分子筛

Molecular sieves

分子筛

Molecular sieves are materials that contain fine and single tiny pores that can be used to adsorb gases or liquids. Small enough molecules can be adsorbed through the pores, and larger molecules can not. Unlike an ordinary sieve, it is operated at the molecular level. For example, a molecule that is small enough to pass through but larger than it does not work. Therefore, molecular sieves are commonly used as desiccants. A molecular sieve can absorb up to 22% of its own weight of water. Usually molecular sieves consist of aluminosilicate minerals, as well as synthetic mixtures or compounds. These compounds have an open structure that allows small molecules to diffuse, such as clay, porous glass, microporous charcoal, activated carbon and the like. Molecular sieves are often used in the oil industry, especially for the purification of gases. For example, silica gel can be used to adsorb the mercury in natural gas to corrosion of aluminum pipes and other liquefaction equipment. The regeneration method of molecular sieves involves changing the pressure in an oxygen concentrator and, when used for ethanol dehydration, can also be heated and cleaned with carrier gas. ... 分子筛是一种包含有精确和单一的微小孔洞的材料,可用于吸附气体或液体。 足够小的分子可以通过孔道被吸附,而更大的分子则不能。与一个普通筛子不同的是它在分子水平上进行操作。例如,一个水分子小到可以通过但比它大一点的分子就不行。因此,分子筛常用用来作干燥剂。一个分子筛能吸附高达其自身重量22%的水分。 通常分子筛由铝矽酸盐矿组成,也有合成的混合物或化合物。这些化合物具有开放结构使得小分子能够扩散,如:粘土,多孔玻璃,微孔木炭,活性炭等。 分子筛常被应用到石油工业,特别是用来纯化气体。例如可用硅胶吸附天然气中的汞对铝制管道和其他液化设备的腐蚀。 分子筛的再生方法包括在氧气浓缩器中变换压力,当用于乙醇脱水时也可用载气加热和清洗。...

Definition of 分子筛 in the Chinese dictionary

Molecular sieve with strong adsorbing material (such as aluminosilicate) molded objects. With many pore size uniform pores, can selectively adsorb some less than the size of the molecule. For liquid and gas drying, separation, purification. 分子筛 用吸附性很强的物质(如硅铝酸盐)塑成的物体。具有许多孔径大小均一的微孔,能有选择的吸附某种小于孔径的分子。用于液体和气体的干燥、分离、净化。
