Abstract
A kind of mixed light rare earth catalyst for exhaust purification can be used for purifying industrial organic waste gas and vehicle exhaust.It is an active component with the oxide of copper, manganese, mixed light rare earth and barium, and the weight ratio between them was respectively 5: 4: 7: 1, and with commercially available γ-Al
2O
3Bead is a carrier, and the weight ratio of carrier and active component is 100: 10～20.Catalyst forms through dipping, calcination with the nitrate of above-mentioned various metals.This catalyst has makes simple, aboundresources, advantage such as cheap, and the organic exhaust gas and the vehicle exhaust that are used for purifying silicon steel sheet production all have good active and service life.
Description
A kind of mixed light rare earth catalyst for exhaust purification can be used for purifying automobile tail gas and industrial organic exhaust gas.
General mixed light rare earth catalyst for exhaust purification is all with γ-Al
2O
3Being carrier, is main active component with the oxide of manganese and mixed light rare earth.For carbon monoxide in purifying industrial organic waste gas and the vehicle exhaust and hydrocarbon, it is active component that the present invention has adopted the oxide with copper, manganese, mixed light rare earth and barium, and the weight ratio between them was followed successively by 5: 4: 7: 1; γ-Al with commercially available φ 4～6mm
2O
3Bead is a carrier, and the weight ratio of it and active component is 100: 10-20.Active constituent wherein all can be formed by commercially available nitrate thermal decomposition.This catalyst can utilize common infusion process drying, calcination to form.
Purifying the turpentine wet goods organic solvent waste gas that produces in the silicon steel sheet manufacture process with this catalyst, is 20000hr at 380～420 ℃, air speed
-1The time, the initial purge rate is 87-92%, uses after 1 year 05 months, purifying rate still is 80～85%, also can save six over thousands of yuan of energy costs simultaneously every year.
Can economy, acceleration and the noise etc. of automobile not influenced to some extent during with this catalyst purifying automobile tail gas yet.For example three liters of catalyst are contained on the 130 type automobiles of Beijing, after more than 27,000 kilometers uses, purifying rate still can reach when idling is travelled: CO is 90%, and HC is 83%.
Embodiment: copper nitrate 510 grams, manganese nitrate 600 grams, mixed light rare earth nitrate 600 grams and barium nitrate 60 grams are dissolved in 2 premium on currency, immerse γ-Al
2O
33 kilograms in carrier, placement is spent the night, and boils off moisture content again in water-bath, in 120 ℃ down dry, 500 ℃ of following calcinations 2 hours, again 550 ℃ of following calcination half an hour.

Claims (2)
1, mixed light rare earth catalyst for exhaust purification is generally with γ-Al
2O
2Being carrier, is main active component with the oxide of manganese and mixed light rare earth, the invention is characterized in, carrier is γ-Al of commercially available Φ 4～6mm
2O
3Bead, active component are the oxide of copper, manganese, mixed light rare earth and barium.The weight ratio of its carrier and active component is 100: 10～20; Weight ratio between the active component was followed successively by 5: 4: 7: 1.
2, according to claim 1,2 catalyst, said active component is characterized in that they are formed by commercially available nitrate thermal decomposition.
