9%, nickel oxide 4~6%, silver 1~4%, palladium 0.2~0.3%.On honeycomb metal fin carrier (hereinafter referred to as carrier)
The process for coating above-mentioned catalyst is as follows:
1, on carrier Glass-Coated process:
1) nitrate for adding distilled water to be configured to certain mass concentration in the nitrate of substance each in glass coating first is molten
Liquid:
Sodium nitrate (NaNO3): 6~40%
Potassium nitrate (KNO3): 8~22%
Lithium nitrate (LiNO3): 8~15%
Nine water aluminum nitrate (Al2(NO3)39H2O): 10~35%
Four water-calcium nitrate (Ca (NO3)24H2O): 10~25%
Strontium nitrate (Sr (NO3)2): 10~25%

The distilled water solution for the boric acid that mass concentration is 10~15% is prepared again, then by the mixed of above-mentioned 4~8 kinds of nitrate
Solution and boric acid solution mixing are closed, is stirred 0.5~1 hour at a temperature of 50 DEG C~60 DEG C, until solid salt all dissolves；
2) teos solution of 15~25 milliliters of weighing, the ethyl alcohol for being then 85% by 6~7 milliliters of mass concentrations, 3
The nitric acid that~4 milliliters of distilled water and 0.5~2 milliliter of mass concentration are 65% is uniformly mixed stirring；Then with 1~2.5ml/
The mixed solution prepared is poured into teos solution and stirs by the speed of min, ultimately forms transparent solution；
3) mixed solution of 10~50ml boric acid and nitrate that step 1) obtains is fallen with the speed of 1~2.5ml/min
Enter in the ethyl orthosilicate mixed solution of step 2), constantly stirs 0.5~3 hour, finally formed mixed solution is glass
Glass coating solution；
After preparing glass coating solution, honeycomb metal wing carrier is immersed, 5~10 minutes every time, is applied repeatedly
It covers 3~5 times, is dried up between twice of every coating with hair dryer, finally inhaled at room temperature using absorbent cotton, filter paper etc. in air
Enclosure material makes it dry in the shade 2~12 hours, then 2~4 dry at a temperature of 60 DEG C~180 DEG C in air in drying box
Hour, furnace cooling takes out, obtains to surface and be coated with the metal tube carrier of glass coating.
2, catalyst is coated on honeycomb metal wing carrier vector:
