Activated Alumina Catalyst Support

Activated Alumina Catalyst Support is a white, spherical porous material, non-toxic, odorless, not powdering, insoluble in water and alcohol. Yuanying Activated Alumina Catalyst Support has even micro-holes, appropriate aperture size, big pore volume, high water absorption, small bulk density, good mechanical properties, good stability, suitable for catalyst support.

Alumina has been found to exist at least 8 form, they are α- Al2O3, θ-Al2O3, γ- Al2O3, δ- Al2O3, η- Al2O3, χ- Al2O3, κ- Al2O3 and ρ- Al2O3, their respective macroscopic structure properties are also different. Gamma -Al2O3 is a cubic close packed crystal, insoluble in water, but soluble in acid and alkali. Gamma -Al2O3 is a cubic close packed crystal, insoluble in water, but soluble in acid and alkali. Gamma Al2O3 carrier is weak acidic support, has a high melting point 2050 ℃, alumina gel in hydrate form can be made into the oxide with high porosity and high specific surface, it has transition phases in a wide temperature range. At higher temperature, due to dehydration and dehydroxylation, the Al2O3 surface appears coordination unsaturated oxygen (alkali center) and aluminum (acid center), with catalytic activity. Therefore, alumina can be used as support, catalyst and cocatalyst.

γ-Al2O3, was called “ activated alumina”, is a kind of porous high dispersion solid materials, because of its adjustable pore structure, large specific surface area, good adsorption performance, surface with the advantages of acidity and good thermal stability, microporous surface with requisite properties of catalytic action, therefore become the most widely used catalyst, catalyst carrier and chromatography carrier in the chemical and oil industry, and plays an important role in the oil hydrocracking, hydrogenation refining, hydrogenation reforming, dehydrogenation reaction and automobile exhaust purification process.

载体用活性氧化铝

载体用活性氧化铝为白色、球状多孔性物质、无毒、无臭、无味、不粉化、不溶于水、乙醇。远影载体用活性氧化铝微孔分布均匀,孔径大小适宜,孔容大,吸水率高,堆积密度小,机械性能好,具有良好的稳定性,适合做催化剂载体。

氧化铝已发现存在至少8种以上的形态,即α- Al2O3,θ-Al2O3,γ- Al2O3,δ- Al2O3,η- Al2O3,χ- Al2O3,κ- Al2O3和ρ- Al2O3型,其各自宏观结构性质也不尽相同。γ-Al2O3为立方紧密堆积晶体,不溶于水,但能溶于酸和碱。γ- Al2O3载体是偏弱酸性的载体,具有高的熔点2050℃,其水合物形式存在的氧化铝凝胶可制成高比表面积、高孔隙率的氧化物,在很宽的温度范围内存在过渡相。在温度较高时,Al2O3表面由于脱水和脱羟基出现了配位不饱和的氧(碱中心)和铝(酸中心),具有催化活性。因此,氧化铝可用做载体、催化剂以及助催化剂。

被称为“活性氧化铝”的γ-Al2O3是一种多孔性、高分散度的固体材料,因其具有孔结构可调、比表面积大、吸附性能好、表面拥有酸性和热稳定性好等优点,其微孔表面拥有催化作用所要求的特性,因此成为化工和石油工业中最广泛应用的催化剂或催化剂载体和色层分析载体,在石油加氢裂化、加氢精制、加氢重整、脱氢反应及汽车尾气净化等反应过程中发挥着重要作用。

由于γ-Al2O3载体的孔结构、表面酸性等性质的可调性,γ-Al2O3载体被广泛应用于催化剂载体领域。γ- Al2O3被用作载体时,除可以起到分散和稳定活性组分的作用外,还可提供酸、碱活性中心,与催化活性组分起到协同作用。催化剂的孔结构、表面性质均取决于γ-Al2O3载体,因此通过掌握γ-Al2O3载体性质的可调变规律就可制备出适合特定催化反应的高性能载体。

