  • Patent number: 9095809
    Abstract: Systems and methods are provided for improving separation of gas phase streams using an adsorbent, such as 8-member ring zeolite adsorbents or DDR type zeolite adsorbents. Suitable gas phase streams can include at least one hydrocarbon, such as methane or a hydrocarbon containing at least one saturated carbon-carbon bond, and at least one additional component, such as CO2 or N2. The selectivity of the adsorbent is improved by selectivating the adsorbent with one or more barrier compounds. The presence of the barrier compounds is believed to alter the relative ability of potential adsorbates to enter into and/or move within the pores of the adsorbent.

    Abstract: The present invention relates to a bifunctional catalyst for a hydrodewaxing process with improved isomerization selectivity, and to a method for manufacturing the same, and more particularly to a bifunctional catalyst and to a method for manufacturing same, which is characterized in that EU-2 zeolite with a controlled degree of phase transformation is used as a catalyst support having an acid site. The EU-2 zeolite, the degree of phase transformation of which is controlled, includes, by controlling synthesis parameters of EU-2, predetermined amounts of materials that are phase-transformed from EU-2 crystals such as cristobalite and quartz. The metal loaded bifunctional catalyst according to the present invention improves selectivity of the isomerization process, rather than a cracking reaction, during a hydroisomerization reaction of n-hexadecane. Therefore, the bifunctional catalyst can be widely used as a catalyst for a dewaxing process such as lubricant base oil and diesel oil.

  • Patent number: 8642493
    Abstract: [Task] To improve activity of a lower hydrocarbon aromatization catalyst and the catalyst stability. [Solving Means] In a method for producing a lower hydrocarbon aromatization catalyst to produce an aromatic compound by a catalytic reaction using a lower hydrocarbon as a raw material, the catalyst includes a metallosilicate on which molybdenum is supported, a silane in 0.75 weight % or more relative to the metallosilicate component is supported, and the catalyst is prepared by conducting a compressive shaping without adding an inorganic binder that binds particles of the catalyst. As a result, the lower hydrocarbon aromatization catalyst maintains a sufficient shape-retaining property even by a compressive shaping in a binderless manner. Stability of the catalyst and activity of the catalyst improve by subjecting the lower hydrocarbon aromatization catalyst to a compressive shaping in a binderless manner. Its advantageous effect is conspicuous when the amount of addition in terms of silicon oxide is 0.

    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.

In some embodiments, the transition metal is deposited in a precursor solution onto a zeolite extrudate to form an intermediate integral catalyst wherein prior to the deposition, the zeolite has been subjected to an initial ion exchange with protecting cations which exchange with the protons of the zeolite. The intermediate integral catalyst is heated to decompose the transition metal, and the catalyst is subsequently subjected to a secondary ion exchange with an ionic ammonium complex which exchanges with the protecting cations. The resulting ammonium treated catalyst is heated to a temperature sufficient to decompose the ammonium complex to form ammonia and H+ ions. The transition metal in the resulting catalyst is in the form of reduced crystallites located outside the zeolite channels.

  • Patent number: 8445134
    Abstract: An electrochemical cell for a secondary battery is provided, which includes a positive electrode having an intercalation cathode material of bentonite; a negative electrode material having an anode material containing one of magnesium and sodium; an electrolyte positioned in contact with at least one of the positive electrode and the negative electrode; wherein, when the anode material contains magnesium, the electrolyte is a solid gel polymeric electrolyte; and wherein, when the anode material is sodium, the electrolyte is a salt electrolyte, both the anode material and the electrolyte are molten at the operating temperature of the battery, and the cell further comprises a beta alumina solid electrolyte separator between the negative electrode and the electrolyte. To increase its conductivity, the bentonite material is treated, before cell assembly, with an acid and/or intercalated with an anilinium ion, which is then polymerized to form a polyaniline within the bentonite framework.

  • Publication number: 20120318713
    Abstract: Processes described include reacting a fresh or spent catalyst, or sorbent, with a solution containing an extracting agent (such as an acid or a base). Preferably, the catalyst contains both alumina and a molecular sieve (or a sorbent), and the reaction is performed under relatively mild conditions such that the majority of the base material does not dissolve into the solution. Thus, the catalyst can be re-used, and in certain instances the catalyst performance even improves, with or without re-incorporating certain of the metals back into the catalyst. Additionally, metals contained in the catalyst, such as Na, Mg, Al, P, S, Cl, K, Ca, V, Fe, Ni, Cu, Zn, Sr, Zn Sb, Ba, La, Ce, Pr, Nd, Pb, or their equivalent oxides, can be removed from the catalyst. Some of the metals that are removed are relatively valuable (such as the rare earth elements of La, Ce, Pr and Nd).

  • Patent number: 8062987
    Abstract: A zeolite catalyst that may be used in aromatic alkylation is prepared by treating a zeolite with a phosphorus compound. The phosphorus-treated zeolite is calcined and contacted with liquid water, whereby an amount of phosphorus is removed from the phosphorus-treated zeolite. The phosphorus-treated zeolite is then heated. A method of preparing an aromatic product may also be carried out by contacting the prepared zeolite catalyst with an aromatic alkylation feed of an aromatic compound and an alkylating agent under reaction conditions suitable for aromatic alkylation.
