Generation of hydrogen from polyvinyl chloride by milling ...

Abstract. This work discusses an alternative process option for the treatment of polyvinyl chloride (PVC) by producing hydrogen (H (2)) gas, at the same time fixing chlorine for proper environmental control. In the first-stage, a milling operation is performed in a planetary ball mill to obtain a mixture of PVC sample with CaO and Ni (OH) (2 ...
