Extract gold using coconut shell activated carbon coconut shell activated carbon to extract gold with the appearance of black, grainy, high-quality coconut shell as raw materials is in Southeast Asia, the use of physical methods and high temperature steam activation process is refined. The product particle size uniformity, mechanical strength, high performance deodorizing charcoal adsorption ability, through post-mill and other special process, with good abrasion resistance, and high adsorption performance for modern gold mine gold mining production, the main Heap leaching is used to extract gold or CIP metallurgical industry in the separation and extraction of precious metals. Extract gold using toxic and tasteless coconut shell activated carbon coconut shell activated carbon technology parameters, with a gap developed good adsorption properties, high strength, easy regeneration, economic and durable and so on. Can also be used for drinking water, pure water, wine, beverage, industrial wastewater purification, bleaching, dechlorination, deodorant; also be used for sweetening and other refining industry. Physical characteristics: extract gold using coconut shell activated carbon micropores of activated carbon products currently on the market are different manufacturers of water purification activated carbon adsorption performance is better than existing products. Micropores by irregular regular arrangement, pore uniformity coefficient, specific surface area, iodine adsorption values ??were higher than the existing activated carbon product, per gram of activated carbon has a surface area equivalent to the 1000 m2 much . Its aperture is divided into: a large hole that r> 20knm; filter holes 150nm> r> 20knm; microporous r <150nm; ultramicropores r <50nm. Wood, coal, coconut shell activated carbon prepared by a variety of catalyst, at 179 ~ 200 ℃ formaldehyde and phosgene was converted almost completely into methylene chloride and carbon dioxide. For example, phosgene: formaldehyde molar ratio of 0.95; temperature: 179 ℃; conversion: 98.6% phosgene, formaldehyde 98.1%. If the temperature exceeds 200 ℃, phosgene and formaldehyde will generate side effects of carbon monoxide. If bone charcoal as catalyst, phosgene and methylene chloride conversion of formaldehyde generated significantly lower, about 80%, because the bone char in low carbon content, and with phosphate impurities. According to the research, the surface of activated carbon adsorption of formaldehyde to phosgene and reaction intermediates, chlorine chloroformate, then broken down into methylene chloride, and release carbon dioxide. Activated carbon can be directly placed in the room in addition to formaldehyde as for better performance of activated carbon activated carbon adsorption, 王毓丹 that only charcoal in an enclosed cabinet, drawer space, such as a smaller place, in order to fully contact with harmful gases, to strong adsorption "If the living room directly on such a large open space, the role is not large." Moreover, activated carbon adsorption can only evaporate harmful gases, and not directly to the material harmful gases sucked out. Mistakes air purifier can except formaldehyde Many people decorate the house, buy air purifiers clean air, because businesses claiming that the cleaner can effectively remove harmful gases indoor formaldehyde, benzene, and some businesses even played "formaldehyde removal rate of 99% "slogan.
