【 摘 要 】

The iron and steel industry needs for every ton of finished steel product a minimum of 250 kg of fossil coke. A CO2-neutral substitute of coke is biocoke to improve the carbon footprint of iron and steelmaking industry. Unused woody and straw-like biomass residue can be agglomerated to briquettes and using a pyrolysis technique transformed to biocoke. Objective of this study was the production and analysis of this biocoke regarding its possible use within the blast furnace by applying various pyrolysis temperatures of 200, 350, and 500 °C. Physical (mechanical strength) and chemical fuel qualities (proximate analysis, ultimate analysis, and calorific value) were investigated. It is asserted that with a rise in the pyrolysis temperature the physical fuel qualities are negative and the chemical ones positive effected. None of the used temperatures created a biocoke that can entire substitute the hitherto in the metallurgical industry used fossil coke with all its characteristics. Nevertheless, extensive knowledge about the behavior of various fuel qualities while rising the pyrolysis temperature was gained.
