  • Publication number: 20220144874
    Abstract: The disclosure provides a method for preparing an amphiphilic lignin nanomaterial based on pulping black liquor, an amphiphilic lignin nanomaterial, and an oil sludge detergent. In the disclosure, physical treatments such as ball milling and high-pressure jet homogenization treatment are conducted on alkali lignin at the early stage to adjust the molecular weight and size of alkali lignin and thus to give alkali lignin nanoparticles with uniform particle sizes; and on this basis, a chemical treatment such as alkylation grafting modification is conducted to give amphiphilic lignin nanoparticles with both hydrophilicity and lipophilicity. Due to the nano-size effect, the amphiphilic lignin nanomaterial has a significantly-increased specific surface area (SSA) and effectively-improved surface properties, which can reduce the oil-water interfacial tension, and emulsify the crude oil and peel off the crude oil from the surface of rock particles, so as to achieve the purpose of oil-solid separation.

  • Publication number: 20210032139
    Abstract: To promote anaerobic digestion and delay calcification, one or more signal molecules are used to regulate the microenvironment of anaerobic granular sludge. In the process of anaerobic granular sludge treatment of papermaking wastewater, AHLs (N-acyl Hyperserine Lactones) are added to papermaking wastewater before the papermaking wastewater enters the anaerobic reactor. This may occur when the proportion of microorganism in anaerobic granular sludge VSS/TSS is less than 0.6. Further, the addition of the one or more signal molecules changes the community structure of the bacteria and methanogens, promoting anaerobic digestion and delay calcification. Additionally, the microenvironment of granular sludge is regulated by adding one or more micro-signal molecules to improve the number of bacteria susceptible to calcification, improve the anaerobic digestion rate of sludge that has not been calcified, and delay the calcification rate.

  • Publication number: 20200190676
    Abstract: A graphene ternary composite direct current-carrying plate includes an anode plate and a cathode plate. Placed between the anode plate and the cathode plate is a graphene composite layer. The graphene composite layer is doped with a certain proportion of graphene in the aluminum mesh frame. The plate of the invention has small thickness, low ohmic voltage drop, good porosity, and low current loss. This reduces the electrolysis power consumption, thereby significantly reducing the product cost and effectively promoting the industrial production market of the sodium chlorate electrolysis method. The plate also reduces energy consumption and is environmentally friendly.

  • Publication number: 20200194770
    Abstract: The patent provides a method for preparing titanium-based active electrodes with high stability coating layer, which belongs to the field of electrochemistry. The patent describes the active electrode is used titanium as the substrate, multi-metal oxides as the activated catalytic layer, and dense oxides as the protective layer. The multi-metal catalytic layer is formed by pyrolysis method to form the main body of titanium-based catalytic layer, and the dense oxide protective layer is combined with Sol-gel method and electrochemical deposition method to form a dense protective layer of titanium base. It can be widely used in chlor-alkali industry, paper industry, sewage treatment and other fields.
