| Popis: | The partial substitution of coal by wood charcoal or other types of biomass for the production of metallurgical coke is catching the attention of the steelmaking industry worldwide because it generates less CO2 in the industrial processes. The objective of this paper is to correlate the effect of the proportion of coal and wood charcoal on the mechanical strength and CO2 reactivity in briquettes of mixtures of coal and wood charcoal. The briquettes were manufactured from mixtures of coal and 5, 10, 15, 20, 30, 40 or 50 wt-% of wood charcoal. Both materials were grounded and sieved until the particle size was less than 0.044 mm. The mixture was then pressed in a cylindrical die and heat-treated under a nitrogen flow from ambient temperature until 1373 K for 8 hours. Compressive strength and CO2 reactivity tests were conducted on the samples. Optimal results of the compressive strength were obtained for additions of wood charcoal between 10 and 15 wt-%. For mixtures with wood charcoal contents above... |
