| Abstract;This paper explains the following items on the titled research: 1) Objectives; Recycling as carbon material of solid residue (I) obtained by thermal decomposition of chlorinated synthetic rubber, 2) approach; Thermal decomposition of chloroprene (CR), nitrile butadiene rubber/polyvinyl chloride blend (NBR/PVC) at maximum temperature of 800 .DEG.C., warming rate of 5 K/min., under nitrogen atmosphere to study the titled elements in I, 3) result in CR; More than 90% by weight of chlorine was converted to HCl gas and emissioned in vapor phase, while about 60% by weight of sulfur remained in I. Lead was mostly converted to chloride and isolated from I without remaining in I. and 4) result in NBR/PVC; A part of chlorine compounds was absorbed by co-present CaCO3 and remains in I. Sulfur compounds were emissioned as gas, while remained in I as CaS partially. |
