Coal Based Activated Carbon
Coal based activated carbon originates from coal that has undergone a steam activation process. During activation, millions of pores are created on the surface of the carbon, increasing the total surface area. Coal based carbon has mainly meso-pores and macro-pores and is very popular in gas phase purification, potable water purification, wastewater purification and aquarium/pond water purification applications.

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.
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

Shanxi Xinhua Activated Carbon Co. Ltd Introduction Our company is the most advanced coal-based activated carbon manufacturing enterprise in Shanxi, the most important coal-production province in China. Presently, we own a coal dressing product line with an annual capacity of 300,000 tons. Our plant produces 10,000 tons of desulfurization and denitrification activated carbon every year. Desulfurization and denitrification activated carbon is a newly developed transformed product, which is widely used for treating various kinds of industrial off gas. With high-quality raw materials, scientific ingredients and innovated manufacturing techniques, we have made this product able to meet advanced international level. We have a briquette carbon product line with an annual capacity of 10,000 tons. briquette carbon is an upgraded product of coal crushing carbon. It has intensive mechanical strength and developed pores. With a floatage rate of almost zero, it is used for further water treatment. Based on excellent coal from Shanxi and manufacturing techniques of international level, we are capable of producing 7,000 tons of high-quality granular and powdered activated carbon. The features are as follows: developed pores, large specific area, intensive mechanical strength, low ash content, better adsorption capacity and long service life. The products can be divided into 5 series for over 100 varieties. The 5 series are gas purification, drinking water treatment, solvent recovery, catalyst support and poison gas protection. The products can be widely used in fields like environmental protection, national defense, chemical industry, pharmaceutical industry, food refinement, textile industry and energy sources, etc. We own a high-quality carbonized material product line with an annual capacity of 60,000 tons. Through technical innovation, we have been able to utilize energy sources comprehensively, thus having a steady material supply and improved benefits.
