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:How much is the standard coal coefficient
Table 605 - 1 energy factorElectricity: 1 kwh = 0.1229 x 10-3 tons of standard coal water: 0.0857kgce/t
Q:Soft, hard charcoal, what is the difference?
The painting was most concentrated soft carbon black, but easily broken and consumed quickly, generally used to screen the color of the deepest parts, all the properties of hard carbon in the opposite, between the carbon is between the first two, I use Marley, Voltaire (wood) and the Chinese in their carbon and hard carbon, charcoal for the soft - hard carbon strip, but is very strong, can be used for color, in fact only charcoals can
Q:What are the advantages of natural gas from coal in terms of heat
1 high calorific value of natural gas, so the heat of the combustion unit is large, more suitable for the need to produce high temperature, combustion efficiency is much higher than coal
Q:How is the charcoal burning out
The trees cut into sections, lit in a kiln, burning to a certain extent, closed air into the kiln, waste heat to heat water and carbonization of wood, wood tar is leavened, carbonization of wood charcoal as. This is similar to the past when the family of firewood burning charcoal.Now there is the use of wood chips and other waste processing mechanism of charcoal, the waste pressing forming, indirect heating in the furnace for carbonization, these raw materials carbonized into charcoal.The quality of charcoal can only be used according to different quality indicators. Usually, we measure the quality of the charcoal mainly from the moisture content, volatile fraction, ash content, fixed carbon content and calorific value
Q:Activated carbon mask can be used for how long to kill
Do not use in the oil gas environment (the above products apply to rubber, fur manufacturing, battery, chemical, mining, petroleum, nuclear engineering, shipbuilding, crafts, crystal, papermaking, brewing, agriculture, petrochemical, environmental sanitation, glass manufacturing and other industries).
Q:Well log interpretation
As well as the "four low" characteristics: low natural gamma, low compensation density, low cross section, low acoustic impedance, and dark color;
Q:Other related to coal oil
According to expert estimates, when the price of crude oil in more than 28 U.S. dollars, coal oil in the economy is more cost-effective; below this price, coal oil is not worthwhile. Therefore, in the middle of the 80s to the middle of the 90s, international oil prices have been at a low level, coal oil will naturally not be taken seriously. However, the technology has been quite mature, can be said to have a ready pen, as long as the needs of the market, can undertake large-scale industrialization. Until the last two years, international oil prices continue to rise, coal oil re put on the agenda by countries. The United States began to engage in indirect liquefaction last year, France, Italy began to cooperate in R & D. But from the start of the project to start the construction of at least 5 years of preparation time, and oil price changes frequently, while low, people tend to make decisions about the response lag.
Q:Activated carbon can prevent radiation?
Activated carbon has the function of radiation protection, but not all of the activated carbon has, but at a certain temperature calcined with radiation protection function. The basic condition of shielding electromagnetic wave is conductor. The smaller the resistivity of a substance, the better its conductivity. Good conductor can be effective, practical significance of shielding electromagnetic wave. At present, the overall market for activated carbon is more chaotic, high temperature carbon, medium temperature carbon and even low carbon cohabitation,
Q:How to burn charcoal barbecue?
Mechanism carbon igniting methodThe best and fastest ignition method is to use the fruit above the ignition mechanism of carbon carbon (faster than gas burning), if there is no fruit with solid alcohol carbon directly ignited, can refer to the picture below, can also be placed on more closely than the picture, and then several layers, in position 2 A piece of alcohol, alcohol can be ignited, so put to have better air circulation for carbon faster in the fire is not extinguished before the fire, not to stir up the same as charcoal carbon, white to barbecue. The mechanism of carbon burning time is 2.5 times of fruit carbon. This picture is just a description of the method of carbon can be a little short of some.
