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 metallurgical applications has been evaluated, order to reduce CO2 emissions these processes. On one hand, comparative study between commercial reducers carried out. other different proportions this have added an industrial coking coal blend carbonized together semi-pilot movable wall oven, influence plastic mechanical properties produced biocoke. fulfills requirements be used reducer non-ferrous processes where no strength is required, like rotary kilns, substitution fossil reducers. Its higher heating value (>32 MJ kg−1) range or over those coals, with advantage not containing polluting elements (S, N) having less ash. addition up 0.9 wt.% almost does affect quality biocoke; but ≥2 degrades biocoke below demanded requirements. Moreover, reactivity seems independent amount added.
