Abstract
Provided are an apparatus and a method for refining pyrolysis oil in which a dechlorination reaction is performed under a first hydrotreating catalyst. Hydrogen chloride as a by-product is removed, and then a denitrification reaction is performed under a second hydrotreating catalyst, thereby preventing production of an ammonium salt (NHCl), and providing refined oil. It is excellent in prevention of corrosion of a reactor, improvement of durability, occurrence of differential pressure, process efficiency, has very low contents of impurities such as chlorine, nitrogen, and metal and olefin, and has excellent quality.
