Q:What is bituminous coal, coal tar distillation of coal products are coke and coal tar, these toxic coal tar in general how to deal with, so that non-toxic?

Paste, to see if there is no useCoal tar pitch Coal PitchAll kinds of natural organic matter (such as coal, wood, peat or shale) in air condition, the viscous liquid, the coking distillation, called the "tar tar". Then after further processing by viscous liquid that semi-solid products called "tar". Usually the tar processing of raw materials for coal, it is referred to as the "coal tar pitch", referred to as the "pitch".

Q:Tea and activated carbon which adsorption effect is goodSuch as the title

The activated carbon particle size has an effect on the adsorption capacity of activated carbon. In general, the smaller the particle is, the larger the filter area. Powdered activated carbon total area is the largest, the best adsorption effect. The adsorption capacity of activated carbon is compared with no gap, the total area is very small, not tea.

Q:How to calculate the investment of coal

Is based on the design of the mine production capacity and construction investment to calculateThe formula is as follows:Tons of coal investment (yuan / T) = total investment (yuan) / design production capacity (T)

Q:What is the specific coal chemical

Coking technology is one of the most important technologies in the coal chemical industry. Coal gasification plays an important role in the coal chemical industry, for the production of all kinds of fuel gas, clean energy, is conducive to the improvement of people's living standards and environmental protection; synthesis gas production is the synthesis of liquid fuel and other raw materials. The direct liquefaction of coal, that is, the high pressure hydrogenation liquefaction of coal, can produce artificial petroleum and chemical products. In the oil shortage, coal liquefaction products will replace the current

Q:Bamboo charcoal bag placed in the room

If the living room floor is not a collage, but with adhesive, bamboo charcoal package can be placed in the corner of the room. Or the living room furniture is the election of the board, you can put the bamboo charcoal bag in the drawer of furniture

Q:I use a activated carbon respirator (Miguel card please see picture), but the product did not specify how long you can use, only that can smell the poisonous gas is to be replaced, but the smell is not good, for fear of insecurity, would like to ask if there is a smell of paint in this environment. How long you can use mask is safe, by the hour

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:The difference between activated carbon and charcoal?

On the market and other products in addition to taste comparison: currently on the market are mainly chemical, biological, photocatalyst products, these products prices are generally very expensive, has certain use conditions, such as chemical can remove formaldehyde, but the specific effects of the use of the customer is not clear, is completely convinced of the promotion personnel, and activated carbon in addition to flavor, is affordable, easy to use, no pollution, no side effects, the effect is ideal, activated carbon masks during the SARS example is the most simple, no one will suspect activated carbon masks and gas masks, and activated carbon products with low cost and convenient long-term.

Q:Activated carbon is what? What use does it have?

Using this principle, we can quickly and effectively remove harmful substances in the air, odor, etc., so that the air can be a direct and rapid improvement. Like activated carbon is very good, can effectively remove formaldehyde and other harmful gases.

Q:Powdered activated carbon and globular activated carbon which is good

Shape does not represent the performance of activated carbon, because the activated carbon industry is not the same as the number of activated carbon has a special shape requirements!

Q:Where can I find charcoal?

Burn wood for charcoal. But it's a waste of wood
