  • Patent number: 11896955
    Abstract: The invention discloses a method for preparing a chlorine adsorption material for use in waste incineration and application of the chlorine adsorption material. The chlorine adsorption material adsorptive for chlorine-based substances during the waste incineration is prepared by mixing raw materials which include natural iron ores and quartz stones, and modifying the iron ores and the quartz stones with CaO through an ultrasonic impregnation method. The prepared chlorine adsorption material has a large pore size, a high porosity and a stable structure, and shows higher adsorption efficiency and adsorption capacity for the chlorine-based substances during the waste incineration. The use of the low-cost natural iron ores and quartz stones can reduce the cost in processing the chlorine-based substances, make great use of resources and facilitate environment protection.

  • Patent number: 10759686
    Abstract: A method for preparing a thinning ceramic additive using a landfill leachate, comprising the following steps: filtering the landfill leachate; adding aqueous alkali and regulating pH to 7.5-9; adding a coagulant, then stirring and mixing with a blender; taking precipitates to mix with water to prepare a solution, adding a sodium hydroxide solution for alkalization, and regulating the pH to 7-8.5; adding a sulfonating agent, and reacting under an environment of 80-100° C. for 2-4 h; adding acrylic acid and N,N?-methylene bisacrylamide to the solution, then slowly adding the initiator, stirring under the condition of 80-90° C. to react for 1-3.5 h, and after the reaction is completed, drying the solution to obtain a solid matter; crushing the solid matter, and screening through a screen of 16-24 meshes; and uniformly mixing the above screened particulate matter with the montmorillonite and an additive to prepare the thinning ceramic additive.
