Coal activated carbon
has developed pore structure, good chemical stability and mechanical strength. It is a good broad-spectrum carbon adsorption material.
According to different outward appearance, the coal activated carbon can be mainly divided into coal particles and coal powder activated carbon, activated carbon has been divided into coal granule activated carbon molding (including cylindrical carbon, briquetting (or tablet carbon) and spherical carbon] and crushing the raw coal activated carbon two kinds big.
Depending on the use, it can be divided into two types: purifying water, purifying air, decolorizing, recovering solvent, and using the use of needle, protection and other kinds of activated carbon.
Because of its acid and alkali resistant, heat resistant, after and granular activated carbon adsorption saturation, easily recycled, therefore, activated carbon is necessary in modern industrial production and environmental protection of carbonaceous adsorption material.
Compared with wood and fruit shell activated carbon, coal activated carbon
with raw material sources, low cost, easy regeneration, wear resistance, low fluid resistance, etc, are widely used dry water treatment, solvent recovery, saccharin, MSG, pharmaceutical, oil and other petroleum purification, gas separation and gas purification and other fields.
In addition, some specially processed and specially processed coal activated carbon
can also be used as efficient desulfurizer, catalyst and catalyst carrier.
Table 8-1 lists the main applications and applications of coal activated carbon.
No matter in which application field and application of coal activated carbon is the main basis of using the physical and chemical properties and adsorption characteristic, make all kinds of useful or useless component in the gas phase, liquid phase medium concentration, recovery and refining and purification
