Abstract
The invention discloses a load-type foamed aluminum catalyst for removing dimethyl formamide by use of supercritical water oxidization. The load-type foamed aluminum catalyst for removing dimethyl formamide by use of supercritical water oxidization is prepared by virtue of the following steps: washing foamed aluminum, and then modifying the washed foamed aluminum with AgNO3, thereby obtaining a substance M; modifying a mixed solution prepared from polyvinyl pyrrolidone, methanol, gold trichloride, concentrated hydrochloric acid and sodium borohydride by the substance M, thereby obtaining a substance N; modifying a mixed solution prepared from SrCl2, CoCl2, concentrated aqua fortis, urea and ammonium fluoride by the substance N, thereby obtaining a substance O; modifying a mixed solution prepared from tetra-n-butyl titanate, tetraethyl orthosilicate and acetylacetone by the substance O, thereby obtaining a substance P; modifying a mixed solution prepared from ZrCl4, MgCl2 and InCl3 by the substance P, thereby obtaining a substance Q; and modifying a mixed solution prepared from PbCl2, BiCl3, NaOH, Na2CO3 and CdCl2 by the substance Q, thereby obtaining a substance, namely the load-type foamed aluminum catalyst for removing the dimethyl formamide by use of supercritical water oxidization.
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 foam Al catalysts 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 foamed aluminium removing dimethylformamide for supercritical water oxidation
Catalyst, the comprising the following steps that of its preparation method:
