Description
Technical field
The invention belongs to the technical fields of air purification, provide a kind of catalyst of catalysis burning eliminating organic pollutant
And preparation method.
Background technology
Haze is the particles such as PM2 .5 equidimensions particle, dust, the aerosol floated in air, in certain humidity, temperature
The weather phenomenon generated under the weather conditions metastable states such as degree is the knot of specific weather condition and mankind's activity interaction
Fruit.Haze disaster, caused by being Atmospheric Long-term pollution as a result, mainly by extensive economy development pattern, the industrial structure and energy
Caused by source structure is unreasonable, the extensive application of fossil fuel is had its source in.Specifically, vehicle exhaust, coal-burning stove for heating, work
Industry discharge, printing and dyeing discharge, building and dust on the roads be pollutant in haze main source, once pollutant be chronically at it is unfavorable
Haze weather is easily formed under the meteorological condition of diffusion.
In air pollutants, the pollution of volatile organic contaminant not only causes the generation of Organic aerosol, generates mist
Haze, and there is direct human toxicity and environmental toxicity, therefore, control pollution sources are discharged into the root that air is air conservation
This.But due to the limitation of emission operating mode, it is difficult to effective limiting emission at present, discharge can only will be reached after emissions processes and is wanted
It asks, the pollution to air is reduced with this.Absorption process, combustion method, bioanalysis etc. are mainly used to the processing of emission.But it is limited to
The type of volatile organic contaminant is various, complicated component, distinct, uses single purification techniques often in many cases
It is difficult to reach improvement requirement.Such as combustion method, the burning of light-concentration volatile organic pollution is not obvious.
Catalysis burning is a gas-solid-phase catalytic reaction process, and the essence of reaction is the deep oxidation that active oxygen participates in
Effect.In catalyticing combustion process, catalyst has suction-operated, while can reduce the activation energy of reaction, by that will react
Object molecule is enriched in catalyst surface to improve reaction rate, accelerates reaction process.Using the excellent properties of catalyst, can make
Flameless combustion occurs under lower initiation temperature (200 ~ 300 DEG C) for organic exhaust gas, and oxygenolysis is carbon dioxide and water, together
When release a large amount of thermal energy, to processing volatile organic matter it is significant.
At present both at home and abroad in terms of the catalyst of catalysis burning, the especially catalyst of catalysis burning volatile organic compounds
Certain effect is achieved.Wherein Zeng Wanyun et al. has invented a kind of prepare and has been catalyzed the spherical shell type catalyst to burn for VOCs
Method（Chinese invention patent application number 201310334761.6）, include the following steps：Cerium-containing compound and urea are dissolved in
In ionized water, it is sufficiently stirred hot kettle of falling back and carries out microwave hydrothermal；By gained washing of precipitate, drying, calcining after cooling；By ball
Shell mould CeO2Powder be dissolved in the mixed solution of compound containing platinum and copper-containing compound stir after, filtering, gained washing of precipitate,
Drying is calcined again to get powdered spherical shell type catalyst Pt/CuO-CeO2, the catalyst dispersity of the invention is good, there is spherical shell
The special appearance of type possesses larger specific surface area, is conducive to absorption of the pollutant in catalyst surface, and can provide more
Noble metal combination rare earth element is effectively overcomed easily poisoning and the shortcomings of non-refractory by active site.To benzene homologues such as first
The catalyst combustion reaction of benzene has very high catalytic activity, and prepares raw material and be easy to get, simple process.In addition, Zhao Weirong hairs are illustrated one
Catalyst and preparation method of the kind for VOCs catalysis burnings（Chinese invention patent application number 201610490126.0）, the catalysis
Agent be using ceramic honey comb matrix as skeleton, using account for the aluminium oxide of ceramic honey comb substrate quality 10% ~ 15% as coating, to account for honeycomb
The Pt of ceramic matrix quality 0.05% ~ 0.2% and 1% ~ 5% Cu are as active component.Preparation process of the present invention is simple, compares table
Area is big, at low cost, is suitble to large-scale production, after the invention is to the processing of ceramic honey comb matrix, active component and basal body binding force
By force, not easily to fall off and cracking remains to keep greater activity, gained catalyst right at 260 DEG C under high-speed air-flow and thermal shock
Toluene conversion reaches 98%, and T98 reduces 20 DEG C compared with same catalyst；240 DEG C reach the catalytic efficiency of ethyl acetate
To 98% or more, T98 reduces 30 DEG C compared with same catalyst.
