摘要： The present disclosure provides a process for effectively separating and removing by-products (light gas, C5-C6 hydrocarbon oil fraction, polyethylbenzene) contained in a substantial amount in addition to ethylbenzene as a target compound in an alkylation reaction product of a fluidized catalytic cracking off-gas to prepare ethylbenzene having high purity, and process economical efficiency may be secured by utilizing the polyethylbenzene as an absorbent or gasoline fraction, without requiring a transalkylation reaction for further producing ethylbenzene from polyethylbenzene.

摘要： Disclosed are a process and system that are capable of performing selective hydrogenation on aromatic fractions by configuring a catalyst bed through staged loading of a plurality of hydrogenation catalysts with different catalytic properties, or configuring a catalyst system in which a plurality of hydrogenation catalysts are arranged using a plurality of reactors in such a way as to be equivalent with the staged loading, and as a result, are capable of suppressing aromatic loss while improving the selective removal of unsaturated hydrocarbons in the aromatic fraction and durability compared to the case of using a single catalyst.

摘要： Disclosed are a catalyst and a preparation method therefor, the catalyst being able to maintain a high production yield of C8 aromatic hydrocarbons in the process of converting a feedstock containing alkyl aromatics to C8 aromatic hydrocarbons such as mixed xylene through disproportionation/transalkylation/dealkylation while reducing a content of ethylbenzene in the products.
