Low temperature water resistant, dust tightness catalyst technical field in preparation.
Background technique
As the atmosphere pollutants emission standards of country's revision are increasingly strict, industrial enterprise has carried out a large amount of atmosphere pollution
Object control measure, wherein SCR technology (SCR) is widely used.Currently, vanadium base or rare earth based denitration catalyst
Low temperature active in a large amount of has been carried out to be modified, low-temperature SCR catalyst is significantly improved in 160-300 DEG C of denitration efficiency in part,
85% or more, meet the demand for control of the industrial smokes atmosphere pollution such as coking, glass.But many denitrification apparatus pass through 1 year
Operation after, catalytic efficiency is substantially reduced or even situations such as burn into blocking occurs in partial denitrification device downstream line.Coking,
In the industrial smokes such as glass, often contain a large amount of SO2, under the action of vanadia-based SCR catalysts, SO2Catalysis oxidation is SO3With
NH3In conjunction with, under the action of water generate ABS(ammonium hydrogen sulfate, NH4HSO4), then combine and adhere to dirt, the ash content etc. in flue gas
In flue.ABS fusing point is at 147 DEG C, and boiling point is in 350 DEG C, middle low-temperature denitration, desulfurization and dust-extraction unit, flue-gas temperature
Often below 300 DEG C, the ABS bur of formation is difficult to decompose, and flue is caused situations such as burn into blocking occur.Therefore, it solves
Certainly the main method of this persistent ailment is the anti-ABS of low-temperature SCR catalyst and water resistant anti-dust performance in improving.
CN 109647376A discloses the preparation method and product of a kind of hydrophobic performance sulfur resistive low-temperature denitration catalyst, makes
Ti-SiO is prepared with butyl titanate, ethyl orthosilicate, acetylacetone,2,4-pentanedione, dehydrated alcohol, P123, ammonium lauryl sulfate etc.2
Then carrier is added the precursor preparations such as vanadium, molybdenum, tungsten and goes out honeycomb type denitrification catalyst, NO conversion ratio is in 70- at 180 DEG C
80%, catalytic activity is weaker and specific hydrophobic performance does not refer to.CN 109529948A discloses a kind of raising manganese-based low-temperature
SCR denitration water resistant, the method for resistance to SO_2, by nanoscale N06 polytetrafluoroethylene (PTFE) and MnO2Doping, after 200 DEG C of calcinings
To water resistance manganese based denitration catalyst, optimal catalyst is at 160 DEG C, NOxConversion ratio is in 63% or so, at 180 DEG C, NOxTurn
Rate is 85%, but the disadvantages of polytetrafluoroethylene (PTFE) additional amount is higher (20%), and active temperature section is relatively narrow.In conclusion domestic
Outer patent is mainly by being added there is the organic matter of water resistance to realize about sulfur resistive low-temperature denitration catalyst preparation method
, but a large amount of organic metal salt has been used, and processing step is complicated, is difficult industrial applications, and operating temperature section
Relatively narrow, at 180 DEG C, NO conversion ratio is 80% or so, it is difficult to meet industrial application demand.
