Coal based columnar/granular/pellet activated carbon for filter salt water in aquariums
Coal based columnar activated carbon introduction:
Activated carbon is used in a broad range of applications for both industrial and residential uses that include drinking water purification, ground and municipal water treatment, power plant and landfill gas emissions, and precious metal recovery. Air purification solutions include VOC removal and odor control.
coal based columnar activated carbon is made from coal through high temperature activation .It is black in appearance, non-toxic and tasteless, with large pores. It is featured by strong adsorption capacity, high wear-resistant performance etc. Activated carbon is applied to solvent recovery, catalyst carriers, gas adsorption and water purification in the field of chemicals, environmental protection, power plant, electronics, petrochemical industry, farming, medicine, marine transportation.
Coal based columar activated carbon specification:
Cylindrical/columnar activated carbon
Iodine Absorb (mg/g)
Specific Surface Area ( m2 /g)
Loading Density (g/l)
Coal based columnar activated carbon production process:
The rotary kiln is a large, slow-rotating cylindrical tube lined with fireclay bricks. Raw material is continuously fed from a hopper into the rotary kiln which steadily turns the carbonized material inside. As a blower forces air into the kiln, the charcoal reacts with hot steam causing the internal temperature to rise to 900-1100ºC .
The material is activated by hot steam as the it moves slowly downwards. The reaction between the steam and charcoal creates pores in the internal surface area, creating more adsorptive spaces. Depending on the temperature and amount of oxygen, this process takes 25-40 minutes.
The activated carbon passes through a screw conveyor with a cooling jacket, reducing the carbon to 200ºC before it reaches the discharging pipe and drops into a cooling kiln. where it is chilled to room temperature, 30-40ºC for several minutes before being fed into a sizing machine, sorted and packed into bulk bags for storage.
