Filed: 2020-09-09
Abstract: The present invention is a technology for removing 90% or more of chlorine by subjecting oil fractions high in Cl to a high-temperature treatment using a solid acid catalyst. The oil fractions from which Cl has been removed can be introduced into a refinery process and converted into fuel or chemical products. In the present invention, chlorine can be removed through a heat treatment at a high temperature after the solid acid catalyst and the oil fractions high in Cl content are mixed. In the process of removing Cl, major impurities such as S, N, and O, as well as Na, Ca, Fe, and the like, which can act as catalyst poisons in catalytic reactions of the refinery process, are simultaneously removed. In the process of removing Cl from oil fractions high in Cl through the solid acid material, an average molecular weight of an oil fraction composition is slightly increased through oligomerization and alkylation reactions, such that abnormal reaction, deterioration of product properties, and yield loss can be prevented. The present invention enables, through a simple treatment, waste solid acid materials (waste zeolite, clay waste, etc.) discarded after being used in petrochemical processes to be usable as a solid acid catalyst material for Cl removal, and thus is environmentally advantageous.
