  • Publication number: 20230129017
    Abstract: A catalyst for catalytic oxidation-deoxidation method of unsaturated hydrocarbon-containing gas has a carrier, an active component, a first co-agent component, and a second co-agent component loaded on the carrier respectively. The active component is one or more selected from the group consisting of oxides of Pt, Pd, Ru, Rh, Ag and Ir. The first co-agent component has one or more selected from the group consisting of a rare earth metal element, a group IVB metal element and a group VIII metal element; and the second co-agent component has one or more alkali metal element and alkaline earth metal element. The deoxidation method using the catalyst eliminates the need to add a reducing gas such as H2, allows hydrocarbons to react directly with oxygen to produce CO2 and H2O, achieves the goal of deoxidating a hydrocarbon-containing tail gas, and can prevent the generation of carbon deposits.

  • Patent number: 11616451
    Abstract: A pre-chargeable DCDC conversion circuit includes a high-voltage side conversion module connected to a primary winding of a main transformer T1, a low-voltage side conversion module connected to a secondary winding of the main transformer, and a controller used for controlling the high-voltage side conversion module and the low-voltage side conversion module. A pre-charging module is connected in series in a direct-current bus of the low-voltage side conversion module, and the pre-charging module is used for pre-charging a capacitor of electric equipment connected to a direct-current bus of the high-voltage side conversion module when the complete machine is powered on. The pre-charging module and a forward DCDC share most of power devices and power loops, and only a small number of devices are added, such that the volume and cost are reduced compared with an independent pre-charging branch, and the control mode is simple.

  • Patent number: 11386595
    Abstract: The present invention discloses a method for reconstructing incomplete data of X-ray absorption contrast computed tomography (CT) based on deep learning (DL). The method includes the following steps: using a filtered back projection (FBP) algorithm to obtain an initial reconstructed image; forward projecting the initial reconstructed image to obtain artifact-contaminated complete projection sequences; using a DL technique to process the artifact-contaminated projection sequences to obtain artifact-free projection sequences; using the FBP algorithm to reconstruct the artifact-free projection sequences to obtain a final reconstructed image. Compared with the traditional incomplete data reconstruction methods, the examples of the present invention feature a simpler calculation process, fewer parameters to be manually set, a faster calculation speed and higher image quality.

  • Patent number: 9469864
    Abstract: The present invention relates to methods of use of glycosyltransferases and related novel compounds. The invention exploits the reversibility of glycosyltransferases to generate new sugars, unnatural biomolecules and numerous one-pot reactions for generation of new biomolecules having varied backbones such as enediynes, vancomycins, bleomycins, anthracyclines, macrolides, pluramycins, aureolic acids, indolocarbazoles, aminglycosides, glycopeptides, polyenes, coumarins, benzoisochromanequinones, calicheamicins, erythromycin, avermectins, ivermectins, angucyclines, cardiac glycosides, steroids or flavinoids. In preferred embodiments, the invention specifically relates to biosynthesis of anticancer (the enediyne calicheamicin, CLM), anthelmintic agents (the macrolides avermectin, ivermectin and erythromycin) and antibiotic (the glycopeptide vancomycin, VCM) natural product-based drugs developed by reversible, bidirectional glycosyltransferase-catalyzed reactions.
