Abstract

Chemical catalyst products are applied to various fields such as petrochemical process, air pollution prevention facility and automobile exhaust gas purifier. The domestic and overseas chemical catalyst market is increasing every year, and the amount of waste catalyst generated thereby is also increasing. Most of the used chemical catalyst products, such as desulfurized waste catalysts and automobile waste catalysts containing valuable metals are important recyclable resources from a substitute resource point of view. The recycling processes for recovering valuable metals have been commercialized through some urban mining companies, and SCR denitration catalysts have been recycled through some remanufacturing companies. In this paper, the amount of domestic production and recycling of major catalyst products have thus been investigated and analyzed so as to be used as basic data for establishing industrial support policy for recycling of used chemical catalyst products. Also tasks for promoting the recycling of used chemical catalyst products are suggested.

화학촉매제품은 석유화학공정, 대기오염방지시설, 자동차 배기가스 정화 장치 등 다양한 분야에 적용되고 있다. 국내외 화학촉매 시장은 매년 증가하고 있는 추세이며, 그에 따라 발생되는 폐촉매량도 증가하고 있다. 탈황 폐촉매, 자동차 폐촉매 등 대부분의 사용 후 화학촉매제품은 유가금속을 함유하고 있어 경제적 가치와 자원 확보 측면에서 매우 중요한 순환자원이다. 이에 일부 도시광산업체를 통해 유가금속을 회수하는 재자원화 공정이 상용화 되어 있고, 사용 후 SCR 탈질 촉매제품은 일부 재제조를 통해 자원순환되고 있다. 이에 본 논문에서는 사용 후 화학촉매제품의 재자원화 산업 지원 정책 수립의 기초자료로 활용이 가능하도록 주요촉매제품별 국내 발생량 및 재자원화 현황을 조사 분석하였으며, 사용 후 화학촉매제품의 자원순환 활성화를 위한 발전과제를 제시하였다.
