Abstract
The invention discloses a preparation method of an aniline hydrogenating amorphous nickel-aluminum catalyst. The preparation method of the aniline hydrogenating amorphous nickel-aluminum catalyst comprises the following steps: pretreating an alloy to crush the alloy; and putting the crushed alloy into a melting furnace for melting the alloy, pressing the melted alloy onto a copper roll from a spray nozzle on the lower part of the melting furnace through inert gas, quickly cooling, and throwing out from a tangent line of the copper roll to obtain an amorphous alloy. According to the preparation method, under the same condition, the amorphous alloy catalyst has high hydrogenating activity, relatively high magnetism and thermal stability, more active centers and better catalyzing effect in aniline hydrogenation.
Description
Technical field
The present invention relates to petrochemical industry, particularly relate to a kind of preparation method of aniline amorphous hydrogenating nickel-alumina catalyst.
Background technology
The microstructure of natural various materials can be divided into by the ordered state of its composed atom ordered structure and disordered structure two large classes.Crystal is typical ordered structure, and gas, liquid and non-crystalline solids belong to disordered structure.Wherein non-crystalline solids are a kind of metal or alloy solids that do not have the atom three-dimensional periodic to arrange, and it is arranged in the crystal lattice that surpasses beyond several atomic distance scopes, do not have a long-range order.The non-crystalline solids material comprises the types such as amorphous state inorganic material, amorphous polymer and amorphous alloy such as glass.
Compare with common crystalline state Metal and Alloy, amorphous metal and alloy have higher intensity, good magnetic performance and corrosion resistance etc., amorphous alloy can be used as catalyst, but at present the problem that faces of amorphous nickel catalyst mainly is the little and unstability of specific area.Amorphous alloy is a kind of material that is in inferior equilibrium state, has the trend that transforms to the equilibrium state crystal, and this unstability of amorphous alloy has limited its range of application, and can only use under lower temperature.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of preparation method of aniline amorphous hydrogenating nickel-alumina catalyst, the product excellent catalytic effect that the method makes.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of preparation method of aniline amorphous hydrogenating nickel-alumina catalyst is provided, comprises that step is:
(1) alloy is carried out preliminary treatment, make described alloy broken;
(2) alloy of described fragmentation is put in the melting furnace and melting, the alloy of described melting is pressed from the lower nozzle of described melting furnace by inert gas and is sprayed onto on the copper roller, and fast cooling and dish out along described copper roller tangent line obtains amorphous alloy.
In a preferred embodiment of the present invention, the size of described alloy fragmentation is 5-10mm.
In a preferred embodiment of the present invention, described inert gas is nitrogen, argon gas or hydrogen-argon-mixed body.
In a preferred embodiment of the present invention, described copper roller is connected with cooling water and High Rotation Speed.
The invention has the beneficial effects as follows: the preparation method of aniline amorphous hydrogenating nickel-alumina catalyst of the present invention, the hydrogenation activity of amorphous alloy catalyst is high under the equal conditions, amorphous alloy catalyst has magnetic, heat endurance is higher, amorphous alloy catalyst activated centre number is many, and better catalytic effect is arranged in the aniline hydrogenation reaction.
The specific embodiment
The below is described in detail preferred embodiment of the present invention, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
