What is the current status of carbon dioxide capture technology and how is it compared to plants that absorb carbon dioxide?
Landlord can check their own literature what. = For example, I think this review is very good. The Although it does not include relatively new progress, but I think it is quite good. The You see such an answer to the efficiency of how low ah not as good as their own to find the literature to see right
Why not ah?
Ethylene is not a derivative of hydrocarbons, ethylene Chemical formula: CH2 = CH2
China's largest asphalt production base where
Coal tar pitch is a byproduct of coking, that is, the black material that remains in the distillation kettle after distillation of the tar. It is only fine with the physical properties of refined tar, there is no obvious boundaries, the general division method is to specify the softening point at 26.7 ℃ (cubic method) for the following tar, 26.7 ℃ above the asphalt. Coal tar pitch mainly contains volatile anthracene, phenanthrene, pyrene and so on. These substances are toxic, because the content of these components are different, the nature of coal tar pitch is also different. The change of temperature has great influence on coal tar pitch, which is easy to brittle in winter and easy to soften in summer. Heating with a special smell; heated to 260 ℃ in 5 hours later, it contains anthracene, phenanthrene, pyrene and other ingredients will be volatile.
