Panda Coke Nuts Ltd

Metallurgical coke is an important raw material for pig iron production in the blast furnace. During this process the coke undergoes severe mechanical, thermal and chemical stresses. One of these is the CO2-gasification which may lead to a decisive mechanical weakening of the lump coke by increased carbon burn-off. The CO2-reactivity is influenced by different parameters as e.g. temperature, gas composition and catalytic effects.

But merely thermal treatment of the coke at temperatures above ***0 °C may result in partly decisive changes in CO*-reactivity at a standardized temperature of ***0 °C. Five metallurgical cokes produced either from different coal types or from coals of substantially different origin have been heat-treated up to ***0 °C, and the subsequent reactivity has been determined according to the NSC test procedure.