For air purification, the best is coconut shell.Activated Carbon apertures divide into macropore (radius 1000-1000000 A), transition hole (radius 20-1000A), micropore (radius -20A). Air purification activated carbon mainly has micropore, its apertures must be a little big than harmful gas, specific surface area and pore volume bigger is better, these are very beneficial to adsorb harmful gas.Yuanying activated carbon has big specific surface area, abundant pore structure, high mechanical strength, strong adsorption capacity, easy regeneration. It can efficaciously adsorb methanol, ammonia, radon, benzene, xylene, exhaust gas, lampblack, especially aromatic compound.Widely used for purification of carbon dioxide, hydrogen, nitrogen, chlorine hydride, ethyne, ethylene, cracking gas, inert gases, atomic equipment; As the packing of antigas mask, poison gas filter; For dropping off air pollutants and classification purification of mixed gas.空气净化活性炭外形为颗粒状或者柱状,原料一般是煤质、木质或者椰壳,其中以椰壳效果最佳。活性炭孔径分为大孔、过渡孔和微孔。大孔半径 1000-1000000 A,过渡孔半径20-1000 A,微孔半径-20A。空气净化活性炭以微孔为主,孔径必须略大于有害气体,其比表面积和微孔容积越大越好,这样非常有利于吸附有害气体。远影空气净化活性炭具有比表面积大、孔隙结构发达、吸附能力强、机械强度高、易再生等优点。能有效吸附空气中的甲醛、氨、氡、苯、香烟、油烟等有害气体及各种异味,尤其是致癌的芳香类物质。广泛应用于气体、、氮气、、、、裂化气、惰性气体等的净化;原子设施的净化;防毒面罩、滤毒器材的充填;脱降空气中污染物以及混合气体的分类提纯。

活性氧化铝脱氟剂

产品参数: 别名/化学名:Activated Alumina 分子式/结构式:Al2O3 分子量:102 密度(g/l):680 含量(%):93 产品规格:0.4-1.2, 1-3, 2-4, 3-5, 4-6, 5-7, 6-8mm Activated Alumina Defluorination AgentYuanying activated alumina defluorination agent is white spherical porous particles, uniform particle size, smooth surface, high mechanical strength, hygroscopicity strong, does not crack and inflate after absorbing water. It is non-toxic, tasteless, odorless, insoluble in water and organic solvents.Fluorine is one of the trace element necessary for animal and human. Adult normal daily intake should be 2~3 mg, too much or too little can lead to disease, so defluorination is important in drinking water. Activated alumina has good strength, good abrasion resistance, long service life, stable performance, high defluorination capacity, after defluorination the water quality accords with national health standards, so activated alumina is one of the indispensable material in water treatment.Activated alumina has amphoteric adsorption properties, by regulating the PH value of aqueous solution, anions in aqueous solution can be detached. Activated alumina defluorination equipment is similar to ion exchanger, in order to obtain high defluorination capacity, need to lower PH value, while the PH value is 5.5 activated alumina adsorption rate of fluorine is the largest. In order to meet the quality requirement and control corrosion, PH values should be slightly acidic. Activated alumina defluorination is similar to the anion exchange resin, but the selectivity for fluoride ion is larger than the anion resin. Activated alumina widely used for fluoride removal in high fluoride area, cyclic alkanes defluorination agent among alkylbenzene production.Smaller particle size can increase specific surface area, make a fully contact between activated alumina and water. For example, commonly used 1-3 mm, 0.4-1.2 mm, their specific surface area are generally more than 320 m2/g. High specific surface area means huge number of micropore, it can ensure a strong adsorption of fluoride ion in water. When raw water PH value and alkalinity is lower, defluorination capacity of activated alumina is higher, fluoride absorption of per cubic meter activated alumina is 6400 grams, fluoride absorption capacity is greater than 4.0mg/g, and the price is lower than synthetic resin. This product can also be used for dearsenification, wastewater decolorizing, deodorizing, etc.活性氧化铝脱氟剂为白色球状多孔性颗粒,粒度均匀,表面光滑,机械强度大,吸湿性强,吸水后不胀不裂保持原状,产品无毒、无味、无臭,不溶于水及有机溶剂。氟是动物与人体所必需的微量元素之一。人每天正常摄取量以2~3mg 为宜,过多或过少都会带来疾病,因此饮用水除氟显得非常重要。活性氧化铝强度好,耐磨,使用寿命长,性能稳定,除氟容量高,除氟后的水质符合国家卫生标准,是水处理不可或缺的材料之一。活性氧化铝具有两性吸附的性质,通过调节溶液的PH值,可以分离溶液中的阴离子。活性氧化铝除氟设备与离子交换器类似,为获得较高的除氟容量,需把PH值调低,PH值为5.5时活性氧化铝吸附氟速率最大。为了满足水质要求和控制腐蚀,一般来说PH值呈微酸性即可。活性氧化铝除氟类似于阴离子交换树脂,但对氟离子的选择性比阴离子树脂大。远影活性氧化铝广泛应用于高氟地区饮用水的除氟处理,烷基苯生产中循环烷烃的脱氟剂。较小的粒径可以增大比表面积,使活性氧化铝和水充分接触,例如通常使用的0.4-1.2mm、1-3mm,其比表面积一般都在320 m2/g以上。高的比表面积意味着其内部微孔数量巨大,可以保证对水中的氟离子有很强的吸附能力。当原水的PH值和碱度较低时,除氟容量较高,每立方米活性氧化铝吸氟6400克,吸氟容量大于4.0mg/g,而且其价格比合成树脂还低。本品还可用于饮用水及工业装置的除氟、脱砷、污水脱色、除臭等.

