HYDROCRACKING CATALYST FOR PREPARING LIGHT AROMATIC HYDROCARBON, METHOD FOR PREPARING SAME AND METHOD FOR PREPARING LIGHT AROMATIC HYDROCARBON BY USING SAME
Publication/Patent Number: US2019284111A1 Publication Date: 2019-09-19 Application Number: 16/345,085 Filing Date: 2016-10-27 Inventor: Lee, Jung Kyoo   Shin, Jaeuk   Choi, Yeseul   Chang, Soon Cheol   Kang, Heung Jung   Kang, Dong Il   Assignee: S-OIL CORPORATION   DONG-A UNIVERSITY RESEARCH FOUNDATION FOR INDUSTRY-ACADEMY COOPERATION   IPC: C07C4/18 Abstract: The present disclosure relates to a hydrocracking catalyst for preparing a C6-C9 light aromatic hydrocarbons having an increased BTX content from a polycyclic aromatic hydrocarbon, a method for preparing the same and a method for preparing a C6-C9 light aromatic hydrocarbons having an increased BTX content by using the same. More specifically, an effect of obtaining a C6-C9 light aromatic hydrocarbons having an increased BTX content with a high yield from the byproducts of oil refining and petrochemical processes, which contain polycyclic aromatic hydrocarbons such as naphthalene, alkylnaphthalene, etc., can be achieved by using a catalyst in which one or more metal selected from group VIII and one or more metal selected from group VIB are supported on a composite zeolite support of zeolite beta and zeolite ZSM-5.
