ABSTRACT

An increase in steel production causes an increase in the use of carbon fuels and reducing agents, which in turn leads to greenhouse gas emissions. It is possible to reduce the environmental impact without compromising the quality of metallurgical products through the use of renewable carbon materials. In this paper, the applicability of biocoke production for various metallurgical processes has been considered. The fuels and reducing agents required in the main metallurgical industries are specified and the practice of adding biomass to a coal blend for coking is presented. The current biomass application to producing fuel and reducing agents in coal blends reveals their real potential for obtaining products of the required quality. The use of biomass as a component of coal blends is most effective when it is in a compressed or preliminary carbonised form. The outlined critical review is the base for conducting research on the production of biocoke using various biomass additives. The most promising sources for biocoke production are found to be biomass pellets.

摘要

钢铁产量的增加导致碳燃料和还原剂的使用增加，进而导致温室气体排放。通过使用可再生碳材料，可以在不损害冶金产品质量的情况下减少对环境的影响。在本文中，已经考虑了生物炭生产在各种冶金过程中的适用性。详细说明了主要冶金工业中需要的燃料和还原剂，并介绍了向煤共混物中添加生物质以进行焦化的方法。当前生物质在混合煤中生产燃料和还原剂的应用揭示了其获得所需质量产品的真正潜力。当生物质以压缩或初步碳化的形式使用时，将其作为煤掺混物的一种成分最为有效。概述的关键评审是进行研究使用各种生物质添加剂生产生物焦炭的基础。发现生物焦炭生产的最有希望的来源是生物质颗粒。
