Abstract
The present invention relates to a method for preparing ceramic whitening agent by using deactivated low-temp. transformation catalyst and its product. Said method is as follows: the low-temp. transformation catalyst waste residue is passed through such processes of hand-selecting, removing impurity, pulverizing and screening, and then fed into a high-temp. furnace to make calcination for 2-5 h., and its calcination temp. is controlled within 400-1400 deg.C, and then the above-mentioned material is discharged from furnace, and cooled to normal temp. Besides, in the material passed through the processes of hand-selecting and removing impurity, a rare earth synergistic solution is injected, and then the above-mentioned material is fed into the high-temp. furnace to make calcination said invention can change the industrial waste residue into in dustrial raw material, and its obtained product can resist high-temp. of above 1300 deg.C, and its whitening effect is notale.
Description
The present invention relates to a kind of manufacture method of ceramic whitening agent, especially a kind ofly utilize low temperature (containing wide temperature) the transformation catalyst waste residue behind the inactivation to make method of ceramic whitening agent and products thereof.
In recent years, some chemical plant, as being the synthesis ammonia plant etc. of raw material with the coal, for energy-conservation numerous and confused employing low temperature (containing wide temperature) transformation catalyst, this catalyzer just becomes industrial residue through producing after using inactivation, needs a large amount of manpower and materials of cost remove to handle these waste residues.
Once there was the ceramic whitening agent of trial sale to occur on the market, but all can not be high temperature resistant, so do not have whitening effect.
The object of the present invention is to provide that a kind of to utilize low temperature (containing wide temperature) the transformation catalyst waste residue behind the inactivation be raw material, manufacturing can be high temperature resistant, has the method and products thereof of the ceramic whitening agent of tangible whitening effect.
Technical solution of the present invention is:
A. the low temperature shift catalyst waste residue behind the inactivation is carried out picking, removes dirty foreign material wherein, pulverize with pulverizer again, cross 60～120 mesh sieves,
B. the material after above-mentioned the sieving is sent in the high-temperature calcination stove and calcined 2～5 hours under the condition that has air to exist, calcining temperature is controlled at 400～1400 ℃,
C. the material after the above-mentioned calcining is come out of the stove and reduce to normal temperature, promptly obtain finished product.
In the present invention, being preferably in the material behind the crushing screening is 0.1～0.2 with the ratio with material equably: ratio spray concentration 1(weight) is 10～15%(weight) rare earths salt, send into again in the high-temperature calcination stove and calcine.
In the present invention, calcining temperature is controlled at 650～1200 ℃ more satisfactory.
In the present invention, also the low temperature shift catalyst waste residue behind the inactivation can be carried out not pulverizing earlier after the picking removal of impurities, add rare earths salt or do not spray rare earths salt, send in the High Temperature Furnaces Heating Apparatus and calcine, reduce to normal temperature after calcining is come out of the stove, use the pulverizer crushing screening again, obtain finished product.
The low temperature shift catalyst of Shi Yonging mainly is meant various Co-Mo sulfur-tolerant shift catalysts in the present invention, as LHB301 low temperature sulfur-resistant transformation catalyst; B301, B302Q, each molded breadth temperature sulfur-resistant transformation catalyst of B303Q; And the K8-11 type co-mo antisulphuric transforming catalyst produced of BASF AG etc. all can.Its main chemical compositions is the oxide compound of cobalt, molybdenum and aluminium, uses the main chemical compositions of the catalyst waste slag behind the inactivation to be the sulfide of cobalt, molybdenum and oxide compound and a small amount of dirty foreign material of aluminium.
Used in the present invention high-temperature calcination stove can be electric furnace, rotary kiln etc., also can utilize the native stove, the native kitchen range that burn coal to calcine.
Processing method of the present invention also is applicable to utilizes the industrial low-temperature transformation catalyst to make ceramic whitening agent for raw material, but cost is higher.
The present invention becomes industrial residue into industrial raw material, turns waste into wealth; Can be high temperature resistant more than 1300 ℃ by the ceramic whitening agent that the present invention obtains, this whitening agent added in the enamel raw material by a certain percentage make glaze, can be directly into fired ceramic in the high temperature kiln; Ceramic whitening agent whitening effect of the present invention is obvious, and general fluorescent, gives aesthetic feeling, to those enamel material of yellowing slightly, add this agent after whitening effect better.This whitening agent is through Jing Dezhen ceramics factory, and high An County red plum architectural pottery head factory is on probation, and whitening effect is obvious.
Below in conjunction with embodiment the present invention is described in more detail.
