High quality activated carbon

Product Description: Brief introduction Activated carbon, also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes substituted with active. Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 3,000 m2 (32,000 sq ft), as determined by gas adsorption .An activation level sufficient for useful application may be attained solely from high surface area; however, further chemical treatment often enhances adsorption properties. Activated carbon is usually derived from charcoal and is sometimes utilized as biochar. Those derived from coal and coke are referred as activated coal and activated coke respectively. Appearance: The appearance of Activated Carbon is the black powder or lumpish solid. There have Honeycomb Activated Carbon, granular Activated Carbon and Carbon crystal. Usage: 1. Activated carbon for automobile gasoline evaporative emission control. 2. Activated carbon for industrial desulphurization(removing SO2),special for electrical generation plant. 3. Biological activated carbon. 4. Impregnated activated carbon. 5. Special activated carbon with low arsenic, for drinking water. 6. Special activated carbon with low ash and high purity for drinking water. 7. Various types of activated carbon for municipal water treatment, waste water treatment and gas purification.

semi graphitization petroleum coke for sale

Product Description: Brief Introduction: Semi-graphitized petroleum coke is made from high quality petroleum coke under a temperature of 2,500-3,500°C. As a high-purity carbon material, it has characteristics of high fixed carbon content, low sulfur, low ash, low porosity etc.It can be used as carbon raiser (Recarburizer) to produce high quality steel,cast iron and alloy.It can also be used in plastic and rubber as an additive. •Application: Semi-Graphite Petroleum Coke is widely used as Carburant in the steel-making industry and precision casting industry, reduction pregnant agent in the casting industry, reducing agent in metallurgical industry and as one kind of refractories, etc. Semi-Graphite Petroleum Coke could promote the nucleation of the graphite in liquid iron, increase the amount of spheroidal graphite, and improve the structure and the grade of grey iron. Based on the microstructure observation, the features of Semi-Graphite Petroleum Coke are as the following: First, it can greatly increase the proportion of ferrite content of the nodular cast iron without pearlite stabilizer; Second, it can increase the percentage of V and VI shaped graphite when it is used; Third, comparing with the improvement of the shape of spheroidal graphite, the great increase of spheroidal graphite amount can decrease the usage of expensive nucleating agent for later micro-adjustment and save the cost remarkably.
