Abstract
<p>It is thought that the one of nitrile butadiene rubber glove recycling method is liquefaction by pyrolysis. While, because the main component of pyrolysis residue (NBR residue) is carbon, NBR residue is expected to be used as solid fuel by removing oxygen and hydrogen by heat treatment. In this study, the carbonization degree and hygroscopicity of NBR residue were evaluated after heat treating at 500, 600, 700, 800 and 900 oC. As a result, carbon weight ratio was almost unchanged by heat treatment. Whereas, oxygen weight ratio was highest when NBR residue was heat treated at 700 oC. However, over 800 oC, it was decreased with increasing the temperature. In addition, hydrogen weight ratio was decreased with increasing the temperature. Therefore, it was suggested that demethylation and dehydration was caused below 700 oC, and decarbonization was also caused over 800 oC. On the other hand, the hygroscopicity of NBR residue was decreased by heat treatment over 800 oC. These results suggested that NBR residue heat treated over 800 oC could be more useful as solid fuel.</p>
