  • Patent number: 10329181
    Abstract: A method for appropriately controlling an aeration volume for activated sludge on which aeration treatment is conducted while DO of an activated sludge mixed liquor in an aeration tank is being adjusted to substantially 0 mg/l (ultralow DO treatment). The method includes the following steps. An aeration volume correlation (G=F(Gr)) between an aeration tank and a measuring device is acquired in advance. A sample of activated sludge mixed liquor taken during ultralow DO treatment operation is temporarily intensely aerated in the measuring device and then aeration is stopped. Based on temporal changes in the measuring device DO value, an oxygen consumption rate Rr and an equilibrium DO value C1 are calculated. An appropriate aeration volume G2* of the testing device is acquired by using an Ea?G relationship formula and the like obtained in advance. An appropriate aeration volume Gr2* of the aeration tank is obtained by using the relationship G=F(Gr).

  • Patent number: 10329194
    Abstract: Highly mineralized natural materials often boast unusual combinations of stiffness, strength and toughness currently unmatched by today's engineering materials. Beneficially, according to the embodiments of the invention, these unusual combinations can be introduced into ceramics, glasses, and crystal materials, for example by the introduction of patterns of weaker interfaces with simple or intricate architectures, which channel propagating cracks into toughening configurations. Further, such deliberately-introduced weaker interfaces, such as exploiting three-dimensional arrays of laser-generated microcracks, can deflect and guide larger incoming cracks. Addition of interlocking interfaces and flexible materials provide further energy dissipation and toughening mechanism, by channeling cracks into interlocking configurations and ligament-like pullout mechanisms. Such biomimetic materials, based on carefully architectured interfaces, provide a new pathway to toughening hard and brittle materials.

The catalyst includes as components (1) chromium oxide and zinc oxide mixed metal oxides, and (2) a SAPO-34 molecular sieve. The resulting product of the reaction is relatively high in the target lower olefins and relatively low in less desirable products, including C2 and C3 paraffins, C4+ hydrocarbons, oxygenates, and methane, thereby reducing or eliminating the need for certain previously common and costly separations. The bifunctional catalyst as used in the inventive process also offers improvements in catalyst life in comparison with some methanol-to-olefins catalysts. The process may be carried out as a single unit operation.

  • Patent number: 10329211
    Abstract: Methods for the oligomerization of ethylene, and more specifically, methods for the preparation of mainly ethylene oligomers of C10 or higher are described. A method can include performing a first oligomerization of an ethylene gas using a Ni-containing mesoporous catalyst, followed by a second oligomerization using an ion exchange resin, etc. to produce ethylene oligomers of C10 or higher. The method for the preparation of ethylene oligomers can produce C8-16 ethylene oligomers in high yield without inducing deactivation of the catalyst, compared to the conventional technology of ethylene oligomerization by a one-step process.

  • Patent number: 10329216
    Abstract: The invention relates to a new catalytic composition for the alkylation of aromatic compounds with alcohols, or mixtures of alcohols and corresponding olefins, wherein said composition comprises a zeolite of the MTW type and is characterized in that it contains one or more alkaline metals in a total quantity which is less than or equal to 0.02% by weight. The use of said catalyst in the alkylation of aromatic compounds with alcohols, in particular benzene with isopropanol or ethanol, allows the formation, as by-product, of the aldehyde or ketone corresponding to the alcohol used, to be minimized: the formation of reaction by-products of said aldehydes or ketones having a boiling point very close to that of polyalkylation products, is therefore significantly reduced. This provides a considerable advantage in the subsequent transalkylation step for the recovery of said polyalkylates by transformation into the corresponding monoalkylates.
