Description
Technical field
The present invention relates to a kind of hydrogenation catalysts and preparation method thereof, specifically a kind of to be applied to be hydrocracked, add
Hydrogen modify and the processes such as hydroisomerizing by hydrogenation catalyst that MCM-22 molecular sieves and Y molecular sieve mixture are acid constituent element and
Preparation method.
Background technology
Important manufacturing process of the hydrocracking technology as heavy oil lighting, low grade oils modification and Integrated Refinery And Petrochemical, tool
Have the advantages that production decision is flexible, adaptability to raw material is strong, purpose product selectivity is high, high-quality and tail oil added value is high.Add hydrogen
Cracking catalyst is the core of hydrocracking technology, therefore development, the development and application of hydrocracking catalyst are also that hydrogen is added to split
Change the main contents of technological progress.Hydrocracking catalyst is typical bifunctional catalyst, and catalyst carrier material offer is split
Change function, open loop is substantially carried out on acidic site, n-alkane is hydrocracked, the de- reactions such as alkyl, isomerization.At present, for
The active metal component understanding of the mechanism of action and its load technology of preparing on a support material in hydrocracking catalyst show
It has been mature on the whole with perfect, and the novel carriers material with more dominance energy also just becomes grinding for hydrocracking catalyst technology
Heat generating spot.
VGO feedstock is mainly made of saturated hydrocarbons, aromatic hydrocarbons and colloid etc..The polycyclic cyclic hydrocarbon molecules for making diameter big are with urging
Change activated centre contact, it is necessary that catalyst has good pore structure.Hydrocracking catalyst only have big aperture,
Macropore holds, pore size distribution is uniform, pore system is open and the pore structures feature such as unimpeded, and the polycyclic hydrocarbon molecule that can just make diameter big compares
Catalyst duct is easily accessible, increases the chance for contacting and reacting with activated centre, improves ring-opening reaction speed;Diameter is small
Chain hydrocarbon can then be easier to be detached from from duct, diffuse out, and reduce chain-breaking reaction speed.The acidity and pore structure of catalysis material
It is the principal element for determining hydrocracking catalyst.
Y types and Beta types molecular sieve are due to twelve-ring macroporous structure, being widely used in hydrocracking catalyst
As acid centre.Y type molecular sieve has the characteristics that three-dimensional supercage, tetrahedron trend and twelve-ring macroporous structure, has higher
Segmented ring performance, mostly suitable for light oil type hydrogen cracking catalyst.Beta type molecular sieves are twelve-ring macropore straight channels
Structure, it is preferable for straight-chain hydrocarbons stereoselectivity, mostly suitable in middle oil type hydrocracking catalyst.In recent years, gasoline demand
Steady-state growth is measured, the growth of diesel oil demand is slower, and the development of diesel oil substitute fuel technology, diesel and gasoline ratio persistently reduce in addition, it is contemplated that
The year two thousand twenty is down to 1.0 or so.And aviation kerosine was increased speed very fast in recent years, annual growth 9.7%.In addition, ethylene and virtue
Hydrocarbon demand sustainable growth, but the deficiency of the raw material degree of self-sufficiency limits its development.Changed according to diesel and gasoline ratio, mobile type, which is hydrocracked, urges
The exploitation of agent has great importance.MCM-22 molecular sieves have MWW structures, there is unique 10 membered ring channel and 12 yuan of annular distances
Cave structure shows good catalytic performance in the reactions such as alkylation, toluene disproportionation, xylene isomerization.
CN201511028094.4 discloses a kind of high-precision desulphurization and denitrification catalyst carrier, by MCM-22 molecular sieves and oxidation
Magnesium, Si oxide and aluminum oxide are mixed with and obtain.Load C o, Mo, Ni, W metal, using naphtha as raw material, in 250-350
Prepared catalyst is evaluated under the conditions of DEG C, as a result shows prepared catalyst desulfurizing rate up to more than 92%, denitrogenation
Rate is horizontal higher than the desulfurization removing nitric of contrast medium up to more than 35%.
CN200910012945.4 discloses a kind of metal supported MCM-22 molecular sieve hollow sphere bifunctional catalyst system
Preparation Method using MCM-22 as the supported on carriers metal Mo of acid constituent element, for oxygen-free dehydrogenating aromatization of methane aromatic hydrocarbons, has
