Activated Carbon

Yuanying activated carbon has big specific surface area, abundant pore structure, high mechanical strength, strong adsorption capacity, easy regeneration.

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.

The raw materials of water treatment activated carbon have coconut shells, walnut shell, apricot, peach shell, wood, coal and so on, the coconut shell activated carbon is considered the best water treatment activated carbon. Water treatment activated carbon has powder, granule and columnar, among them granule is the most widely used. The smaller granularity, the faster absorption, but head loss increases, usually in 8-30 mesh is better.

One of important application of Activated Carbon is as catalyst support and promoter, also can be directly as catalyst. As a support, mainly used to support catalyst, lets catalyst load on its surface and makes it possesses certain physical and chemical property, support itself generally does not have catalytic activity. Common supports include activated alumina, activated carbon, molecular sieve, clay, honeycomb ceramics, monox, kaolin, diatomite, etc. Usually used “active component-support name” to indicate supported catalyst composition, for example, Pd-activated carbon catalyst for hydrogenation, Pt-honeycomb ceramics catalyst for automotive exhaust purification.
