Abstract

As crude oil with heavier and/or highly oxidized components prevails, purification technologies such as desulfurization, denitrilization and demetalization have become important issues to control contents of sulfur and other impurities affecting the quality of petroleum. Also, the importance of catalyst technologies related with crude oil purification has been emphasized to control the production and yield of products. In this paper, technology trends of impurity removal such as sulfur, nitrogen and metal components from crude oil and catalysts related with purification of crude oil were studied through patent analysis. The patents published or registered in Korea, U. S. A., Japan, and Europe from mid 1970's to 2009 had been analyzed based on the application tendency, the distribution of major applicants, and their active indices, etc. The technology flow was figured out to see the technology trends.

우리가 사용하는 원유는 점점 중질화 되고 산도가 높아지고 있다. 석유의 품질에 영향을 미치는 유황의 함량을 조절하고, 오염금속을 제거하기 위하여 탈황, 탈질, 탈금속 등 불순물 제거기술의 중요성이 커지고 있으며 제품의 생산량과 수율을 조절하기 위한 정제 관련 촉매기술의 중요성 역시 증대하고 있다. 본 논문에서는 원유에서 황, 질소, 금속성분 등을 제거하는 기술과 원유의 정제와 관련된 촉매 기술에 대하여 한국, 미국, 일본, 유럽 등을 중심으로 1970년대 중반부터 2009년까지의 특허를 조사하고, 각국의 출원현황, 점유율, 주요출원인, 특허활동지수 등을 분석하였다. 또한, 주요 기술 분야에 대한 기술흐름도를 작성하여 기술 동향을 살펴보았다.
