C9 Catalyst for preparing xylene mixture from benzene toluene and C9 or more aromatic compounds and the preparation method thereof

摘要

The present invention relates to a catalyst for preparing mixed xylene through disproportionation / transalkylation reaction from benzene, toluene and C9 or more aromatic compounds, and a method for preparing the same. Mordenite or beta (β) type zeolites having a molar ratio of 20 to 200, inorganic binders such as alumina, platinum (Pt) / tin (Sn), platinum / lead (Pb), and platinum It relates to a catalyst consisting of a metal selected from the group consisting of / indium (In) and a method for producing the same. As a result of the disproportionation / transalkylation of benzene, toluene and C9 or more aromatic compounds using the catalyst prepared according to the present invention, the catalyst of the present invention has a higher yield of mixed xylenes compared to the prior art, and the catalyst is deactivated. Speed also has a significant effect.
