Abstract
The invention relates to an application of a supported palladium catalyst in selective hydrogenation reaction, wherein the supported palladium catalyst takes Pd as an active component, a mesoporous molecular sieve MCM-41 as a carrier, and nanoparticles of the active component Pd are dispersed on the surface and/or orifices of the carrier. The research of the invention finds that: in the supported catalyst taking Pd as an active component and taking a mesoporous molecular sieve MCM-41 as a carrier, when nano particles of the active component Pd are dispersed on the surface and/or orifices of the carrier, the catalyst activity and/or selectivity are obviously superior to those of a Pd/MCM-41 catalyst without the characteristic, and the catalyst is particularly suitable for selective hydrogenation reaction of unsaturated hydrocarbons, alpha, beta-unsaturated aldehyde ketones and halogenated nitrobenzene compounds.
Description
Technical field
The present invention relates to a kind of application of load type palladium catalyst in selective hydrogenation, belong to heterogeneous catalysis technology
Field.
Background technology
Selection hydrogenation is a main kind of important reaction, occupies important in fields such as petrochemical industry, fine chemistry industry and pharmacy
Status.The noble metal catalyst of support type is the important selective hydrogenation catalyst of a class.Such as noble metal catalyst is in phenylacetylene
Selection hydrogenation (J.Mol.Catal.A, 2014,381:61-69), cinnamic acid selection hydrogenation (J.Catal., 2003,214:78-
87) and nitrohalogen compound selection hydrogenation aspect (J.Mol.Catal.A, 2009,308:Application 79-86) has a large amount of reports
Road.But noble metal hydrogenation hyperactivity, it is therefore desirable to use the distribution of control metal component, add auxiliary agent or reacting
" poisonous substance " is introduced in journey and suppresses the method modulation noble metal catalyst selective hydrogenation behaviors such as the activity or extent of reaction of catalyst.
CN102294269A discloses a kind of resistant to sulfur noble metal hydrogenation desulphurization catalyst, and catalyst disclosed in the case is with silicon
Alkanisation modified silica, silica-rich zeolite, MCM-41 or SBA-15 silicon-based mesoporous molecular sieve porous silica-base materials are used as load
Body, supports noble metal active component, and the case shows that the desulphurizing activated and stability of this kind of catalyst is significantly higher than without silanization
Modified catalyst, and cracking activity is significantly reduced, and shows good hydrodesulfurization performance.The case is not directed to this kind of urging
Application of the agent in selective dehydrogenation reaction.
The content of the invention
Present invention research finds to be urged as active component and using mesostructured material as the support type of carrier using Pd
Agent, when the nano particle of active component Pd is scattered in the surface and/or aperture of the carrier, with good catalysis activity
And/or selective hydrogenation activity, it is substantially better than the catalyst without this feature, example in terms of the conversion ratio and/or in terms of selectivity
Nano particle such as active component Pd is scattered in the Pd/MCM-41 catalyst inside mesopore orbit.
In view of studying above, the present invention provides a kind of application of load type palladium catalyst in selective hydrogenation, institute
It is using Pd as active component, using mesostructured material as carrier, and active component Pd to state load type palladium catalyst
Nano particle is scattered in the surface and/or aperture of the carrier.
