'催化剂载体/触媒,载银活性炭-----椰壳 
      
 载体椰壳活性炭采用椰壳为原料精制而成,外形为不定形颗粒,具有机械强度高,孔隙结构发达,比表面积大,吸附速度快,吸附容量高,易于再生,经久耐用等特点。 
主要用于食品、饮料、药用活性炭、酒类、空气净化活性炭和高纯饮用水的除臭、去除水中重金属、除氯及液体脱色。并可广泛用于化学工业的溶剂回收和气体分离等。使用寿命长,种类齐全,分别为黄金提炼专用活性炭、水处理活性炭、味精精制炭、石化脱硫醇专用炭、维尼纶触媒载体活性炭、乙烯脱盐水炭、香烟过滤咀炭等等,广泛应用于食品、医疗、矿山、冶金、石化、炼钢、烟草、精细化工等行业。
 
1、气相吸附中常使用颗粒活性炭,通常是让气流通过活性炭层进行吸附。根据吸附装置中活性炭层所处状态的不同,吸附层有固定层、移动层和流动层几种。但是,在电冰霜和汽车内的脱臭器之类小型吸附器中,依靠气体的对流和扩散进行吸附。除了颗粒活性炭以外,活性炭纤维和活性炭成型物也正在气相吸附中得到日益广泛的应用。 
2、仪器室、空调室、地下室及海底设施中的空气,由于外界污染或者受密闭环境中人群活动的影响,常含有体臭、吸烟臭、烹饪臭、油、有机及无机硫化物、腐蚀性成分等,造成精密仪表腐蚀或影响人体健康。可用活性炭进行净化,除去杂质成分。
3、化工厂、皮革厂、造漆厂以及使用各种有机溶剂的工程排出的气体中,含有各种有机溶剂、无机及有机硫化物、烃类、氯气、油、汞及其他对环境有害的成分,可以用活性炭进行吸附以后再排放。 原子能设施中排出的气体中,含有放射性的氪、氙、碘等物质,必须用活性炭将它们吸附干净以后再行排放。煤、重油燃烧生成的烟气中,含有二氧化硫及氮氧化物,它们是污染大气、形成酸雨的有害成分,也可以用活性炭将它们吸附除去。   
4、椰壳活性炭用于精制气体的用例还很多,例如防毒面具、香烟过滤嘴、冰箱除臭器、汽车尾气处理装置等,都是利用活性炭卓越的吸附性能,将气体中有毒成分、对人体不利的成分或有臭味的成分除去。例如,在香烟过滤嘴中加入100~120ng活性炭以后就能将烟气中对人体有害的成分除去很大一部分。

1、椰壳活性炭在运输过程中,防止与坚硬物质混状,不可踩、踏,以防炭粒破碎,影响质量。
2、储存应储存于多孔型吸附剂,所以在运输储存和使用过程中,都要绝对防止水浸,因水浸后,大量水充满活性空隙,使其失去作用。
3、椰壳活性炭防止焦油类物质在使用过程中,应禁止焦油类物质带入活性炭床,以免堵塞活性炭空隙,使其失去吸附作用。最好有除焦设备净化气体。
4、防火活性炭在储存或运输时,防止与火源直接接触,以防着火、活性炭再生时避免进氧并再生彻底,再生后必须用蒸汽冷却降至80℃以下,否则温度高,遇氧,活性炭自燃。
coconut shell activated carbon product introduction:
using coconut shell activated carbon coconut shell as raw materials refined but become, shape of amorphous particles, has high mechanical strength, pore structure developed, specific surface area, adsorption speed, adsorption capacity is high, easy to regenerate, durable, etc.
mainly used in food, beverage, pharmaceutical, alcohol, air purification, activated carbon and activated carbon of high purity water deodorization, removal of heavy metals in water, in addition to chlorine and liquid decolorization. and can be widely used in chemical industry of the solvent recovery and gas separation, etc. long service life, complete kinds, respectively for water treatment activated carbon, activated carbon for gold extraction, monosodium glutamate refining, petrochemical thiol off special carbon, vinylon catalyst carrier activated carbon, ethylene desalted water, cigarette filter tip carbon, etc., are widely used in food, medical, mining, metallurgy, petrochemical, steel, tobacco, fine chemical industry, etc.
coconut shell activated carbon usages:
1, coconut shell granular activated carbon is often used in gas adsorption, typically by getting airflow through the activated carbon adsorption layer. according to a different layer of activated carbon adsorption device, the state in which the adsorption layer has a fixed layer, and a fluidized bed several moving layer. however, in the electric frost and deodorizer like a small car within the adsorber, relying convection and diffusion of gas adsorption. in addition to granular activated carbon, activated carbon fibers and activated carbon are being molded by gas adsorption increasingly widely used.
2, equipment rooms, air-conditioning rooms, basements and subsea facilities in the air, as a result of external contamination or affected by human activity in a closed environment, and often contain odor, smoke smell, smelly cooking oil, organic and inorganic sulfur compounds, corrosive elements , resulting in precision instruments corrosion or affect human health. available activated carbon for purification, to remove impurity components.
3, chemical plants, tanneries, paint factory and various organic solvents engineering exhaust gases containing various organic solvents, inorganic and organic sulfur compounds, hydrocarbons, chlorine, oil, mercury and other harmful to the environment ingredients that can be discharged later by activated carbon adsorption. nuclear facilities discharged gas, krypton, xenon, and other substances containing radioactive iodine, and they must be treated with activated carbon to adsorb clean again after discharge. coal, heavy oil combustion flue gas, containing sulfur dioxide and nitrogen oxides, which are atmospheric pollution, acid rain harmful ingredients, they may be removed by adsorption with activated carbon.
4, coconut shell activated carbon for gas purification is also a lot of use cases, such as gas masks, cigarette filters, refrigerator deodorant, automobile exhaust treatment device, are excellent use of activated carbon adsorption properties, the gas toxic ingredients, detrimental to human components or odor components removed. for example, after adding 100 ~ 120ng activated carbon in cigarette filters, table 3-6-2, will be able to smoke harmful to remove a large part of the ingredients.

packing
for woven bag packing nut shell activated carbon products, lined with polyethylene plastic film, bag of 25 kg net each, products in storage should be placed in acool and dry place, not the product mix and poisonous, harmful, have peculiar smell.
precautions
1, coconut shell activated carbon in the process of transportation, prevent mixed with the hard material, do not step on, step, in case of charcoal grain crushing, affect the quality.
2, in the process of transportation storage and use, will absolutely prevent water immersion, due to flooding, after a lot of water is full of activity space, lose its effect.
3, in use process, should be prohibited from tar class material to the activated carbon bed, lest jam activated carbon, lose its adsorption. it is better for decoking equipment to purify the gas.
4,coconut shell activated carbon during storage or transportation, avoid direct contact with fire, in case of fire, into the oxygen and regeneration completely avoid when activated carbon regeneration, regeneration after have to use steam cooling down to under 80 ℃, otherwise the temperature is high, meet oxygen, activated carbon combustion.
