초록

화력발전소 석탄재는 2010년을 기준으로 약 850만톤, 연탄재는 약 74만톤 배출된다. 이는 대량 재활용되지 않아 경제적, 환경적으로 부담이 되고 있는 실정이므로, 석탄 연소부산물의 자원화기술개발이 시급하다. 석탄 연소부산물을 균질하게 가공하는 분쇄 및 선별 등의 자원처리기술을 적용하고, 석탄 연소부산물의 품질을 관리하여, 비소성 그린시멘트인 지오폴리머의 원료로 재활용하고자 본 연구에서는 석탄 연소부산물의 지오폴리머 원료화 기술에 대한 특허와 논문을 분석하였다. 분석범위는 1979년 ~ 2013년까지의 미국, 유럽연합, 일본, 한국의 등록/공개된 특허와 SCI 논문으로 제한하였다. 특허와 논문은 키워드를 사용하여 수집하였으며, 기술의 정의에 의해 필터링하였다. 특허와 논문의 동향은 연도, 국가, 기업, 기술 등에 따라 분석하여 고찰하였다.

Approximately 8.5 million tons of fly ash and 740,000 tons of briquette ash were produced in 2010. Inefficient recycling of coal ash has been a heavy economic and environmental burden and economical coal ash utilization technologies are required to turn coal ash into valuable resources. In this study the patents and literature were analyzed to understand the present situation of coal ash recycling technologies and to promote utilization of coal ash for producing a non-sintering green cement, geopolymer. The survey was based on the open patents of USA, European Union, Japan and Korea, and the papers in SCI - indexed journals published between 1979 and 2013. Technical key words were used for data collection and noise filtering. Trends of recycling technologies in utilization of coal ash for producing geopolymers were discussed in terms of time periods, countries, companies and various forms of technologies.