Attapulgite has stable electrochemical performance, hard to be electrolytic flocculation, high stability at high temperatures and in salt water. Widely used for desiccant, anti-blushing agent, adsorbent, catalyst support, bacteriostat support.Yuanying Attapulgite clay desiccant working temperature should be under 50℃, if temperature over 50℃, water release is bigger than water uptake. But clay desiccant is very cheap, so it becomes one of main mineral desiccant in the world.Clay Desiccant has no deformation and no fever after moisture absorption, very few water-soluble substances, no corrosion to metal.粘土干燥剂原料是凹凸棒石。凹凸棒石Attapulgite,又名坡缕石或坡缕缟石Palygorskite,矿物学分类上隶属于海泡石族,是一种层链状结构的含水富镁铝硅酸盐粘土矿物。凹凸棒石具有非常大的比表面积和一定的离子交换性,大部份的阳离子、水分子和一定大小的有机分子均可直接被吸附进孔道中;电化学性能稳定,不易被电解质所絮凝,在高温和盐水中稳定性良好。广泛用作干燥剂、防潮珠、吸附剂、催化剂载体和抗菌剂载体等。粘土干燥剂是由凹凸棒石制成。粘土干燥剂的外观形状为灰色小球,最适宜在50℃以下的环境中吸湿。当温度高于50摄氏度时,粘土的“放水”程度便大于“吸水”程度,但粘土的优势在于价格便宜。粘土干燥剂因其低廉的价格,良好的吸附效果逐渐成为国际主流的矿物干燥剂原料之一。远影采粘土干燥吸湿后不会发生变形,与水接触不发热,含有的水溶性物质很少,PH是6~8接近中性,所以不会对金属产生腐蚀。其作为吸附剂具有以下特点:1、纯天然,无毒无味,无污染,可100%自然降解;2、吸湿能力超强。同样条件下,比硅胶吸湿能力强;吸湿后不反渗,能保证干燥剂包装始终处于干燥状态;3、能选择性吸附极性分子,其吸附能力依次为水>醇>醛>酮>正烯>中性脂>芳烃>环烷烃>烷烃;4、较强脱色能力。凹土含量在75-85%,脱色力可达110-130,超过了活性白土;5、具很强灭菌、除臭、去毒、杀虫能力,可用于防护装置吸附毒气;6、由天然凹凸棒石活化、烘干而成,符合发达工业国家的“4R”和“1D”标准。粘土干燥剂广泛用于电子、电器、食品、服装、机电设备、军工、海洋运输等行业。

中空玻璃干燥剂

产品参数: 别名/化学名:insulating glass dryer 中空玻璃干燥剂,英文Insulating Glass Desiccant。在构成中空玻璃的所有原材料中,密封剂和干燥剂性能的好坏,对中空玻璃产品的使用寿命影响最大;干燥剂保证将密封在中空玻璃内部的所有水蒸气吸附干净,并吸附随着时间的推移而进入中空玻璃内部的水蒸气,保证中空玻璃的低露点寿命,它是最核心的一部分,必须具有超强的深度吸附能力、超低的氮气吸附能力、合理的酸碱性、超低的落粉度。Yuanying中空玻璃干燥剂的优点:1)超低的包装含水,能保证干燥剂具有较强的吸水性能。2)超强的深度吸附能力,能保证玻璃夹层内的水份被充分吸收,避免结露,充分保证中空玻璃的保温隔热性能。3)超低的落粉度,保证中空玻璃的美观透光性能。4)超低的氮气吸附能力,保证中空玻璃在不同的温度变化条件下,玻璃扭曲变形,导致玻璃爆裂。5)合格的堆积密度,保证干燥剂的灌装使用量控制在最经济、最合理的范围之内。6)合理的酸碱性,保证中空玻璃间隔条不易被腐蚀,出现盐析等现象。7)较高的抗压碎强度,减少因强度不够在灌装过程中破碎,形成渣、粉尘,污染玻璃。8)低静电,保证在机器填充时干燥剂吸附在管道壁上,堵塞管道。
