Background technique
Volatile organic matter compound (VOCs) refers to that saturated vapour pressure is greater than boiling point under 70Pa, normal pressure at normal temperature and exists
Organic compound within 260 DEG C, such as many benzene homologues, hydro carbons and alcohols are pollutants common in atmospheric environment.Existing
In foundry industry, the enterprises such as chemical industry, petrochemical industry, pharmacy, electronics, chemical fibre, rubber, coating and printing and dyeing, printing, coating, coating etc.
The generation and discharge of VOCs exhaust gas are directed in technical process, wherein benzene homologues have strong three-induced effect (mutagenesis,
Carcinogenic and teratogenesis), it is huge to ecological environment and human health damage, it need to be monitored and be handled.
Activated carbon fibre (activated carbon fiber) is combined using Carbon fibe technology and activated carbon technology
A kind of novel carbon material adsorbing material to grow up, with traditional granular activated carbon (granular activated carbon)
It compares, activated carbon fibre (ACF) has that large specific surface area, micropore are flourishing, pore-size distribution is narrow, adsorption rate is fast, adsorption capacity is strong
The features such as being easy with regeneration.In order to improve activated carbon fibre to greatest extent to the adsorption capacity of atmosphere pollution, both at home and abroad all
In the modification work for carrying out a series of activated carbon fibre.
Document 1 (Zhang etc., Journal of the American Chemical Society, 2010, the 132nd
Volume, page 6294~6295) report hexafluorophosphoric acid type ionic liquid (Bmim-PF with -3 methyl-imidazoles of 1- butyl6) conduct
Phosphorous additive is mixed with dicyanamide carries out thermal polymerization, to obtain a series of nitrogen carbide (g-C of P Modifications3N4) material,
The content highest of P elements can achieve 3.5%.Document 2 (Wang Yongfang etc., Acta PhySico-Chimica Sinica, 2016, the 2nd phase of volume 32,
Page 481~492) a kind of different types of phosphorous active carbon with the modified preparation of phosphoric acid activation is reported, P elements are maximum
Content is only 5.8%.The content for further increasing P elements is the key that optimization P Modification activated carbon adsorption performance, and phosphorus doping
The modified activated carbon fibre of nitrogen carbide is used to adsorb the research of volatile organic matter, is still rarely reported.
Summary of the invention
In view of the foregoing deficiencies of prior art, the purpose of the present invention is to provide a kind of realization economical and energy savings, green
