The traditional activated carbon is in powder form and granular form. With the further research, various shapes of activated carbon have appeared.

https://www.dxdcarbon.com/(1) activated carbon fiber. By Melt Spinning of Pitch, pre-oxidation at 200 ~ 400 °C and activation at 700 ~ 1100 °C, activated carbon fibers with few mesopores and few macropores can be obtained. The specific surface area of activated carbon fibers can reach 2500 m'/go (2) . It is made by thermal decomposition deposition method, thermal shrinkage method, gas activation method, covering method, etc. . The pore size distribution of carbon molecular sieve is narrow and uniform, and it has the function of Molecular Sieve and activated carbon. At present, the research and development of carbon molecular sieve products is one of the most active fields of activated carbon research. (3) microsphere carbon. By melting petroleum pitch, coal pitch and synthetic resin and dispersing them in dispersants, micro-spheres with diameters of tens to hundreds of microns can be made, and then carbonized and activated, thus obtaining high adsorption capacity and high mechanical strength, micro-carbon with a specific surface area of 4000 ~ 5o000 m'LG. Due to its superior performance and high price, the carbon is currently sold at up to US $100/kg internationally. So far, domestic has not achieved the industrial production of such products, users are basically dependent on foreign imports. (4) formed activated carbon. The powdered activated carbon is fixed on the polyurethane foam substrate with an adhesive and can be used as a gas filter.activated charcoal costwww.dxdcarbon.com

Or will be activated carbon in the mold pressed into a variety of shapes, such as round, square, activated Carbon Plate and so on. (5) honeycomb activated carbon. Can Be produced by extrusion molding, can also be processed from activated carbon fiber. (6) activated Carbon Membrane and carbon molecular sieve membrane. Membrane separation is a common chemical separation method, which can save the trouble of adsorption and desorption. Activated Carbon Membrane and carbon molecular sieve membrane can be prepared from polymer materials, and their working temperature is higher than that of polymer membranes. At present, this technology has been applied in the United States. (7) charcoal foam. The polymer is dissolved in solvent, poured into mould to cool, then separated by vacuum sublimation to form foam, then pre-oxidized carbonized to form low-density foam carbon. (8) large granular activated carbon. The activated carbon can reduce the pressure drop of the bed and expand the application field of the activated carbon. At present, activated carbon with a diameter of more than 8 mm has been developed, and its performance has reached the international advanced level.http://www.dxdcarbon.com
