Abstract
The present invention relates to an active carbon fiber for eliminating foul gas, and a preparation method thereof, and the preparation method comprises the following steps of drying an active carbon fiber at the temperature of 100 to 150 DEG C, soaking the active carbon fiber in copper salts with use concentration of 0.5 to 10% for 0.5 to 24 hours, and treating the active carbon fiber for 2 to 10 hours at the temperature of 100 to 450 DEG C in air or in inert gas to obtain deodorizing materials. The present invention has the advantages of no pollution, low cost, favorable deodorizing effect, and greatly improves the cost/performance ratio under the condition of properly increasing the cost.
Description
Technical field:
The invention belongs to a kind of material that removes foul gas, relate in particular to a kind of NACF that removes foul gas and preparation method thereof.
Background technology:
In recent years, an importance as environmental pollution improvement, the improvement of the odor pollution of commercial production and living facilities also has been subjected to unprecedented attention, processing material at odor pollution constantly is developed, people have at first developed the sensation deodorizing method, promptly shelter foul smell with discharging the aromatic series material, this method is simple and convenient, but is not that the basic method foul smell that effects a radical cure also exists in air, and scientific and technical personnel develop chemical deodorizing method again, promptly be to pass through oxidizing process, firing method, chemical reactions such as chemical reagent absorption process are handled foul smell, and this method has high selectivity, but there is secondary pollution, the shortcoming that service life is short.
In order to overcome above-mentioned shortcoming, people develop microbial decomposition foul gas molecule and catalyzed conversion foul smell molecule process again, but there is the higher shortcoming of cost, so scientific and technical personnel develop the absorbing and deodorizing method, promptly utilize active carbon or silica gel that the foul gas molecule is carried out physics or chemisorbed, but exist dynamic adsorption capacity relatively poor, the shortcoming that adsorption capacity is less.
Summary of the invention:
Goal of the invention of the present invention provides a kind of pollution-free, and cost is low, and absorbability is big removes NACF of foul gas and preparation method thereof.
The object of the present invention is achieved like this, handle NACF with certain density copper salt solution, Low Temperature Heat Treatment certain hour under certain atmosphere then, make the deodorize material, because the activated carbon fiber-loaded active ingredient copper that goes up, make it that deodorizing performance is big have been improved, so just improved the ratio of performance to price, be applicable to suitability for industrialized production.
Composition of the present invention is (percentage by weight)
NACF 92-98% Cu 2-8%
Its physical property is specific surface area (m
2/ g) 200-1000
The physical property of the aforesaid NACF of pore volume (cc/g) 0.1-0.4 is:
Specific surface area (m
2/ g) 500-1200
Pore volume (cc/g) 0.2-0.6
Aforesaid NACF is a polyacrylonitrile radical active carbon fiber, viscose glue base activated fibre, asphalt based active carbon fiber, phenolic resin based activated carbon fiber.
Aforesaid Cu is the simple substance of copper, Cu oxide, copper sulfide.
Preparation method of the present invention be with NACF the 100-150 ℃ of down dry back working concentration mantoquita impregnation process that is 0.5-10% 0.5-24 hour, then in air or inert atmosphere, handle the deodorize material that made in 2-10 hour under 100-450 ℃ of temperature.
The deoxidation material that the present invention makes is applicable to the processing of sulfur series foul smell gas by using gas.
The present invention compared with prior art has following advantage:
(1) pollution-free.
(2) cost is low.
(3) deodorising effect is good.
(4) under situation about suitably raising the cost, improved the ratio of performance to price greatly.
