Abstract Scope |
Polycyclic aromatic hydrocarbons (PAHs) represent a large group of compounds containing two or more fused six-membered rings. As air pollutants, they can spread over very long distances and are therefore internationally regulated. Metal producers use carbon materials as reducing agents, electrodes, lining materials, etc. As a consequence, they emit PAHs to varying degrees. Our goal is to develop a method for assessing and predicting PAH emissions from different carbon-based materials and increasing the fundamental knowledge about PAH formation and decomposition during various process conditions. Method development involves designing a setup for laboratory-scale experiments involving the use of two different furnace set-ups with instrumentation for off-gas analysis in order to examine the influence of process parameters such as temperature and gas atmosphere on the PAHs emission from carbon materials used in industrial processes. Analysis results for PAH 16 vs PAH 42 in two different laboratories were also compared. |
