Abstract: 
Injecting auxiliary reducing agents (ARAs) in the raceway zone of a blast furnace increases the efficiency and reduces CO2 emissions in case using bio-based sources. Reliable conversion rates are crucial to identify new ARAs or their mixtures and to optimize the ARA injection process, but they are hardly available in literature. The harsh reaction conditions in blast furnaces require suitable experimental equipment to determine reliable conversion rates. In this work a novel entrained flow reactor for evaluating ARAs will be presented and compared to the reaction conditions in a blast furnace. Furthermore, first experimental results will be presented.
