  • Patent number: 12421466
    Abstract: A method for conversion of food waste to biofuel can include a first fermentation in which food waste is converted C2-C4 short-chain carboxylic acids, and a second fermentation in which the C2-C4 short-chain carboxylic acid are elongated into C5-C8 medium-chain carboxylic acids. Medium-chain carboxylic acids can undergo hydrogenation-dehydration of the medium-chain carboxylic acids into C5-C8 linear olefins. The C5-C8 linear olefins are then oligomerized to a C10-C25 mixture comprising olefins, paraffin, cycloparaffins, and aromatics through dimerization; and saturated to C10-C25 mixture by hydrogenation to produce the biofuel.

  • Patent number: 12270009
    Abstract: A process for converting plastic feedstock into a lubricant on an industrial scale can include a reactor having a filter integrated therein to allow for separation and recovery of catalyst so it can be washed and reused in subsequent conversion processes. Such recycling of the catalyst can allow for an industrial scale conversion process.

  • Publication number: 20240018222
    Abstract: A monoclonal antibody inhibiting an SMIM15 and application thereof; the antibody is secreted by a hybridoma cell strain 1M5. A preparation method includes: preparing mouse immunogen and an antigen for detection; preparing the hybridoma cell strain 1M5 against an SMIM15; screening an SMIM15 positive monoclonal antibody: identifying a subtype of the monoclonal antibody; detecting specificity of the SMIM15 positive monoclonal antibody; producing and purifying the monoclonal antibody in a BALB/c mouse; detecting purity of the antibody by SDS-PAGE; and performing function identification and application on the SMIM15 monoclonal antibody with WB, IHC and ELISA. According to the present application, the antibody secreted by the hybridoma cell strain 1M5 is an immunoglobulin, which is non-toxic, and can be used for Western blot and immunohistochemistry and used as an active ingredient to be made into a reagent or drug for diagnosis and treatment of SMIM15-related diseases.
