Abstract
Biocoke has the potential to reduce the fossil-based materials in metallurgical processes, along with mitigating anthropogenic CO2- and greenhouse gas (GHG) emissions. Reducing those emissions is possible by using bio-based carbon, which is CO2-neutral, as a partial replacement of fossil carbon. In this paper, the effect of adding 5, 10, 15, 30, and 45 wt.% biomass pellets on the reactivity, the physicomechanical, and electrical properties of biocoke was established to assess the possibility of using it as a fuel and reducing agent for a blast furnace (BF) or as a carbon source in a submerged arc furnace (SAF). Biocoke was obtained under laboratory conditions at final coking temperatures of 950 or 1100 °C. Research results indicate that for BF purposes, 5 wt.% biomass additives are the maximum as the reactivity increases and the strength after reaction with CO2 decreases. On the other hand, biocoke’s physicomechanical and electrical properties, obtained at a carbonization temperature of 950 °C, can be considered a promising option for the SAF.
Highlights
The metallurgical industry is one of the most energy-intensive industrial sectors and is responsible for significant anthropogenic greenhouse gas (GHG) and CO2 emissions [1,2,3]
Achieving global goals to reduce anthropogenic GHG emissions is impossible without using alternative sources [6,7]
5–10% of anthropogenic CO2 emissions are from metallurgical production
Summary
The metallurgical industry is one of the most energy-intensive industrial sectors and is responsible for significant anthropogenic GHG and CO2 emissions [1,2,3]. Each process requires a heat and carbon source for carbothermal reduction. Using fossil-based materials as energy and carbon sources may have technological advantages [4,5]. Achieving global goals to reduce anthropogenic GHG emissions is impossible without using alternative sources [6,7]. 5–10% of anthropogenic CO2 emissions are from metallurgical production Most of these emissions come from smelting furnaces such as BF, EAF, and SAF [8]. This is due to their reliance on metallurgical coke [9,10,11]
