Abstract (en)
[origin: EP4105299A1] Provided is a technology of removing 90% or more chlorine by treating an oil fraction having a high Cl content at a high temperature using a solid acid catalyst. The dechlorinated oil fraction may be introduced to a refinery process and converted into a fuel or a chemical product.In the presentembodiment, the solid acid catalyst and the oil fraction having a high Cl content are mixed and then chlorine is removed by a heat treatment at a high temperature. Main impurities such as S, N, and O and Na, Ca, Fe, and the like which may act as a catalyst poison in the catalyst reactions of a refinery process are removed simultaneously with the process of removing Cl.By the treatment at a high temperature in a process of removing Cl in an oil fraction having a high Cl content by the solid acid material, a reduction effect of Cl and N, S, O, and metal impurities may be increased.Since a waste solid acid material (waste zeolite, waste clay, and the like) which is discarded after use in a petrochemical process may be used as a solid acid material for Cl removal by a simple treatment, it is preferred from an environmental point of view.
