The classification of the types mentioned here is mainly based on the material of columnar activated carbon. At present, there are two main types of materials for the production of columnar activated carbon, namely wood and coal. wanyang granular activated carbon In this regard, we usually divide the columnar activated carbon into coal-based columnar activated carbon and wood columnar activated carbon.
Coal-based columnar activated carbon uses high-quality wood chips, coconut shell, etc. as raw materials. The columnar activated carbon made by crushing, mixing, extruding, molding, drying, carbonization and activation has lower ash content, less impurities, and CTC than traditional coal-based columnar activated carbon. Have an absolute advantage. Mainly used:
1. Gas phase adsorption;
2. Recovery of organic solvents (benzene series gas toluene, xylene, acetone recovery in the cellulose acetate industry, CS2 recovery in the production of viscose staple fiber, etc.);
3. The removal of impurities and harmful gases is still possible at the domestic level.
Ordinary 4mm activated carbon can only adsorb 60% of CTC, not more than 70%, while the 4mm wooden columnar activated carbon produced by our company has an adsorption rate of 100% for CTC, which makes up for the lack of domestic CTC adsorption rate. Certain level! Completely replace imported products.
The coal-based columnar activated carbon is made of high-quality anthracite as the raw material, refined and processed by advanced technology, and has the appearance of black cylindrical particles; it has reasonable pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, and low cost. For the purification of toxic gases, waste gas treatment, industrial and domestic water purification, solvent recovery, etc.
