| Abstract: |
| Nickel monoxide was chloridized with hydrogen chloride as chlorinating agent produced by thermal pyrolysis of PVC at temperature of 673 K below in Ar atmosphere by heating the homogeneous mixture of PVC and nickel oxide with mass ratio of 10︰1. Reactivity of NiO was activated by roasting NiO in air to improve chlorination ratio of NiO from 35% to 95%. The results suggest that PVC is capable of chloridizing nickel oxide at low temperatures. The kinetics was investigated by heating the mixture at constant heating rate ranging from 10 to 40 K/min with TG-DTA. Apparent activation energy is 96 kJ/mol for PVC NiO, slightly lower than that of 114 kJ/mol for pure PVC by applying non-isothermal kinetic model. |
