Abstract
The invention discloses a method for preparing a lanthanum-cerium-zirconium complex through atomization combustion, which comprises the following steps of: adding lanthanum nitrate, strontium nitrate and zirconium nitrate into ethanol water; after dissolution, controlling the temperature to 35-45 DEG C; and then atomizing and combusting in a combustion chamber at 450-600 DEG C to obtain a lanthanum-cerium-zirconium complex. Furthermore, the mass concentration of the ethanol water is 40-75%, and the weight parts of the lanthanum nitrate, strontium nitrate and zirconium nitrate are 5-15 parts, 20-80 parts and 15-60 parts respectively. Compared with the prior art, the method disclosed by the invention has the advantages of simple technology, easiness in operation, good complex activity and strong high temperature resistance and poison tolerance.
Description
Technical field
The present invention relates to one and prepare lanthanum cerium zirconium composite method.
Background technology
Lanthanum cerium zirconium composite as catalyst, for the process of vehicle exhaust.Through retrieval, do not find the prior art identical with the present invention.
Summary of the invention
For the problems of the prior art, the invention provides one and prepare lanthanum cerium zirconium composite method.
In order to achieve the above object, technical scheme of the present invention is: a kind of spray burning prepares lanthanum cerium zirconium composite method, lanthanum nitrate, strontium nitrate, zirconium nitrate are added in ethanol water, after dissolving, control temperature is at 35 ~ 45 DEG C, then be atomized in combustion chamber combustion, chamber temperature is 450 ~ 600 DEG C, obtains lanthanum cerium zirconium composite.
Further, described ethanol water mass concentration is 40 ~ 75%.
Further, the parts by weight of lanthanum nitrate, strontium nitrate, zirconium nitrate are respectively 5 ~ 15, and 20 ~ 80,15 ~ 60.
Further, in ethanol water, the molar concentration of lanthanum ion, strontium ion, zirconium ion sum is 0.8 ~ 2mol/L.
Compared with prior art, present invention process is simple, and be easy to operation, complex activity is good, and high temperature resistant anti-poisoning capability is strong.
