Abstract:
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.

Claim (Index 4):
The method of  claim 1 , further comprising:\n feeding the quencher overhead stream to an absorption tower, absorbing the heavy oil fraction by an absorbent to be recovered to an absorption tower bottom stream, and mixing with the quencher bottom stream.
