Products Description
Coal based activated carbon pellets has a reasonable pore structure, large surface area, light weight, strong adsorption capacity, good abrasion resistance, high mechanical strength and long working time.
It is widely used for spray booth, organic solvents,volatile gas masks toxic gas purification, gas processing, industrial and domestic water purification, solvent recovery and so on.
It has the appearance of black cylindrical particles, with reasonable pore structure, good adsorption performance, high mechanical strength, easy to regenerate repeatedly and low cost.
Application:
Coal based pellet activated carbon is widely used for purification of exhaust gas, chemical raw material gas, chemical synthesis gas, gas for pharmaceutical industry, carbon dioxide gas for beverages, purification of hydrogen gas, nitrogen gas, hydrogen chloride, ethane gas, purification and separation of atomic facility exhaust, etc. There is also impregnated activated carbon, such as KOH activated carbon, NaOH activated carbon, sulfur impregnated activated carbon, desulfurization and denitrification activated carbon, acid wash activated carbon for removing special harmful gases.

Production process:
1. Crushing and screening: Crushing the raw coal to the appropriate particle size, usually requiring 80% -95% of the coal powder to pass through a 180-200 mesh sieve to ensure the uniformity of the raw material.
2. Forming and kneading: Mix coal powder with binders (such as coal tar, starch slurry, etc.) in a certain proportion, add an appropriate amount of water, heat and knead in the kneading machine, so that the binder fully infiltrates the coal powder and forms a uniform wet material.
3. Squeezing: Wet material is extruded into cylindrical carbon strips using a molding machine, and different diameter extrusion molds (such as 0.9mm, 1.5mm, 2mm, etc.) are used to control the diameter and length of the carbon strips to ensure a regular shape.
4. Drying: The extruded wet carbon strip is air dried or dried to remove moisture and achieve a suitable degree of drying, avoiding cracking or deformation caused by excessive moisture during the carbonization process.
5. Carbonization: Place the dried charcoal strips in a carbonization furnace and heat them up to 500-700 ℃ under isolated air conditions to decompose organic matter, release volatile components, and form a preliminary charcoal skeleton. During the carbonization process, it is necessary to control the heating rate and holding time to ensure uniform carbonization and avoid cracking of the carbon strips.
6. Activation: Send the carbonized material into the activation furnace, use steam as the activator, and carry out activation reaction at 800-950 ℃.
7. Screening: Screen the activated material to separate different particle sizes of columnar activated carbon, removing debris and powder.
8. Drying and packaging: Dry the processed columnar activated carbon to the appropriate moisture content, and then package it to form the finished product.
