Abstract
The present invention relates to a kind of heavy aromatics lightening catalyst, mainly solve to exist in the prior art that fused ring compound hydrogenation selectivity is not high, the high problem of mononuclear aromatics loss late.The present invention passes through a kind of condensed-nuclei aromatics selective hydrocatalyst, it include: containing nonacid or faintly acid porous carrier, and at least two metallic elements or compound selected from VIII, III B of load thereon, the metallic element or compound are in the technical solution of nuclear shell distribution on the surface of the carrier, significantly improve fused ring compound hydrogenation selectivity.
Description
Technical field
The present invention relates to a kind of heavy aromatics lightening catalysts and preparation method thereof.
Background technique
Condensed-nuclei aromatics refers to bicyclic and multiring structure aromatic component, be largely present in catalytic cracking, ethylene bottom oil and
The processes such as PX production, it is most of by as diesel oil blending component if catalytic cracking light cycle oil annual output is more than 10,000,000.Closely
As the situation that supply falls short of demand is presented in the continuous increase of China's PX demand, PX over year, realize Aromatic Hydrocarbon United Plant enlargement and
Raw material diversification is to solve the problems, such as one of the key factor of current PX industrial production.Therefore, Aromatic Hydrocarbon United Plant pair is made full use of
Produce condensed-nuclei aromatics, the condensed-nuclei aromatics of research and utilization oil refining apparatus by-product is of great significance to produce light aromatics.From reacting
From the point of view of journey, realize conversion most critical from condensed-nuclei aromatics to mononuclear aromatics the step of be realize condensed-nuclei aromatics selective hydrogenation, general
Polycyclic aromatic hydrocarbon partial hydrogenation generates mononuclear aromatics component.It is coexisted in system in monocycle and polycyclic aromatic hydrocarbon, realizes that arenes selectivity adds
Hydrogen is the significant process for improving mononuclear aromatics yield.The metals such as noble metal platinum, palladium and base metal molybdenum, nickel have been reported for more
Cycloaromatics adds hydrogen saturation.
