Abstract
The invention discloses a faveolate denitration catalyst which is prepared from the following components in parts by weight: 70-90 parts of titanium dioxide, 8-16 parts of tungsten trioxide, 1.5-3 parts of vanadium pentoxide, 2-6 parts of pulp cotton and 1.5-3 parts of stearic acid. The denitration catalyst has the advantages of easy moulding and demoulding in the manufacturing process, ideal porosity, high catalyzing efficiency, low use level and low cost.
Description
Technical field
The present invention relates to catalyst technical field, be specifically related to a kind of Faveolate denitration catalyst.
Background technology
Nitrogen oxide (NO
X) be a kind of atmosphere pollution with very big harm, all can cause certain injury to health and animals and plants existence, as forming acid rain, photochemical fog etc.; Environmental consciousness with require more and more stronger today, the discharging of how to remove nitrogen oxide becomes more and more urgent problem; At present, the nitrogen oxide of China mainly produces from the discharging of coal combustion and industrial smog, removes nitrogen oxide to a certain extent though tradition is used to remove the catalyst of nitrogen oxide; But; Still exist manufacturing process to be not easy shaping and demoulding, and the porosity of finished catalyst is undesirable, catalytic efficiency is low, catalyst amount is big, the high deficiency of cost.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of manufacturing process easy shaping and demoulding, and ideal porosity, the Faveolate denitration catalyst that catalytic efficiency is high, catalyst amount is few, cost is low.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of Faveolate denitration catalyst, and this catalyst is prepared from each component of following parts by weight:
Titanium dioxide TiO
2(titanium white powder) 70～90 parts
Tungstic acid WO
38～16 parts
Vanadic anhydride V
2O
51.5～3 parts
Cotton 2～6 parts of paper pulp
1.5～3 parts of stearic acid.
Titanium dioxide of the present invention, parts by weight are preferably 75～85 parts.
Tungstic acid of the present invention, parts by weight are preferably 8～14 parts.
Above-mentioned titanium dioxide is nano titanium oxide, and particle size range is 10～50nm.
It is cotton available from U.S. Marion Jessup LD-E paper pulp that above-mentioned paper pulp cotton is preferably employing.
Advantage of the present invention and beneficial effect:
1. the cotton adding of paper pulp in the denitrating catalyst of the present invention; The porosity (porosity be originally 0.2 added to reach 0.35 after the paper pulp cotton) and the specific area of catalyst have been increased; Thereby improved the catalytic efficiency of catalyst, reduced catalyst consumption and use cost;
2. stearic adding in the denitrating catalyst of the present invention helps the shaping and demoulding of catalyst, has improved the yield rate that catalyst is made.
3. denitrating catalyst of the present invention is at titanium dioxide; Tungstic acid; In the matrix of vanadic anhydride conduct; Add paper pulp cotton and stearic acid, thus brought into play above-mentioned paper pulp cotton with the two synergy of stearic acid, the feasible catalyst of preparing has high porosity and good shaping and demoulding effect simultaneously.
The specific embodiment
The invention is further illustrated by the following examples, but the present invention not only is confined to following examples.
The paper pulp cotton that embodiment uses is cotton available from U.S. Marion Jessup LD-E paper pulp, and the titanium dioxide that embodiment uses is nano titanium oxide (particle diameter 10～50nm).Tungstic acid, vanadic anhydride and stearic acid all adopt the commercially available prod.
Embodiment 1
Take by weighing each component of following parts by weight according to following ratio:
70 parts of titanium dioxide

1.8 parts of vanadic anhydrides
2.5 parts of paper pulp cotton (cotton) available from U.S. Marion Jessup LD-E paper pulp
1.6 parts of stearic acid.
Above-mentioned raw materials is prepared finished product through following making step; Adopt the preparation of industry current techique, roughly process is following: mixing after raw material is weighed---extrudes in advance and---oldly---extrudes that---primary drying---assemble by redrying---calcining---module.
Embodiment 2
85 parts of titanium dioxide
12 parts of tungstic acids
2.4 parts of vanadic anhydrides
Cotton 4 parts of paper pulp
2 parts of stearic acid.
Preparation process is with embodiment 1.
Embodiment 3
90 parts of titanium dioxide
15 parts of tungstic acids
3 parts of vanadic anhydrides
Cotton 5.5 parts of paper pulp
3 parts of stearic acid.
Preparation process is with embodiment 1.
Embodiment 4
80 parts of titanium dioxide
10 parts of tungstic acids
2 parts of vanadic anhydrides
4 parts of paper pulp cotton (cotton) available from U.S. Marion Jessup LD-E paper pulp.
2 parts of stearic acid.
Making step is with embodiment 1.
With the catalyst sample of above-mentioned preparation, carry out Performance Detection: testing result shows that denitrating catalyst porosity of the present invention increases, thereby has improved catalytic efficiency; Reduced catalyst amount; Reduced use cost, and the easy demoulding of preparation process, the finished product rate also is improved.
Catalyst sample as with embodiment 4 preparation is an example, uses specific area and lacunarity analysis appearance test sample porosity: porosity is 0.2 when cotton by former no paper pulp, after having added the paper pulp cotton, can reach 0.35.
