-exchange, wherein an exchange resin is provided for a portion of the metal ions in the supernatant to be exchanged and bound onto the resin. The previously resin-bound metals can be subsequently recovered, or the effluent stream for the exchange resin column can also be recovered, forming at least a metal precursor feed which can be used in the co-precipitation reaction.

  • Patent number: 8563774
    Abstract: Disclosed is a method for producing a catalyst, in which physical properties of a dried material or a calcined material in a production process of the catalyst are stable and a change in at least one of a catalyst activity and a selectivity to a target product is small and hence reproducibility of the catalyst is excellent. The present invention is a method for producing a catalyst containing molybdenum, bismuth, and iron, which contains the steps of washing a surface of at least one device equipped in an apparatus for the production of catalyst, to which a solid matter adheres, with a basic solution, and producing the catalyst with the apparatus for the production of catalyst thus washed.
