Embodiment

[0017] Example: such as Figure 1 ~ Figure 3 Shown, the present invention comprises the following steps:

[0018] Step 1, pulverizing coal series kaolin;

[0019] Step 2, mixing the potassium acetate solution with a mass fraction of 30% and the pulverized kaolin at a mass ratio of 10:1, and stirring magnetically at room temperature for 3 to 4 days;

[0020] Step 3, filtering, washing and centrifuging the stirred product;

[0021] Step 4. Dry the centrifuged product in an electric blast drying oven for 24 hours;

[0022] Step 5. Put the air-dried product into a muffle furnace and raise the temperature to 800°C for 4 hours, then cool it under natural conditions. The sodium zeolite exists in the pyrolysis product. During the entire process of calcining the compound, the X-ray of the synthetic sodium zeolite Diffraction (XRD) pattern and Raman spectrum pattern such as figure 1 shown. The basic principle of the present invention is the high-temperature phase transition of kaol...

Abstract

The invention discloses a method for preparing natrolite from a coal series kaolinite intercalation composite, and belongs to the field of coal series kaolinite. The method includes the following steps that the coal series kaolinite is smashed; a potassium acetate solution with the mass fraction of 30% and the smashed coal series kaolinite are mixed by the mass ratio of 10:1 and are stirred magnetically for 3-4 days at the room temperature; the product obtained after stirring is filtered, washed and centrifugally treated; the centrifuged product is put in an electrothermal blowing dry box to be dried for 24 h; the air-dried product is put into a muffle furnace, heated to 800 DEG C, kept at the constant temperature for 4 h and then cooled on the natural condition, and natrolite exists in the pyrolysis product. The method is simple in preparing process, convenient to operate and easy to control, and natrolite is prepared through high-temperature phase change of the potassium acetate and kaolinite composite. Compared with an existing natrolite preparing process, the preparing process of the method is relatively simple, the process flow path is obviously simplified and easy to control, and the quality of generated natrolite is much higher than that generated through the existing natrolite preparing process.

Description

technical field [0001] The invention belongs to the field of coal series kaolin, in particular to a method for preparing sodium zeolite with a coal series kaolin intercalation compound. Background technique [0002] Coal-measure kaolin is widely distributed in my country, with abundant reserves, high quality, and various types of metallogenic ages and genetic types, so it has extremely high development and utilization value. The main mineral of coal-measure kaolinite is kaolinite. The crystal structure of kaolinite is a typical 1:1 type dioctahedral layered silicate structure, and its basic layered structure is composed of a layer of silicon-oxygen tetrahedron and A layer of aluminum-oxygen octahedra is connected to each other through a common oxygen to form a crystal layer unit. In the unit layer composed of silicon-oxygen tetrahedron and aluminum-oxygen octahedron, the edge of the tetrahedron is oxygen atoms, and the edge of the octahedron is hydrogen. Oxygen groups, unit...
