Q:Where is the main use of coal?
(2) coking coalAlthough our country is rich in coal resources, coking coal resources are relatively small, coking coal reserves account for only 27.65% of China's total coal reserves.Coking coal includes coal (13.75%), (3.53%) coal, coking coal, lean coal (5.81%) (4.01%), the other is divided into grades of coal (0.55%); non coking coal includes anthracite (10.93%), coal (5.55%), alkaline coal (1.74%) do not pay, coal (13.8%), coal (12.52%), brown (12.76%), natural coke (0.19%), not the grades of coal (13.80%) and grade of coal is not clear (1.06%).
Q:Bamboo charcoal package is valid
Personally think that should still haveThe adsorption capacity was related to the particle size, and the adsorption rate of fine carbon was higher than that of the 80 mesh, while the bulk carbon was the slowest.Deodorant bamboo charcoal bag placed in the refrigerator, wardrobe, shoe cabinet, toilet, car and other places, every 2~3 months in the sun exposure once, you can get rid of bamboo charcoal adsorption of moisture and odor, to maintain a good function of bamboo charcoal. Charcoal bag placed more than one or two years, the demolition of the bamboo charcoal particles buried in the soil, used to improve soil activity, prevent the occurrence of pests and diseases, promoting plant growth.
Q:What is the thermal stability of coal
The thermal stability of coal refers to coal in high temperature combustion or gasification process on the stability degree of heat, which is coal under high temperature and keep its original size properties. Good thermal stability of the coal, to its original size. Combustion or gasification but not broken into small pieces in the combustion or gasification process, or broken less; and poor thermal stability in coal combustion or gasification process is rapidly split into small pieces or coal. This light is slagging in furnace, increasing resistance and bring out the material, reduce the combustion or gasification efficiency, heavy damage to the entire gasification process, and even cause shutdown accidents. Therefore, there are requirements of coal enough thermal stability.
Q:What are the types of coal
Bituminous coal: generally granular and small shape, there is powder, black and shiny, delicate texture, containing more than 30% volatile, ignition temperature is not too high, is easy to ignite; carbon content and calorific value of burning high, fast ignition, long flame, there are a lot of black smoke, burning a long time; most of coal are sticky, easy slagging combustion.
Q:General charcoal and activated carbon what is the difference?
That is the sum of 1 grams of carbon surface area and pore area. All the bamboo charcoal firing temperature is over 500 DEG C, the specific surface area between 150 square meters to 350 square meters of /g /g; and by physical or chemical methods are made of activated carbon, the specific surface area can reach 900m2/g or even 2000m2/g. Because of the more developed pore structure and the larger specific surface area, the adsorption function is stronger, so the overall ratio of activated carbon adsorption of bamboo charcoal is more.4, hardness difference of bamboo charcoal density, high hardness, non friable, suitable for wearable textile products; and the active carbon hardness of different materials differently, coconut shell activated carbon high hardness with the production of activated carbon, bamboo has light weight, thin, fragile, so it is not suitable for high wear resistance products.
Q:The difference between graphite particles and activated carbon particles
Belong to the six party system, with a complete layer of cleavage, cleavage surface with molecular bonds, the molecular attraction is weak, so its natural floatability is very goodActivated carbon and activated carbon black. Black amorphous carbon powder or granular activated carbon. The main components other than carbon and oxygen, hydrogen and other elements. The activated carbon in the structure due to crystallite carbon is irregular, the cross connection between pore,
Q:I would like to ask what is the pit coal?
Direct delivery of coal from coal mine pit. That is to say, we do not have to go through the delivery of coal that is rightIt is generally said that the fresh directly out of the mouth
Q:How much is the standard coal coefficient
Liquefied petroleum gas: 1 kg = 1.7572 x 10-3 tons of standard coalThis is a number of energy conversion into standard coal coefficient, the new water coefficient is 0.0857kgce/t so 1t water is converted into standard coal should be: 1*0.0857=0.0857kg standard coal
Q:What is the meaning of coal m40.m10
After the completion of the test, the sieve with the pore diameter of 40mm and 10mm sieving, the percentage of M10 particles larger than 40mm is M40, less than the percentage of 10mm particle size.
Q:Powdered activated carbon and globular activated carbon which is good
These two kinds of activated carbon can not say who is good or bad, can only say that you are used where, what to do with. Like the powdered activated carbon used in food decolorization, more sugar decolorization field. The spherical activated carbon is used for solvent recovery, air purification up to. These two products have different uses. Corresponding products must be used for different purposes.
