Impact of the Addition of Pyrolysed Forestry Waste to the Coking Process on the Resulting Green Biocoke

The suitability of the charcoal obtained from woody biomass pyrolysis in a continuous screw reactor at 573, 773, 973, 1173 K temperature profile as fuel and reducing agent in metallurgical applications has been evaluated, in order to reduce the CO<sub>2</sub> emissions in these processes...
