(GB / T1480.4-1999), the needle charcoal to high-quality wood chips and shells as raw materials, zinc chloride, phosphoric acid as activator, by carbonation, activation and refining, finished product adsorption capacity, impurity content low.

Zinc chloride production, with a well-developed pore structure, adsorption capacity, rapid filtration and other characteristics. Mainly applicable to a variety of amino acid industry, refined sugar decolorization, monosodium glutamate industry, glucose industry, starch sugar industry, chemical additives, dye intermediates, food additives, pharmaceutical preparations and other high pigment solution bleaching, purification, deodorization, impurity.

Powdered activated carbon in the treatment of water in the sudden smell, industrial pollutants have a good application. When using powdered charcoal, the adsorption test must be carried out according to the type and concentration of contaminants to be removed to determine the type of activated carbon and the amount of charcoal required. Before adding the powder of carbon, should pay attention to the first carbon powder made of carbon slurry evenly into the water, the longer the contact time, in addition to the better pollution effect. The use of powder charcoal should also pay attention to the following safety issues; when the dust concentration reaches a certain percentage when the case of fire is easy to occur, so the operation prohibits smoking, sparks and open flames; should avoid mixing with the oxidant; , Should pay attention to the use of dust pollution, the operator must be equipped with dust masks, to avoid inhalation in the lungs.

Production of charcoal charcoal, impurities, high purity, fast filtration, with excellent decolorization, purification, purification and other properties, mainly for a variety of injection of decolorization, refining and removal of "heat." Vitamin C and other raw materials can also be used decolorization, decolorization strong, fast filtration, for medicine, pesticides, Chinese and Western medicine decolorization, refining. And has absorbed intestinal bacteria, detoxification effect.

Adsorption, liquid phase adsorption and gas phase adsorption are two kinds. The adsorption capacity of liquid phase is often evaluated by adsorption isotherm, and the adsorption capacity of gas phase is evaluated by solvent vapor adsorption.

The adsorption isotherm shows the relationship between pressure or concentration and the adsorption amount of adsorption material under certain temperature adsorption system, that is when the temperature unchanged, measurable adsorption balance and partial pressure or concentration changes of the relationship between. With the remaining concentration as the cross axis, the adsorption curve of activated carbon with single mass can be used as the vertical axis, and the relation curve can be drawn.

When the partial pressure or concentration unchanged, measurable adsorption balance relationship between temperature and the relationship curve is drawn, namely adsorption isobar. The adsorption isotherm is the most important and common because of the adsorption of a small amount of components in an industrial facility, usually in an isothermal state.

Solvent vapor adsorption amount of said gas adsorption properties, determination of carbon tetrachloride adsorption by activated carbon particles as an example, under the specified test conditions, the provisions of the carbon layer height, flow rate, temperature, adsorption ratio determination of pipe cross-sectional area, carbon tetrachloride vapor concentration under the condition of continuously through the vapor containing a certain carbon tetrachloride the concentration of mixed air flow when activated carbon adsorption reached saturation, carbon tetrachloride adsorption activated carbon samples by the quality and quality of the sample as a percentage of carbon tetrachloride adsorption rate.

The adsorption capacity of activated carbon, it is best to use the actual activated carbon, the conditions of operation, the specific treatment of the evaluation test.
