Activated carbon is a very good adsorbent, which is made from charcoal, various fruit shells and high-quality coal by physical and chemical methods, through a series of processes such as crushing, sieving, catalyst activation, rinsing, drying and sieving. It has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb various substances in gas phase and liquid phase, thus achieving the purposes of decolorization, purification, disinfection and deodorization, and decontamination. The inspection standard can be based on Chinese national standard GB, or other national standards, such as American ASTM, Japanese JIS, German DIN standard, etc. Application of activated carbon: Activated carbon is widely used in all aspects of industrial and agricultural production, such as alkali-free deodorization (refined deodorized alcohol), ethylene desalted water (refined filler), catalyst carriers (palladium, platinum, rhodium, etc. ), water purification and sewage treatment in petrochemical industry; Treatment and protection of power plant water quality in power industry: chemical catalysts and carriers, gas purification, solvent recovery, oil decoloration and refining in chemical industry; Refinement and decoloration of beverages, alcohol, monosodium glutamate mother liquor and food in food industry; Gold extraction and tailings recovery in gold industry; Sewage treatment, waste gas and harmful gas treatment and gas purification in environmental protection industry; And related industries, cigarette filters, wood floors, moisture-proof, odor absorption, automobile gasoline evaporation pollution control, preparation of various impregnating solutions, etc. Activated carbon will have a good development prospect and a broad sales market in the future.
