Q:What is the proportion of dry activated carbon
Activated carbon, activated carbon. It is a black powder or lump, granular, honeycomb amorphous carbon, also has arranged crystal carbon. Activated carbon in addition to carbon elements, but also contains two kinds of admixture
Q:There are several categories of coal sampling machine
Peat flammability, easy combustion, strong reactivity, low sulfur content, low ash melting point, but lower mechanical strength. Therefore, the use of peat is not high value in industry, it is not suitable for long distance transportation, generally only as a local fuel use. Areas located in the southwest provinces and Zhejiang (West Lake coal).In June 2009, the State Administration of Quality Supervision Inspection and quarantine and the National Standardization Management Committee jointly issued the "national standard" classification of coal Chinese (GB/T 5751-2009), on the basis of dry ash free volatile Vdaf, dry ash free hydrogen bond index G, Hdaf, Y, glial layer maximum thickness of Oaxaca expansion degree B, low rank coal light the rate of P, and ash free calorific value Qgr, MAF 7 classification index, coal will be divided into 14 categories. The lignite, long flame coal, non caking coal and weakly caking coal, 1/ 2caking coal, gas coal, gas coal and 1/3 coking coal, coking coal, lean coal, lean coal, lean coal and anthracite.According to the different classification of the rock structure, can be divided into candle coal, silk carbon, dark coal, bright coal and mirror coal. Contains more than 95% vitrinite for coal, coal surface light, solid structure, containing vitrinite and light for plastid clarain, containing coarse body as dark as coal, with silk silk carbon, formed by many microspores formed for the microsomal cannel.
Q:What is the difference between activated carbon and charcoal?
Activated carbon is a kind of porous carbon, according to the adsorption characteristics of activated carbon, activated carbon is mainly used to remove pollutants in water, decolorization, filtration and purification of liquid, gas
Q:Carbon powder color Potassium Permanganate and the same color of manganese dioxide
Manganese dioxide is a black orthorhombic crystal or brownish black powder. Relative density 5.026. Insoluble in water and nitric acid, soluble in acetone. Brown solution and cold hydrochloric acid reaction of high manganese chloride, the chlorine released from heated and formed in hydrogen chloride, heated to 200 degrees Celsius, generating three two and four three manganese oxide manganese oxide. To produce manganese sulfate in the concentrated sulfuric acid. Generation of manganate and caustic soda and oxidant eutectic. With sulfur heating, the formation of sulfur dioxide and manganese sulfide. Reduction of manganese to carbon at high temperature. 420 DEG C decomposition deoxidization, the formation of low manganese oxides
Q:What is the mineral composition of coal?
The composition of coal is mainly composed of organic matter, which is mainly composed of carbon, hydrogen, oxygen, nitrogen and other elements. There are ten kinds of elements in coal, but the elements of coal are usually composed of five elements, namely carbon, hydrogen, oxygen, nitrogen and sulfur. In coal, the content is very small, a large variety of other elements, generally not as the composition of the elements of coal, but only as an element or trace elements in coal.
Q:Coal quality test, Mt, Mad, Aad, Vad each represents what mean
The first indicator: moistureThe moisture in coal is divided into internal water, external water, crystal water and waterToo much water in the coal, is not conducive to processing, transportation and so on, combustion will affect the thermal stability and thermal conduction, coking will reduce the coke yield and extend the coking cycleNow we often report the moisture index:
Q:Trouble who told me the coal index of English code
Coal five common indicators for you to do reference.The first indicator: moisture.The moisture in coal is divided into internal water, external water, crystal water and water.The water is too large, is not conducive to processing, transportation, combustion will affect the thermal stability and thermal conduction, coking will reduce the coke yield and extend the coking cycle.
Q:The coal industry often crushed to the full combustion, its purpose is to
A, the coal industry often crushed, increasing the contact area of coal and oxygen, can make full combustion of coal, reduce coal waste, so the correct option.
Q:1 tons of standard coal to produce heat energy equal to how much Coke
(7 million calories per kilogram of calories to calculate: 1 thousand card =4180 joules);
Q:70 square meters of housing need to buy how much activated carbon
The quantity of activated carbon should be determined according to the content of formaldehyde and the quality of activated carbon.
