Taxi coal”, which is known as the king of coal, enjoying the properties of low Sulfur, low phosphorus, low ash, high chemical activity, high mechanical strength, high calorific value, high conductivity, high fixed carbon content, high recovery rate of clean coal. So our carbon additive are with the characteristics of high carbon, low sulfur, with stable effect for improving the carbon content, high absorptive of carbon.
