Characterisation of Biochars for Metallurgical Applications and Means of Optimisation
Short Introductive summary
The metallurgical industry is responsible for a considerable share of the world’s CO2 emissions, thus appropriate mitigation strategies are urgently needed to reach global targets for Greenhouse gas (GHG) emission reductions. A significant share of these emissions is related to the use of coke or coal for the reduction and/or carburization of raw materials and for energy generation. The substitution of fossil C-carriers with sustainably produced biochar (BC) could be achieved without major adaptations to the processes and without high investment costs, making this option an interesting solution. The purpose of the work was the investigation of BC properties relevant for the use in metallurgical processes (e.g. C content, ash content, density, reactivity (CRI), specific surface etc.), their comparison with typical fossil C-carriers, requirements of specific metallurgical processes as well as the evaluation of possible means to improve certain BC properties for these processes. As a result of the presented work, advantages and disadvantages of BC compared to fossil C carriers, depending on their use, have been defined, which forms the basis for further R&D work on this topic.

Presenter's biography
I joined BIOS in 2001 and participated in many R&D and engineering projects as an project engineer and since 2005 also as an project manager. In recent years my focus was on the development of new pyrolysis technologies and the research of possibilities to substitue coal/coke with biochar.
