Description
Technical field
The invention belongs to the preparation field of aluminium colloidal sol, relating in particular to a kind of is that the preparation of aluminium source is low-cost, the novel process of high adhesion energy aluminium colloidal sol with multiple aluminum compound.
Background technology
Aluminium colloidal sol is widely used in the bonding of catalyzer as a kind of high temperature resistant and inorganic polymer binding agent that adhesive property is good, bonding as semi-synthetic hydrocarbon cracking catalyzer.Present aluminium colloidal sol mainly is that the employing metallic aluminium is the aluminium source, with the method production of dissolving with hydrochloric acid.Because metallic aluminium by the aluminium hydrate powder electrolytic preparation, needs to expend a large amount of electric energy in the production, the price comparison costliness of metallic aluminium causes the manufacturing cost of aluminium colloidal sol too high.And when adopting metallic aluminium to be the aluminium source,, causing prepared aluminium colloidal sol product easily muddy because reaction process is violent and unordered, adhesiveproperties is relatively poor.
November 28 calendar year 2001, disclosed Chinese patent application 00110421.7 provided a kind of preparation method of aluminium colloidal sol, it is characterized in that: under the condition of room temperature, be raw material with the inorganic aluminate, obtain precipitation by the method that adds excessive alkali, make the pH value greater than 9; Clean the back and add acid as the dispergation catalyzer, [H+]/[Al
3+] scope of mol ratio is 0.07-0.50, under action of ultrasonic waves, form stable, aluminium colloidal sol clearly, hyperacoustic physical parameter is: frequency 20-50KHz, sound intensity 50-150W.The inorganic aluminate that it adopts is aluminum nitrate, aluminum chloride or Tai-Ace S 150.Though the aluminium colloidal sol size ratio that should invent preparation is than homogeneous, stability is better, and whether the adhesiveproperties of not mentioning gained aluminium colloidal sol makes moderate progress, and employed in addition equipment and processing condition are higher, and production cost is still very high.
Summary of the invention
The purpose of this invention is to provide and a kind ofly adopt lower-cost multiple aluminum compound to be the aluminium source, can to improve the aluminium colloidal sol new process of production of aluminium colloidal sol adhesiveproperties again.
The technical solution used in the present invention is:
A kind of novel process for preparing aluminium colloidal sol, partly or entirely with aluminum oxide or/and aluminium hydroxide or/and boehmite replaces metallic aluminium is the aluminium source, add hydrochloric acid and prepare liquor alumini chloridi, prepare aluminium colloidal sol then, or directly directly prepare aluminium colloidal sol with liquor alumini chloridi instead of part metallic aluminium.
Concrete preparation method is: part with aluminum oxide or/and aluminium hydroxide or/and boehmite is aluminium source and hydrochloric acid is Al in molar ratio
2O
3: HCl=1: 3～12 mixed, stirring reaction is 2～18 hours in 80～150 ℃ of scopes, add entry or hydrochloric acid soln or contain the aqueous solution of aluminum chloride, press the proportion requirement of total aluminium content in the aluminium colloidal sol then and replenish the adding metallic aluminium, at 1～5 normal atmosphere, 80～150 ℃ scope internal reaction 3～40 hours, prepare the aluminium colloidal sol of desired concn.
The aqueous solution that adds entry or hydrochloric acid soln or contain aluminum chloride can prepare in the reaction process of aluminium colloidal sol adding metallic aluminium, also can be after the reaction of preparation liquor alumini chloridi, and before the reaction of preparation aluminium colloidal sol.Water or hydrochloric acid soln or the aqueous solution that contains aluminum chloride can divide once, once above or add continuously.
Another kind of preparation method is: all with aluminum oxide or/and aluminium hydroxide or/and boehmite is the aluminium source, by weight the ratio and the mixed in hydrochloric acid that are Al: Cl=1.0～1.4: 1, measure the content of aluminium and chlorine, at 1.5～5 normal atmosphere, 110～150 ℃ scope internal reaction 3～40 hours, prepare the aluminium colloidal sol of desired concn.
Also have a kind of preparation technology of aluminium colloidal sol to be: part is the aluminium source with the liquor alumini chloridi, press the proportion requirement of total aluminium content in the aluminium colloidal sol then and replenish the adding metallic aluminium, at 1～5 normal atmosphere, 80～150 ℃ scope internal reaction 3～40 hours, prepare the aluminium colloidal sol of desired concn.
Generally generate the required Al/Cl of aluminium colloidal sol than about 1.2,, can not satisfy the condition that generates aluminium colloidal sol, need adjust the Al/Cl ratio, satisfy the reaction conditions that generates aluminium colloidal sol by the additional metallic aluminium that adds because the Al/Cl in the aluminum chloride is smaller.Alumine ore deposit or bauxite chamotte and hydrochloric acid reaction after-filtration can make liquor alumini chloridi, and cost is lower.
First kind of optimal reaction temperature with the third method is 90～140 ℃, and reaction pressure is 1～3 normal atmosphere, and the reaction times behind the adding metallic aluminium is preferably 8～35 hours.
Preceding two kinds of technological processs all can adopt continuous processing and the operation of interruption method, when adopting continuous processing, the process that aluminum-containing raw material is prepared into aluminum chloride salt and further is prepared into aluminium colloidal sol is carried out continuously, in the interruption method, aluminum-containing raw material is prepared into the process of aluminum chloride salt and further preparation aluminium colloidal sol separately to carry out, and promptly separately carries out or proceed step by step in same reactor in different reactors.Stirring can adopt mechanical stirring, pump circulation to stir and the boiling alr mode.
After reaction product aluminium colloidal sol is filtered, can add that to account for aluminium colloidal sol gross weight be 0.1 ‰～9% auxiliary agent, to improve colloidal stability and to improve the performance of cracking catalyst.Said auxiliary agent is one or more the mixture in ammonium phosphate salt, phosphoric acid magnesium salts, phosphoric acid, zinc phosphate, sal epsom, zinc chloride, magnesium chloride, the zinc sulfate.Refilter after adding the auxiliary agent mixing, can obtain aluminium colloidal sol product stable, that transparency is higher.Also can filter the back and add auxiliary agent at aluminium colloidal sol.Ammonium phosphate salt comprises Secondary ammonium phosphate, primary ammonium phosphate and triammonium phosphate, and the phosphoric acid magnesium salts comprises trimagnesium phosphate and secondary magnesium phosphate.
When colloid is synthetic, if add the high price negatively charged ion, colloid will develop to unstable direction, for example SO
4 2-, PO
4 3-Plasma can reduce the stability and the transparency of aluminium colloidal sol.Can form the network structure of mixing high-valence cationic oxyhydroxide when in aluminium colloidal sol, introducing Mg, Zn, Si ion, help the stable of aluminium colloidal sol.
Beneficial effect of the present invention is: with aluminum oxide or/and aluminium hydroxide or/and boehmite is the aluminium source, all or part of replacement metallic aluminium, perhaps part is the aluminium source with the liquor alumini chloridi, has obviously reduced the production cost of aluminium colloidal sol; The adhesiveproperties of the aluminium colloidal sol of this prepared improves, the cracking catalyst of using the preparation of this aluminium colloidal sol and the cracking catalyst of using the aluminium colloidal sol that all prepares with metallic aluminium and hydrochloric acid reaction to prepare are under Preparation of catalysts technology, the identical condition of filling a prescription, tear strength can improve about 25%, and other performance is suitable.
