Macropore proportion is more, is particularly suited for the carrier as hydrorefining catalyst for heavy oil.
CN200710179630.X discloses a kind of preparation method of nickel-coated alumina powder, and its feature exists
Suspension is made in the mixed liquor of the nano aluminium oxide by dispersant is added, stirring is lower to add nickel salt solution,
After stirring, ammoniacal liquor is instilled in mixed liquor, add distilled water, obtain the cooperation of navy blue nickel ammonia
Thing ([Ni (NH3)6]2+)-Aluminum oxide mixed solution C, then by hydrothermal aging, filter, wash, dry,
Obtain cladding product in the middle of green;Reduction roasting is carried out again, obtains black Ni-Coated alumina powder.
CN1102862C discloses a kind of nickel-containing hydrogenationcatalysts, contains:In terms of nickel oxide, 65-80%
Nickel, in terms of silica, the silicon of 10-25%, in terms of zirconium oxide, the zirconium of 2-10%, with aluminum oxide
Meter, the aluminium of 0-10%, its precondition is that the content sum of silica and aluminum oxide is at least 15% (weight
Amount %, based on the gross weight of catalyst), this catalyst be by by nickel, zirconium, if necessary,
The acidic aqueous solution of the also salt of aluminium is added to silicon, if necessary, the also alkaline water of the compound of aluminium
In solution or suspension, the pH of the mixture of such acquisition is reduced at least 6.5, then pass through into
One step is added alkaline solution and pH value regulation is arrived into 7-8, separates the solid of so deposition, is dried, is molded
And sinter what is obtained.In addition also disclose the method for preparing catalyst, and its prepare medicinal white oils,
The method of high-purity medical paraffin and low boiling low arene content or aromatic free hydrocarbon mixture.Should
The preparation method of catalyst is commonly used to prepare high-activity component content catalyst, but uses party's legal system
Standby catalyst activity is poor.
Article " the changes induced by calcination temperature in of Agudo A L etc.
hydrodesulfurization activity of NiCo-Mo/Al2O3Catalysis, Applied Catalysis,
1987,30:185-188 ", has investigated sintering temperature to NiCoMo/A12O3Catalyst rhohene desulfiirization is lived
The influence of property.Result shows that the desulphurizing activated of catalyst activated at 500 DEG C is significantly higher than 600
The catalyst activated under the conditions of DEG C, this is due to metal and aluminum oxide in the catalyst when activating for 600 DEG C
Spinel structure is generated there is strong interaction so as to cause catalyst activity to be remarkably decreased in carrier.Activation
Temperature is higher, and the nickel aluminate phase content of generation is higher, and the activity decrease of catalyst is more obvious.
“Influence of support-interaction on the sulfidation behavior and
hydrodesulfurization activity of Al2O3Support W, CoW and NiW model
Catalysts, J Phys Chem B, 2002,106:5897-5906 " equally draws similar conclusion.
Because nickel and alumina support can occur strong interaction generation spinelle knot in high-temperature calcination process
Structure, so as to cause catalyst activity to be remarkably decreased, therefore all cautiously made as far as possible before high-temperature roasting
With both, it is to avoid the generation of spinel structure.Because being generally required when preparing catalyst carrier with it
High-temperature roasting is carried out, people is suspected, so, rare nickeliferous plan thin water different from other metals
Aluminium stone is reported.
The catalyst with hydrogenation activity higher is prepared, corresponding active metal component content also will height.
Simple application infusion process prepares hydrotreating catalyst, it is necessary to prepare high activity metal constituent content
Solution carries out dipping to carrier and is obtained.Therefore there are the following problems in dipping process:(1) due to carrying
The water absorption rate of body is certain, using the maceration extract given volume of incipient impregnation method, active metal component
Addition is too high to cause dissolving incomplete;(2) prepare and need in catalyst process repeatedly dipping activity
Component, twice, three times even four times could be by the activity component impregnation of certain content to carrier, this
The problems such as having resulted in cumbersome preparation section, long preparation period, loss of active component;(3) repeatedly leaching
During stain, generally require to add organic or inorganic dispersant to increase active metal in maceration extract
The decentralization of component, but can there is removing in last handling process in these.
In the preparation process of catalyst carrier, by the compound containing active metal component with kneading
Form is introduced, and the compound for containing a certain amount of active metal component in shaping carrier is reached drop
The problem of the load difficulty run into low high content active metal component catalyst preparation process.But it is logical
Kneading method is crossed in the form of kneading by active metallic compound and aluminum hydroxide solid elastomer powder or alumina powder
Direct mixed-forming, the method has that brilliant mix particles are uneven and catalyst strength,
It is not easy to combine to form specific skeleton structure between simple kneading each component simultaneously.
