Abstract
The invention discloses a supported vanadium pentoxide catalyst used for removing dimethyl formamide through oxidation of supercritical water. A substance M is prepared after vanadium pentoxide is cleaned and modified with AgNO3; a substance N is prepared after mixed liquor prepared from polyvinylpyrrolidone, methyl alcohol, palladium dichloride, rhodium chloride trihydrate, concentrated hydrochloric acid and sodium borohydride is modified with the substance M; a substance O is prepared after mixed liquor prepared from CuCl2, CdCl2, concentrated nitric acid, urea and ammonium fluoride is modified with the substance N; a substance P is prepared after mixed liquor prepared from tetra-n-butyl ester titanate, tetraethyl orthosilicate and acetylacetone is modified with the substance O; a substance Q is prepared after mixed liquor prepared from SnCl4, SrCl2 and BiCl3 is modified by the substance P; a substance, namely, the supported vanadium pentoxide catalyst used for removing dimethyl formamide through oxidation of supercritical water is prepared after mixed liquor prepared from ZnCl2, SbCl3, NaOH, Na2CO3 and NiCl2 is modified with the substance Q.
Description
Technical field
The invention belongs to the supercritical Water Oxidation Technology field that organic wastewater with difficult degradation thereby is processed, it is used for surpassing particularly to one kind
The support type vanadium pentoxide catalyst of critical oxidation removal dimethylformamide.
Background technology
Supercritical water oxidation is a kind of wastewater processing technology that the eighties in 20th century grows up, mainly utilize molecular oxygen or
Hydrogen peroxide as oxidant, using supercritical water as solvent, oxidation Decomposition organic pollution.Due to supercritical in oxidizing process
The good dissolubility to various Organic substances and oxygen for the water, Organic substance, oxidant and supercritical water form homogeneous phase, and reaction is not
Meeting restriction hindered because of alternate mass transfer, reaction rate can greatly improve.Supercritical water oxidation treatment technology anti-
Answer generally 400~600 DEG C of temperature, pressure is 30~50MPa, the organic carbon in organic pollution changes into carbon dioxide, hydrogen
Change into water, halogen atom changes into the ion of halogenide, sulfur and phosphorus change into sulfate and phosphate, organic nitrogen transformation respectively
Become nitrogen, these products are nontoxic product.Therefore, supercritical Water Oxidation Technology has clearance height, reacts thorough, place
Effect is good for reason, non-secondary pollution the advantages of.
Although supercritical Water Oxidation Technology is an emerging pollutant treatment technology with broad prospect of application, it is high
The harsh reaction condition of warm high pressure is very high with the requirement of management level to running.Therefore, in order to accelerate reaction rate, reduce instead
Between seasonable, reduce reaction temperature, enable supercritical Water Oxidation Technology to give full play of the advantage of itself, many researcheres will be catalyzed
Agent introduces supercritical Water Oxidation Technology, develops catalytic supercritical water oxidation technology.Conventional in catalytic supercritical water oxidation technology
Catalyst be MnO2、CuO、TiO2、CeO2、Al2O3, the composite catalyst such as Cr of Pt or wherein several material composition2O3/
Al2O3、CuO/A12O3、MnO2/CeO2Deng, but these catalyst existence and stabilities can poor, the shortcomings of catalysis activity is relatively low,
Limit popularization and application in water process for the catalytic supercritical water oxidation technology and development, thus the research of new catalytic material with
Preparation also needs to strengthen further, particularly also lacks the catalysis removing dimethylformamide for supercritical water oxidation at present
Agent.
Content of the invention
It is an object of the invention to provide a kind of support type five removing dimethylformamide for supercritical water oxidation aoxidizes
Two vanadium catalysts, the comprising the following steps that of its preparation method:
(1) put into 500mL third after the 133g vanadium oxide particles 300mL deionized water wash being 4~6mm by particle diameter
Soak 1h in ketone, remove liquid after filtration and obtain material M0, material M0 obtains material M1 after 300mL deionized water wash, will
Material M1 puts in the hydrochloric acid solution that 300mL molar concentration is 2.5mol/L and soaks 0.5h, removes liquid and obtain thing after filtration
Matter M2,85 after material M2 300mL deionized water wash, then the washing with alcohol being 95% with 500mL mass percent concentration
DEG C drying baker in place 1.5h, obtain material M3, by material M3 be added to 250mL molar concentration be 2.67mol/L AgNO3
In solution, temperature be 65 DEG C shaking table in shake 75 minutes, be filtered to remove liquid after being cooled to room temperature and obtain material M4, material
