Method for Removing Chlorine from High Chlorine Content Waste Oil Using Solid Acid Substances

Abstract

The present embodiment pertains to a technique for removing at least 90% of the chlorine in high Cl content oil by performing a high-temperature treatment using solid acid substances. The oil removed Cl from a waste oil can be incorporated in a refinery process and thereby converted into fuel or a chemical product. Chlorine can be removed through a high-temperature heat treatment after mixing high Cl content oil with a solid acid material. In the process of removing Cl, major impurities, such as S, N, and O, as well as Na, Ca, and Fe, which can act as catalyst poisons in the catalytic reactions of a refinery process, are also removed at the same time.
