Product Details

12X40 Briqutte Granule Coal Activated Carbon for Catalyst or Catalyst Carrier

 

 

Description

 

The product is a kind of briquetted activated carbon for catalyst or catalyst carrier.

 

The production processes are accomplished by using one combination of the following steps:


1.) Carbonization: Material with carbon content is pyrolyzed at temperatures in the range of 600–900 °C, in absence of oxygen (usually in inert atmosphere with gases like argon or nitrogen)


2.) Activation/ Oxidation: Raw material or carbonised material is exposed to oxidizing atmospheres (carbon monoxide, oxygen, or steam) at temperatures above 250 °C, usually in the temperature range of 600–1200 °C. The product is also designed to comply with all the applicable provision of ASTM standard for briquetted activatedcarbon.

 

Applications

 

The product is used primarily for catalyst or catalyst carrier in synthetic industry. This carbon is a coarser mesh media and is generally used in deep bed filters where pressure drop may be concerned. It functions as a dual purpose media providing both filtration and adsorption.

Advantages

 

Having high hardness, the product can reduce the generation of fines and product losses during backwashing. Complicated pores structure provides an equal blend of low and high energy, also for effective removal of abroad range of high and low molecular weight organic compounds.Wets readily and do not float, thus minimizing loss during backwash operations.Create optimal transport paths for faster adsorption.
