Q:Straw briquetting machine how much money?
The straw fuel "refers to the corn straw, wheat straw, rural cotton stalk, rice straw, rice husk, peanut shell, corn cob, branches, leaves, sawdust and other crops and solid wastes as raw material, after crushing, pressing densification molding, namely" straw fuel". The characteristics of forming straw fuel "after the straw fuel, small volume, large burning resistance, convenient storage and transportation, the volume is only equivalent to the original straw 1/30, is 10-15 times the same weight of straw, the density of 0.9-1.4g/cm3 calorific value can reach 3500-5500 kcal, is of high volatile solid fuels issued a.
Q:What is the bulk density of activated carbon?
In addition to activated carbon carbon, also contains two kinds of admixtures: one is the combination of chemical elements, mainly hydrogen and oxygen, these elements are due to incomplete carbonization and the residue in the carbon, or in the process of activation, non carbon and activated carbon surface chemical foreign combination, such as the use of water vapor when activated, the surface of the active carbon is oxidized or water vapor oxidation; another kind of admixture is ash, it is part of the inorganic carbon in ash; activated carbon is easy to cause two pollution.
Q:How to use activated carbon to filter liquor
Look at the density of activated carbon pore number, the adsorption performance of activated carbon is higher, more crisp, the relative density is low, will feel lighter in weight in the case of packaging, the volume is also bigger. The proposed purchase of small density, light touch, such as the weight of large volume of activated carbon products.
Q:Activated carbon is what?
The chemical formula of activated carbon is C, activated carbon has a strong physical adsorption, adsorption of organic compounds can be achieved to remove the effect
Q:New activated carbon, taste a little pungent, is it normal?
Home in addition to taste activated carbon, also known as domestic activated carbon, as the principle of physical adsorption, in the process of action, relying on the air as a medium, the adsorption of harmful substances in the air, it is defined as passive air purification materials. A common type of air purification materials, mainly used for adsorption of trace toxic gases in the air, ammonia, formaldehyde, benzene can be refurbished odor adsorption, no pollution, non-toxic, no side effects, safe and reliable.
Q:How coal and oil are formed
Oil is the raw material of biological bodies, biological cells contain fat and oil, fat and oil is composed of carbon, hydrogen, oxygen and other 3 elements
Q:Coal is a kind of coal called "coal", what is the coal ah
The final coal is the smallest particle of coal, which is similar to powder after sieving.
Q:The necessity of power coal washing
In the coal ash, sulfur, phosphorus and other impurities are harmful, so try to get rid of the impurities, it has very important significance to improve the coal use value. Effective method is to get rid of impurities. Coal coking coal washing and processing must pass through this point, people have a more comprehensive understanding. However, with the necessity of coal washing power, is not yet widely known in large numbers.x0d
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
China has the advantage of coal to oil, but will not become the main direction of oil production experts believe that in China to engage in coal oil has a significant advantage. The rich coal less oil in recent years, with the development of economy, crude oil imports increased year by year, from 1993 to 2003 10 years, an average annual increase of more than 15%, import dependence is more and more high. 10 years, China's crude oil imports increased by 9.18 times a year to spend a lot of foreign exchange. Due to rising oil prices, in 2004 more than 55 billion yuan of imported crude oil last year. Therefore, experts believe that, from the strategic point of view of China's energy security, but also should strive to find ways to solve the problem of long-term supply of energy from the diversification, and coal oil is one of the feasible ways.
