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.
