Description

A kind of preparation method of hydrotreating catalyst
Technical field
The present invention relates to a kind of preparation method of hydrotreating catalyst, is especially suitable for heavy distillate hydrogenation de- The preparation method of nitrogen, the hydrotreating catalyst of sweetening process.
Background technology
Content containing nitrogen, sulphur, oxygen and metal impurities in crude oil is continuously increased, and crude oil degree of heaviness is constantly deepened, Pendulum is come true in face of people, and the presence of these impurity not only makes catalyst poisoning in subsequent processes, but also meeting The pernicious gases such as substantial amounts of sulfur and nitrogen oxides are given off, the health of the mankind and the protection of environment is injured.Using work Property the high, catalyst of good stability relax can not only process conditions, moreover it is possible to reduce hydrogen consumption, reach energy-saving effect.
Hydroprocessing processes be exactly with containing the VIIIth race in periodic table and group VIB it is metal oxide supported to refractory without In machine porous material, typically using aluminum oxide, silica, titanium dioxide, carborundum, boron oxide, zirconium oxide and their combinations Composite carrier together.By dipping process, catalyst precarsor is prepared, then through the drying and roasting of some steps Operation prepares finished catalyst.Finished catalyst is containing hydrogen sulfide, sulfur-bearing organic compound using presulfurization is front carried out In the presence of thing or elemental sulfur, oxidized catalyst is set to change into sulphided state catalyst.
The purpose of weighted BMO spaces is to remove the impurity such as nitrogen, sulphur, oxygen in feedstock oil, the quality and quantity of intermediate oil All increased.For example, it is hydrocracked and is required for pre-processing feedstock oil with hydroforming reaction, prevents miscellaneous in crude oil Matter makes catalyst poisoning, and catalyst is once be poisoned, and the loss for causing is inestimable.So, hydroprocessing processes are oil refining process In one of indispensable and particularly significant step.It is known in the art, without the activearm of calcined catalyst Divide dispersiveness high, weaker model ylid bloom action power is only existed between active metal and carrier, therefore it is anti-to effectively improve catalyst Should activity.High activity, the development of the catalyst of high stability are always the bottleneck of this area institute Gonna breakthrough, industrial using high living Property, high stability catalyst not only can voluminous target product, and reaction can also be made to carry out under conditions of relatively relaxing, transport Turn cycle stretch-out, reduce production cost.
This area is done a lot of work in terms of activity of hydrocatalyst is improved, and many documents have been reported, and are achieved Great success, is that later research and development are laid a good foundation.CN 85103891 describes the preparation method of hydrogenation conversion catalyst.Should Method is that phosphorus containg substances and soluble amine compound are separately added into maceration extract, and two kinds of solution is admixed together to be impregnated, And need to adjust the pH value of maceration extract and the temperature of dipping solution in dipping process.The method prepares catalyst process condition and answers Miscellaneous, ammonium hydroxide has ammonia to release in course of dissolution, and harmful to environment, denitrification effect is not obvious, is difficult industrialized production.
Chinese patent CN 101590416A describe the preparation method of molybdenum-nickel hydrogenation catalyst, the method be using kneading ~ Two steps of dipping are prepared catalyst, first under conditions of nitric acid presence, by molybdenum oxide, titanium-containing compound, containing phosphatization Compound and aluminum oxide Jing kneadings, extruded moulding, dry, roasting obtains the aluminum oxide article shaped of titaniferous, phosphorus, molybdenum, then impregnates nickeliferous Phosphoric acid solution, obtain molybdenum-nickel hydrogenation catalyst after drying, roasting.Chinese patent CN 1052501A disclose hydrogenation and urge The preparation method of agent.The method is added in the maceration extract containing the metals of Co-W-Mo tri- and helped to improve the activity of catalyst Agent P, F, B, using segmentation impregnation, after drying, roasting finished catalyst are obtained.Said method is lived in dip loading Property metal after through high-temperature roasting, active metal component is stronger with the active force of carrier, affect catalyst cure efficiency, and And also assemble can amount of activated metal component, the decentralization of active metal is affected, and then affect the activity of catalyst.
In Japan Patent JP11033412, a kind of method for preparing load type metal catalyst is disclosed.The method is by gold The aqueous solution of category salt and surfactant is added in porous media material, and room temperature lower section is put more than 1 hour, and ultrasonic wave is used afterwards Process the maceration extract 2 hours, it is ultrasonically treated after, the porous media material after this is impregnated was in 120 DEG C of dryings 12 hours Roasting 2 hours, obtains finished catalyst under 500 DEG C of air atmospheres.The method preparation catalyst process engineering is loaded down with trivial details, and activity is low, It is unsuitable for industrial mass production.
Japan Patent JP 04 ~ 166231 describes a kind of hydrogenation catalyst preparation method.The method is soaked using substep Stain, carrier first with phosphorous active metal component solution impregnation after, be dried at room temperature ~ 200 DEG C, impregnated carrier after being dried Contact with polyol solution, passing below 200 DEG C of dryings, obtain finished catalyst.United States Patent (USP) US 6281333 Disclose a kind of preparation method of hydrotreating catalyst.The carrier loaded active metal maceration extract containing volatile organic components, no Catalyst is obtained through roasting, in above-mentioned catalyst preparation process, organic additive is added in maceration extract, the catalyst Jing rooms after dipping Temperature ageing is some as a child, is dried process.There is metal precipitating, color blackening phenomena in dried catalyst surface, and And have a large amount of dust to occur in catalyst surface.So both have impact on high degree of dispersion of the active component in carrier surface, and to urging Agent brings adverse effect during later stage filling, directly affects the reactivity of catalyst.
