Abstract

Domestic coal industry has started the sharp downturn since 1989, after the coal industry promotion,but the R&D budget of advanced countries including Japan has continuously increased in the field of clean coal development technologies. We investigated to analyze a world technological level in field of clean coal technology in order to compare the level of Korea with other countries, and this study analyzed 12,265 clean coal technology patents applied between 1970 and 2008 in USA, Europe, Japan, and Korea. The clean coal technologies could be classified into 9 major technologies. The gasification and liquefaction has the most shares of 30%, then the stabilization and drying is 18%, and the power plant is 13%. The separation and preparation has a very low share. Nevertheless, the analyzed result in this study has indicated the commercial spin-offs of the separation and preparation technology has the strongest technologies. Therefore, the technologies for the separation and preparation based on accumulated clean coal technologies need to be developed to increase self-development ratio of energy resources.

Patent Analysis

국내 석탄관련 산업은 1989년 석탄합리화사업 이후 침체되기 시작하였지만, 일본 등 선진국들은 청정석탄 기술개발을 위해 지속적인 연구개발을 수행하였다. 본 연구에서는 청정석탄개발기술에 관한 기술수준을특허정보 분석을 통하여 관련기술의 기술동향을 알아보고자 하였으며, 1970년 1월부터 2008년 12월까지 미국,유럽, 일본, 한국에서 출원된 특허출원 건수를 조사한 결과 총 12,265건으로 나타났다. 기술별로는 석탄화학/가스화/액화 분야가 30%로 가장 많았으며, 석탄회 분야가 19%, 개질 및 건조 분야 18%, 발전 분야 13%의 순으로 나타났으며, 선탄 및 선별관련 기술들의 특허점유율은 매우 낮게 나타났다. 최근 기술흐름을 주도하고 있는석탄의 연소효율 향상기술 및 석탄의 가스화 기술 등의 선진화를 이루기 위해서는 가장 근본이 되는 석탄 그자체를 선탄, 선별하고 처리하는 기술의 개발이 동시에 수반되어야 할 것으로 판단된다.
