Description
Technical field
The present invention relates to a kind of reducing catalyst technology, especially relate to a kind of load type ozone nanometer type reduction catalyst and manufacture method thereof.
Background technology
Ozone is widely used in fields such as sterilization, deodorizing, wastewater treatment, and just directly enter atmosphere has certain threat to health to the ozone that has not consumed under not processed situation.Also can produce ozone in the modern electrical equipment, also will directly influence surrounding air by the ozone that corona discharge and electrion produce, have a strong impact on our healthy such as cabin, duplicator, printing machine, facsimile machine, sterilizing machine etc.Reducing catalyst preparation method kind in the market is more, each have their own performance characteristics.
As the patent No. is a ZL01105215.5 support type ozone (O
3) reducing catalyst and manufacture method thereof, it is characterized in that every 1KG column-shaped active carbon, add 140G～180G ferric nitrate, 120G～180G nickel nitrate, 0.002G～0.020G silver nitrate, 0.00001G～0.00020G palladium nitrate, 700ML～780ML deionized water, use deionized water dipping, in stainless container while rotating the oven dry macerate, temperature is controlled at 100 ℃～140 ℃, then 360 ℃～380 ℃ roasting temperatures 2～4 hours, naturally after the cooling, with 12 eye mesh screens screenings, loaded catalyst.
And for example the patent No. is that ZL01138151.5 has invented a kind of catalyst and preparation technology thereof who eliminates ozone and nitrogen oxide, and manganese nitrate, copper nitrate, nickel nitrate and silver nitrate are made nitrate solution; Placing nitrate solution to soak the back catalyst carrier takes out oven dry, places nitrogen to heat; Again catalyst carrier is placed nitrogen, hydrogen mixed gas heating back cool to room temperature.
Also be the preparation method and the equipment of a ZL200710118756.6 load type metal nanocatalyst just like the patent No., be under supersonic induced condition, with measuring pump with metal salt solution by the micropore on the hollow ceramic membrane tube wall be diffused into by reducing agent and carrier material form mixture slurry solution in, make metal ion absorbing and reducing on the catalyst carrier surface, centrifugation then, the precipitate with deionized water washing forms the load type metal nanocatalyst after oven dry and the calcination.
Summary of the invention
The objective of the invention is in order to solve the existing anti-steam poor-performing of reducing catalyst, the problem that service life is long, provide a kind of cost suitably, stable performance, durability be strong, can remove the Catalysts and its preparation method of ozone fast.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: this load type ozone nanometer type reduction catalyst and manufacture method thereof, it is characterized in that every kilogram of ultra-fine or nano active carbon, add 27g～725g manganese nitrate, 73g～590g copper nitrate, 0.019g～0.093g palladium nitrate, 650g～850g deionized water, flooded 0.5～1 hour, in freeze-day with constant temperature equipment, dry, then at the roasting temperature regular hour of setting, the loaded nano level catalyst of making after the cooling.
As preferably, described is carrier with ultra-fine or nano active carbon, is that the major catalyst palladium nitrate is secondary catalyst with manganese nitrate, copper nitrate, uses deionized water dipping, and each part is by certain proportioning.
As preferably, described in freeze-day with constant temperature equipment temperature be controlled at 100 ℃～120 ℃.
As preferably, described nitrate with manganese nitrate or copper or palladium is dissolved in the deionized water, immerse behind the activated carbon in freeze-day with constant temperature equipment 100 ℃～120 ℃ dry down, then 350 ℃～450 ℃ roasting temperatures of setting 2～4 hours.
Implementation result of the present invention is: anti-steam performance is good, reaches 1500-2500 hour service life, can reach ozone fully and send out exhaust emissions index 50ppb.
Therefore, the present invention be a kind of cost suitably, stable performance, durability be strong, can remove the Catalysts and its preparation method of ozone fast.
The specific embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
In the present embodiment, the carrier of catalyst adopts ultra-fine or nano level active carbon, and active component is a major catalyst by 2～20% manganese dioxide and 2～15% cupric oxide, and 0.01～0.02% palladium oxide is that secondary catalyst is formed.
The preparation method adopts dipping～roasting method preparation, the nitrate that is about to manganese nitrate and copper or palladium is dissolved in deionized water, immerse behind ultra-fine or the nano active carbon in 100 ℃～120 ℃ dry down, again 350 ℃～450 ℃ roasting temperatures 2～4 hours, the cooling back loaded nano level catalyst.
As get the 188g manganese nitrate, the 293g copper nitrate, 0.04g palladium nitrate, the 700ml deionized water, these several nitrate are dissolved in the deionized water, got in the deionized water that 1kg superfine active carbon dust is impregnated into mixed nitrate 1.5 hours, dry down in 100 ℃～120 ℃, 350 ℃～450 ℃ roasting temperatures 2.5 hours, promptly get Nano type load ozone reduction catalyst after the cooling again.
The characteristics of this catalyst are that anti-steam performance is good, long service life 1500-2500 hour, can reach ozone fully and send out exhaust emissions index 50ppb.
The foregoing description is to explanation of the present invention, is not limitation of the invention, any structure after the simple transformation of the present invention is all belonged to protection scope of the present invention.
