Description
The invention belongs to catalyst and application process thereof, relate in particular to a kind of desulfurization catalyst of flue gas and application process thereof.
Environmental pollution is one of human subject matter that faces now.Wherein the discharging of SOx and NOx is particularly outstanding to the harm of environment in the coal-fired flue-gas, and they are the principal elements that constitute acid rain, are subjected to the generally attention of countries in the world.Therefore, it is imperative to cut down its discharge capacity significantly, and China is a producing coal and uses coal big country, and sulphur coal is distributed more widely, SO
2Discharge capacity nineteen ninety-five leap to the first in the world, acid rain has appearred in national most of provinces and cities in succession, wherein the pH value of serious regional acid rain is low to moderate 3.24, state is to SO still
2Emission control anxious to be solved.
Coal-fired flue gas desulfurization technology (FGD) is broadly divided into two classes: wet desulphurization and dry desulfurization.Wet desulphurization exists complex process, equipment huge, take up an area of big, capital expenditure and operating cost height, water consumption is big, easily causes shortcomings such as secondary pollution.And dry desulfurization carries out under the bone dry state that no liquid phase gets involved, and product also is the dry powder shape, does not have problems such as burn into dewfall, small investment, operating cost is low, and is simple to operate, can not bring new harm, so the research of dry desulfurization is in rising trend in recent years to environment.
Dry desulfurization is mostly by the SO in desulfurizing agent absorption or the absorption flue gas
2, the desulfurizing agent after saturated is regenerated the high concentration SO that discharges during regeneration
2, can further be processed into sulfuric acid, sulphur and liquid SO
2The most economical configuration of coal burning flue gas desulfurization system should be after deduster, and corresponding flue-gas temperature is 120-250 ℃, and not only the process power consumption is low in this configuration, and can reduce dust poisoning desulfurizing agent greatly.At present, the more dry-desulphurizer of research has CuO/Al
2O
3, CuO/SiO
2And activated coke (charcoal) etc.As Journal of chemical engimeerin g of Japan, Vol 16, and No.21983:127-131 has reported CaO/Al
2O
3Catalyst, but because of CuO/Al
2O
3And CuO/SiO
2The desulphurizing activated temperature of desulfurizing agent higher (＞300 ℃); As Carbon, Vol, 31, No.1,1993:47-51 have reported activated coke (charcoal), though activated coke (charcoal) near normal temperature to SO
2Bigger absorption Sulfur capacity is just arranged, but subtract along with the raising Sulfur capacity of temperature is poly-, its Sulfur capacity is quite low in the time of 200 ℃, so above desulfurizing agent is desulphurizing activated all lower at the optimum flue gas desulfurization temperature window of Industrial Boiler (120-250 ℃).
Goal of the invention of the present invention provide under a kind of suitable Industrial Boiler flue gas desulfurization temperature (120-250 ℃) use, desulphurizing activated high catalyst and application process thereof.
Catalyst of the present invention is to be basic catalyst component with copper, and the raw material of wood-charcoal material is a catalyst carrier, and its catalyst each component percentage by weight is:
Raw material of wood-charcoal material 76.2-93.8% cupric oxide 6.2-23.8%
Above-mentioned raw material of wood-charcoal material carrier comprises active carbon, activated coke or NACF.
The concrete preparation method of catalyst is as follows:
The raw material of wood-charcoal material is put into Cu (NO
3)
23H
2In the O solution, flooded 0.5-20 hour, or after adopting incipient impregnation, placed 0.5-5 hour, the back is 60 ℃ of dryings 5 hours, calcines 2 hours in 200-450 ℃ after 6 hours 110 ℃ of dryings then, promptly gets catalyst.
The method that catalyst is used for 120-300 ℃ of flue gas desulfurization is as follows:
Catalyst is packed in fixed bed or the moving-burden bed reactor, and reaction temperature is controlled at 120-300 ℃, feeds the normal pressure flue gas, and air speed is 500-80000h
-1, Ar is a balance gas, desulfurization degree is higher than 80%, saturated Sulfur capacity 2.9-6.2gs/100g.
The present invention compared with prior art has following advantage:
1. desulfurization degree height, desulfurization degree is greater than 80%.
2. after this catalyst-assembly can be installed on deduster, so operating cost is low.
3. catalyst is a catalyst carrier with the raw material of wood-charcoal material of cheapness, so cost is low.
