  • Publication number: 20220293480
    Abstract: The present invention discloses a welding method of a demetallized ceramic substrate having a surface capillary microgroove structure. The demetallized ceramic substrate includes a ceramic substrate main body and surface capillary microstructures. The surface capillary microstructures are arranged on two lateral sides of the ceramic substrate main body and the surface capillary microstructures specifically are capillary microgrooves. The welding method includes the following steps: fixing a chip to an upper surface of the demetallized ceramic substrate having the surface capillary microgroove structure, fixing the ceramic substrate with the chip to a printed circuit board having a bonding pad, and placing melted solder on the bonding pad, and driving the solder to ascend to an electrode of the chip from the bonding pad in a lower layer by means of a capillary force, thereby realizing an electrical connection between the chip and the printed circuit board.

  • Patent number: 11441089
    Abstract: Distillate boiling range and/or diesel boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. This unexpected combination of properties is characteristic of crude oils that can be fractionated to form distillate/diesel boiling range compositions that can be used as fuels/fuel blending products with reduced or minimized processing. The resulting distillate boiling range fractions and/or diesel boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight and/or volume ratio, a low but substantial aromatics content, and a low sulfur content.

  • Publication number: 20220267823
    Abstract: The disclosure discloses a genetically engineered strain for producing porcine myoglobin and fermentation and purification thereof, and belongs to the technical field of genetic engineering. The disclosure realizes efficient secretion and expression of porcine myoglobin by integrating the gene of porcine myoglobin in P. pastoris. On this basis, optimization of the medium and culture conditions of recombinant P. pastoris can significantly increase the titer of porcine myoglobin, so that the titer can reach 285.42 mg/L under fermenter conditions. In addition, by creatively adding different concentrations of ammonium sulfate to fermentation broth step by step, the purity of myoglobin obtained by final concentration is up to 88.0%, and the purification rate is up to 66.1%.

  • Publication number: 20220025282
    Abstract: Methods of refining a whole crude oil stream. The methods involve first processing the crude either through a hydrotreating reactor comprising a dewaxing reactor bed or a flash evaporation separator. The treated streams are then further processed through a demetalization reactor bed, a hydroprocessing reactor bed, or both. The stream can then be still further processed via additional hydrotreating, distillation, or both.

  • Publication number: 20210363439
    Abstract: Method of refining whole crude oil or a wide cut crude oil, the methods comprising a combination of a hydrotreating reactor, a distillation tower, and an optional flash evaporation separator. The methods can also include light ends processing, fluid catalytic cracking, reforming, hydrocracking, and demetalization. In some methods a whole crude oil is first processed through a flash evaporation separator to create a wide cut crude oil and in other methods, the flash evaporation separator is not used as the whole crude oil is first treated in a hydrotreater.
