  • Publication number: 20250256272
    Abstract: The present invention relates to a nitrogen-doped carbon-wrapped nickel catalyst for synthesis of higher alcohols by assembly of bioethanol and a preparation method therefor. The preparation method includes the following steps: S1, subjecting a soluble nickel salt and polyacrylamide to stirring with water, completely dissolving and then drying to obtain a precursor, where a molar ratio of the soluble nickel salt to polyacrylamide is 1:(0.5-8); and S2, subjecting the precursor to pyrolysis in an inert atmosphere at 300° C.-800° C. for 1-6 hours to obtain the nitrogen-doped carbon-wrapped nickel catalyst. The catalyst prepared by the method of the present invention has an active phase with high dispersity which enables synthesis of higher alcohols by efficient assembly of small molecules, and has relatively high stability which can still maintain high conversion rate and high yield for organic phase after 10 times of repeated use.

  • Publication number: 20250229261
    Abstract: The present invention discloses an embedded hydrothermal-resistant NiSn—CS nano-catalyst and a preparation method therefor and use thereof. The method includes the following steps: firstly dissolving a Ni salt, a Sn salt and chitosan to form a sol solution; and then removing a solvent from the sol solution to obtain a gel, and subjecting the gel to carbonization treatment to obtain the embedded hydrothermal-resistant NiSn—CS nano-catalyst; wherein temperature of the carbonization treatment is 400° C. to 600° C., and duration of the carbonization treatment is 1 to 4 hours. The embedded hydrothermal-resistant NiSn—CS nano-catalyst prepared by the present invention significantly improves the dispersion of NiSn catalytic active sites and the stability of the structure and activity in hydrothermal environments.

  • Patent number: 12129999
    Abstract: A fire resistant recessed luminaire constructed of an outer steel enclosure having a cylindrical shape that is open at one end and provided with a closed base at the opposite end. The open end has a shoulder extending outward from a perimeter of the outer steel enclosure. A fire insulation layer is disposed within and against the outer steel enclosure so as to conform to an inner shape of the outer steel enclosure. An inner steel enclosure is disposed within the fire insulation layer so as to force the insulation layer against the closed base and inner side wall of the outer steel enclosure. A light diffuser has a reflector trim extending outward from a second perimeter about an open end disposed in the inner steel enclosure so as to rest against a rim extending outward from an open end of the inner steel enclosure.
