Background technology
Hydrargyrum is a kind of poisonous trace heavy metals, has effumability, persistency, biological accumulation, biological and human body is produced toxic action, is widely used in commercial production, and the life with us is closely related, and whole world mercuric pollution treatment is extremely urgent.Hydrargyrum is discharged in environment by nature and mankind's activity, wherein based on anthropogenic discharge.Maximum mankind's activity emission source is the burning of Fossil fuel, particularly burning of coal.China is big coal country, is also coal-fired big country simultaneously, and energy resource consumption is mainly based on coal, and wherein coal-burning power plant accounts for significant proportion.Along with expanding economy, the continuous enhancing of electricity needs, the preventing and treating of coal-fired flue-gas mercury pollution faces huge challenge.
In coal combustion flue gas, hydrargyrum is primarily present three kinds of grown forms: zero-valent state hydrargyrum (Hg0), oxidation state hydrargyrum (Hg2+) particle mercury (Hg (p)).Under hot conditions, mercury compound is converted into zero-valent state hydrargyrum, and this is mainly due to the relatively low heat stability of oxidation state hydrargyrum, when temperature is more than 500～600 DEG C, is little to exist.Therefore, Hg0It it is the main form that in coal combustion flue gas, hydrargyrum exists.Hg (p) can be removed by conventional pollutant catabolic gene equipment, such as inertial dust separator, electrostatic precipitator (ESP) or sack cleaner, and gaseous state Hg2+Soluble in water can be removed by wet type fume sweetening device.Wherein Hg0Due to its high volatility and the slightly solubility in water, existing flue gas purifying equipment is difficult to remove it, and is that gas mercury Environmental capacity is crucial.
Coal-fired flue gas mercury removal is the most extensive with the research of demercuration technology after burning, predominantly: adsorbent demercuration and flue gas demercuration new development-gaseous state nonvalent mercury oxidation.Typical adsorbent is activated carbon, flying dust, Ca-base adsorbent, although activated carbon is higher to the adsorption rate of hydrargyrum, but the problem such as somewhat expensive that there is low capacity and injection technique due to it, limit its development and application.And flying dust and Ca-base adsorbent need to improve for flue gas demercuration efficiency.Research and development have strong absorption and the catalyst of catalytic capability, promote to be insoluble in water in flue gas, the nonvalent mercury of high stability is oxidized to the main flow that bivalent mercury soluble in water is current coal-fired flue-gas Mercury vacancy technology.Predominantly SCR catalyst, transition-metals and their oxides catalyst, noble metal catalyst and terres rares catalyst etc., but for cheap and easy to get, specific surface area is big, adsorptivity is strong, and less at the catalyst preparation research that attapulgite is base material of Jiangsu scope rich reserves.
In recent years, the use of green solvent ionic liquid has obtained paying close attention to widely.Eutectic mixture based on choline chloride (ChCl) has higher ion concentration, compared with most molecular solvent, has uncommon solvent properties, is also the most green medium.When ChCl and urea mol ratio are 1:2, the mixture of ChCl-carbamide demonstrates good congruent melting effect, and its fusing point is 12 DEG C, lower than the mixture fusing point of other ChCl-carbamide.As a kind of acceptant solvent of environment, ChCl-carbamide eutectic mixture has been widely used in different field, such as microporous crystalline zeolite, chemical reaction etc., has certain potentiality for other process studies.
