PRODUCTION OF VALUABLE AROMATICS AND OLEFINS FROM FCC LIGHT CYCLE OIL

摘要

PURPOSE: A method for manufacturing valuable aromatics and olefins from light cycle oil of a flowing layer catalytic cracking process is provided to produce aromatic products of high concentration such as benzene, toluene, and xylene from the light cycle oil of the flowing layer catalytic cracking process by substituting naphtha. CONSTITUTION: A method for manufacturing valuable aromatics and olefins from flowing layer catalytic cracking oil comprises: decomposing the LCO(light cycle oil)(1) which is produced from the flowing layer catalytic cracking process under the presence of a contact cracking catalyst; disuniting the discomposed component into a mixing aromatic component(5) including aromatic component, olefinic component, and two or more aromatic rings; saturating two or more aromatic rings by hydrogen- treating the mixing aromatic component under the presence of the catalyst; and recycling an outcome in order to be mixed with the LCO.
