Preparation of Coke from Semi-coking and Non-coking Coals

• The cost of the coke will be significantly reduced by reducing the quantity of hard coking coal used in coke coke-making process
• Indian semi-coking coals can be used for coke making

• Preparation of metallurgical grade coke using semi-coking and non-coking coals
• Determination of coal blend composition for coke making.
• The coke will have a CSR of more than 60 % and a CRI of less than 25%
• Indian coking coals and semi-coking coals can be used for coke making
• Identification of active coking component in hard coking coal and soft coking coal
• Estimation of % yield of the active coking component in soft coking coal as well as hard coking coal
• Determination of blending composition of coal using non-coking coal (20% or more) to achieve quality coke for blast furnace application.

• The cost of the process of coke making will be significantly reduced by reducing the use of hard coking coal
• Yield % of active coking component in coking coal is one of the important parameters to understand the coal quality for coke making
