    • This study aimed to examine the changes in the chemical forms of chlorine in coal during pyrolysis at 800 °C by using Cl K-edge X-ray absorption near-edge structure (XANES) spectroscopy. The char samples were prepared with a novel one-stage fluidising-bed quartz reactor at a fast heating rate. The samples were then collected and sealed in an argon-filled bag in order to minimise possible oxidation reactions. Both pyrolysis temperature and holding time can significantly affect the transformation of Cl, including the possible formation of chlorine-containing organic structures.
