Abstract
The invention relates to a gas adsorbing material, in particular to an acid gas adsorbing material. The acid gas adsorbing material comprises a flaky substrate of a porous structure, an active carbon fiber is adopted as the substrate, the substrate is dipped in an adsorbent composition which comprises polyamine and a coexisting polymer chemically bonded with polyamine, and the coexisting polymer is chemically boned with polyamine and the active carbon fiber simultaneously. The adsorbing material has the high durability and the good adsorbing capacity to acid gas.
Description
Technical field
The present invention relates to for capturing from air-flow or the adsorbent composition of separate targets gas, specificallyA kind of sour gas sorbing material.
Background technology
Industrial technology produces sour gas conventionally as refuse or accessory substance. Many these type of sour gas arePollutant or there is serious ambient influnence. For example, carbon dioxide (CO2) is considered to global warmingA main source because believe that it has strong contribution for greenhouse effects. Other gases,For example H2S, NOx and SOx may be poisonous or may cause environmental problem, for example acid rain.In addition, sour gas is spontaneous corrosion, and may be to for commercial processes conveying gasThe pipeline of body and other equipment cause negative effect. The example that produces the industrial technology of sour gas comprisesThe steam reformation of coal gasification, gasification of biomass, hydro carbons and the partial oxidation of natural gas or separation. RightEach in these techniques, all wishes remove (purification) or capture sour gas. For example,, when in skyWhile so capturing CO2 in gas process, be not only that CO2 no longer becomes pollutant or no longer causesGlobal warming, it also can be sold for other industry, for example beverage industry, oil reclaim industry and otherGreen energy resource system, for example algae is fixed.
Therefore, improve sorbing material, exist lasting to capture object gas with this sorbing materialDemand.
Summary of the invention
The present invention solves the deficiency that prior art exists, and a kind of sour gas sorbing material is provided, itsMaterial has higher durability and for the good adsorption capacity of acid object gas.
For addressing the above problem, the invention provides a kind of sour gas sorbing material, described adsorption materialMaterial comprises the flat substrates of loose structure, and described base material is activated carbon fiber, the absorption of described base material dippingAgent composition, described adsorbent composition comprises polyamine and the polymer that coexists with polyamine chemical bonding,Described polymer while and described polyamine and the described activated carbon fiber chemical bonding of coexisting; Described polyamine choosingFrom polymine, polyamide amine, polyvinylamine, alkyl amino alkoxy silane, four ethylidene fiveAmine, diethanol amine, diethylenetriamines, penten, tetren-acrylonitrile, N-[(3-Trimethoxysilyl) propyl group]-ethylenediamine, N-[(3-trimethoxysilyl) propyl group]-diethylideneThe combination of one or more in triamine, polyaziridine, described in the polymer that coexists comprise polyolefin-propyleneAcid copolymer and polyurethane.
Described polyolefin-acrylic copolymer comprises the copolymer of ethene and acrylic acid ammonium salt
Due to technique scheme, beneficial effect of the present invention is:
Base material of the present invention is for being activated carbon fiber, and activated carbon fiber is loose structure, can maximum journeyThe reservation adsorbent composition of degree, this adsorbent composition comprises polyamine and with polyamine chemical bondingThe polymer that coexists, has higher adsorption efficiency to sour gas, the cavernous structure energy of activated carbon fiberEnough adsorption capacities of further strengthening adsorbent composition.
