Pyrometallurgical processes in the iron and steel industry are energy intensive. Therefore, sustainability in terms of CO2 emissions is highly dependent on the choice of fuel. Large quantities of carbon are used in pyrometallurgical processes, for ex

This work focuses on the properties of hydrolysis lignin biocarbons with a perspective on utilizing the biocarbons in pyrometallurgical processes. Even if the blast furnace and basic oxygen furnace (BF-BOF) process route was replaced by emerging tech

Summary In this work gasification of different types of coke (higher quality and lower quality) were subjected with two different gas-atmosphere profiles (H₂-H₂O-CO-CO₂-N₂ and CO-CO2-N2) simulating Blast Furnace circumstances. It was found ou

Blast furnace is the most used process for production of pig iron in the world. It is charged mainly with metallurgical coke and ferrous materials such as pellets and/or sinter. When descending inside the blast furnace, iron bearing materials start t

Carbonaceous reductants for pyrometallurgical applications are usually obtained from fossil-based sources. The most important properties of the reductants greatly depend on the application and the feeding of the reductant into the process. However, t
