Abstract

The influences of Ca and Fe based oxides as dechlorination sorbents on the product distribution, boiling point distribution of liquid product, concentration of Cl of the products from the pyrolysis of PVC containing combustible wastes were investigated. With Fe based oxides as the sorbents, the yield of liquid product remarkably decreased whereas the decrease of the boiling point distribution of the liquid product was not noticeable. This phenomenon indicated that Fe based oxides worked as catalysts with weak catalytic activity. With Ca based oxides as the sorbents, the yield of liquid product did not decrease and the boiling point distribution of liquid product did not change significantly, but the dechlorination performance of these was much better than that with Fe based oxides.

PVC 함유 가연성폐기물의 열분해시 Ca 계열 및 Fe 계열 산화물을 탈염 흡수제로 사용하여 생성물의 분포, 액상 생성물의 비점분포, 생성물의 염소 농도에 미치는 영향을 조사하였다. Fe 계열 산화물 분말을 액상에서 흡수제로 사용시 오일의 수율이 뚜렷하게 감소하였다. 이러한 현상은 산화철이 열분해시 일부 열분해 촉매의 역할을 하였을 가능성을 나타낸다. 반면에 오일의 비점분포가 낮아지는 현상은 발견되지 않았으며 이러한 현상은 산화철의 촉매 반응성이 크지 않기 때문으로 보인다. Ca 계열 산화물 분말을 흡수제로 사용한 경우 오일 수율이 감소하는 현상은 발견되지 않았으며 비점분포도 큰 변화가 없었으나 탈염성능이 산화철 분말 흡수제 보다 더 우수하였다.
