Ningxia Zhengyuan Activated Carbon Co.,ltd

Coal based activated carbon originates from coal that has undergone a steam activation process Coal based carbon has mainly mesopores and macropores and is very popular in gas phase purification portable water purification wastewater purification and aquariumpond water purification applications The carbonaceous product of wood Applications Gas phase purification Water purification system

Granular activated carbons are made from rigid raw materials, giving the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continous adsorption process and offer unusual economy in cases where carbon regeneration is favorable. In liquid phase applications they remove colloids and organic substances that give undesirable odors, colors and taste to the products. They are efficiently used for water dechlorination in processes which require super chlorination as well as the removal of organic substances from the water. In vapor phase application they participate in the solvent recovery, adsorption of colors, purification of carbon di-oxide and catalyst support. They are also used to reduce the COD and BOD in effluent waste water. Granular activated carbon is produced from coconut shell charcoal by the process of steam activation. The coconut shell charcoal is fed into the rotary kiln and activated by steam at high temperatures resulting in the evaporation of impurities and opening up of pores on the surface. The resultant big particles are then crushed and sieved to get the desired particle size. Our main grades of granular activated carbon are given as under. We can customize the iodine value as well as the particle size according to your requirements

Our Powder activated carbon is manufactured using pure pine wood which is an excellent base for manufacturing activated carbons with good adsorption power. The steam activated process is done by activating the charcoal in a rotary kiln by heating at high temperatures by steam. The activated carbon that comes out from the kiln is called unwashed activated carbon. These unwashed activated carbon has higher ash and iron content. This is reduced by washing the unwashed activated carbon with acid (HCl / H2SO4) and purified water. This results in reduction of ash content to as low as 1% and iron as low as 50 ppm. The gradation of different qualities of activated carbon is done on the basis of Methylene blue value and iodine value. The iodine value is a better test as the particle size of iodine molecule is small enough to penetrate the smallest of pores. We can relate the iodine value of activated carbon directly to its surface area because of the above fact.

Anthracite coal

Anthracite is the highest rank coal and is characterized buy low volatile matter (always less than 10%) and high carbon content. It has a semi- metallic luster and is capable of burning without smoke. Semi- anthracite is coal midway between low volatile bituminous coal and anthracite. (1-6 �?�?) Ash content for dry condition no more than 4 % Volatile substances no more than 3 % Moisture no more than 9.5 % Lowest heat of combustion (GCF) at least 7,200 kcal/kg Total sulfur for dry condition no more than 1 % (0.2-1 �?�?) Ash content for dry condition no more than 30 % Volatile substances no more than 6 % Moisture no more than 10 % Lowest heat of combustion at least 5,000 kcal/kg Total sulfur for dry condition no more than 1 % (6-13 �?�?) Ash content for dry condition no more than 4 % Volatile substances no more than 4 % Moisture no more than 8 % Lowest heat of combustion at least 7,200 kcal/kg Total sulfur for dry condition no more than 1 % Trivia Content no more than 18 % (13-25 �?�?)
