颗粒活性炭简介

 

     颗粒活性炭是一种多孔性的含炭物质,它具有高度发达的孔隙构造,其吸附作用是藉由物理性吸附力与化学性吸附力达成,其組成物质除了炭元素外,尚含有少量的氢、氮、氧及灰份,其結构则为炭形成六环物堆积而成。煤质颗粒活性炭常被应用于污水处理,空气净化等领域。

 

     煤质颗粒活性炭是世界上产量非常大的颗粒炭产品,其制造工艺分两大类:一是将原煤破碎到一定粒度后,直接炭化、活化制成颗粒状产品;另一类是将煤粉与外加粘合剂混合成型后,经炭化、活化(有时在炭化工序前后加入氧化工序)制成颗粒活性炭。成型法制造煤质颗粒炭的生产工艺又可分成两种:一种是湿法成型工艺,包括添加煤焦油作粘合剂的条柱状颗粒炭制造工艺,及添加造纸黑液或其他含可溶性纤维素的溶液做粘合剂的造球工艺;另一种是压块成型工艺(采用干粉为原料)。

 

Containing carbon granular activated carbon is a porous material, it has a highly developed pore structure, its adsorption is achieved by physical adsorption and chemical adsorption force. The material in addition to carbon element, it contains a small amount of hydrogen, nitrogen, oxygen and ash, its structure is carbon formed six ring up. Coal particle activated carbon is used in wastewater treatment, air purification and other fields.

Coal particle activated carbon is one of the world's output is very large particle charcoal products, its manufacturing process is divided into two categories: one is to break the raw coal to a certain size, carbonization and activation directly into granular products; The other is to make a particle activated carbon by mixing the coal powder with the addition of the adhesive, which is then carbonized and activated (sometimes by adding the oxidation process before and after the carbonization process). Molding in the production process to make coal particles of carbon can be divided into two kinds: one kind is wet molding process, including adding coal tar as adhesive article of columnar grain charcoal manufacturing process, and added to the papermaking black liquor or other solution containing soluble fiber adhesive pelletizing process; The other is the pressure block molding process (made of dry powder).

煤质颗粒活性炭孔径

 

       煤质颗粒活性炭采用先进工艺加工精制而成,外观为黑色颗粒,有孔隙率发达、比表面积大、吸附力强、机械强度高、易反复再生、造价低等特点,广泛用于有毒气体净化、废气处理、工业和生活用水的净化处理、溶剂回收等方面。

 

       煤质颗粒活性炭的孔隙按孔径的大小可分為三类。大孔:半径1000 - 1000000 A。过渡孔:半径20 - 1000 A。微孔:半径- 20 A。由不同原料制成的活性炭具有不同大小的孔径。由椰壳制的活性炭具有***小的孔隙半径。木质活性炭一般具有***大的孔隙半径,它们用於吸附较大的分子,並且用于液相中。在都市給水处理领域中使用的***一种类型之粒状活性炭即是用木材制成的称为木炭,煤质活性炭的孔隙大小介於两者之间。

 

Coal granule activated carbon refined from the use of advanced processing technology, the appearance of black particles, have developed porosity, large specific surface area, strong adsorption capacity, high mechanical strength, easy to repeated regeneration, low cost, widely used in toxic gas purification, waste gas treatment, industrial and domestic water purification treatment, solvent recovery, etc.

The pore size of coal particle activated carbon can be divided into three types. Large hole: radius 1000-1000000 A. Transition hole: radius 20-1000 A. Micropore: radius - 20 A. Activated charcoal made from different raw materials has different sizes. Activated charcoal made from coconut shells has the smallest pore radius. The wood activated charcoal has the largest pore radius, which is used to absorb larger molecules and is used in the liquid phase. The first type of activated charcoal used in urban water treatment is made of wood, called charcoal. The pore size of coal active carbon is somewhere in between.
