Artificial Graphite Type: Activated Carbon
Active Carbon Material: Coconut Shell
Acid washed coconut shell active carbon for water treatment and water purificationCoconut shell activated carbon is strictly selected from Southeast Asian high-quality coconut shell as raw material, refined by carbonization, activation and other series of production processes. Its appearance is black granular, non-toxic and tasteless, with developed pore structure, huge specific surface area and unique adsorption. Suitable for drinking water, purified water, industrial water and wastewater treatment, air purification, gold extraction, fish farming, etc.Type Spec.Iodine numberMg/gApparent densityG/LAsh%Moisture%Hardness%DQE1≥1300420-4604-64-5≥92DQE2≥1200450-4805-84-6≥92DQE3≥1100500-5505-84-6≥92DQE4≥1050500-5505-104-6≥94DQE5≥950550-6505-104-6≥94DQE6≥850550-6505-104-6≥94Usual particle size Mesh:8-30,8-16,12-24,16-30,6-12,6-180-1mm,1-2mm,2-4mm,3-6mm(particle size can be provided according to customer's special demands) 1.The quality of activated carbon depends on the quality of the raw materials. There are two main sources of coconut shell activated carbon in the market, one is Hainan coconut shells and the other is Indonesian coconut shells. The shells of Hainan coconuts are thin and not very dense, while the shells of Indonesian coconuts are thick and dense, so the quality of activated carbon processed from Indonesian coconut shells is better in comparison2.The selected coconut shells are put into the carbonization equipment, and after burning at high temperature to a certain extent, the kiln is closed to allow air to enter, and then the residual heat continues to heat and dry distillation to make the water and wood binder in the coconut shells to be stirred out, that is, to form coconut shell charcoal.3.The carbonized coconut shell charcoal is put into the activation furnace, so that water vapour, flue gas (the main component is CO2) and other oxygen-containing gases are used as activators to activate the charcoal at high temperature in contact with the redox reaction. The main operating conditions of the activation process include the activation temperature, the activation time, the flow and temperature of the activator, the charging rate and the oxygen content in the activation furnace.4.Activated coconut shell charcoal becomes coconut shell activated carbon at this time, then it can be sieved according to the customer's particle size requirements, commonly used coconut shell activated carbon particle size of 6-12 mesh, 8-16 mesh, 10-24 mesh, 20-40 mesh, 30-60 etc.Removal of organic species from industrial effluents.Removal of organic contaminants (and chloride from portable water).Recovery of precious metals like Gold.Removal of contaminants in gas, gas masks.Medicinal - removal of certain species in human digestive system.As a carrier for impregnates.The application in which the various activated carbon types are used is based on their key characteristics: .Coconut shell based: adsorption of smaller molecules from gas and liquids. In gas masks, solvent recovery, in cigarettes and for gold recovery.Wood based; adsorption of large usually coloured organics from industrial streams.Coal based: adsorption of a range of organic molecules that range in size. Most commonly used in portable water treatment and waste water treatment.In the gold recovery industry, activated carbon from a number of precursors has been used. Due to the nature of the in-pulp process, the following characteristics are important:1.High affinity towards gold - kinetic activity and equilibrium loading2.Hard, resistant to abrasion3.Density, suited to mixing in pulp4.Source material supply not limiting1.DensityThe density of wet carbon is in the region of 1.3 to 1.5 t/m³ , thus the density of the pulp must be similar in order to suspend and distribute the carbon evenly. If the pulp density is too low, then the carbon will sink to the bottom of the contactor, if the pulp density of the pulp is too high, the carbon will float. In both cases insufficient mixing will occur, resulting in a lower gold recovery.Activated carbon has a bulk density of 0.500 g/ml and a pore volume of 0.8 ml/g. If the pore volume is filled with water having a density of 1 g/ml and add the two values, the density of wet carbon is typically 1.3 g/ml.2.PARTICLE SIZE OF ACTIVATED CARBON The size ranges of activated carbon for gold recovery commonly used are:8/16 # ASTM (1.18 mm to 2.36 mm).6/16 # ASTM (1.18 mm to 3.35 mm).6/12 # ASTM (1.70 mm to 3.35 mm).
