    Information:

    Coal tar is black or black brown viscous liquid, with pungent odor produced during coal carbonization. Coal tar can be divided into low temperature coal tar, medium temperature coal tar and high temperature coal tar according to the dry distillation temperature. The coal tar obtained from coke production belongs to high temperature coal tar. It is one of the purification products of coke oven gas which is condensed and separated in the cooling process of crude gas.

    Coal tar is generally used as a raw material for processing and refining to produce various chemical products. It can also be used directly, such as fuel oil, blast furnace blowout fuel, wood anti-corrosion oil and carbon black raw materials as the ingredients of industrial briquette, type coke and coal based activated carbon.

    Application

    1. Low grade phenol is the main phenolic compound in medium and low temperature coal tar. Low grade phenol can be extracted by chemical extraction as chemical raw material. Distillates from low grade phenol will be a good raw material for producing high sixteen alkane diesel.

    2. Hydrogenation of medium and low temperature coal tar can produce diesel, gasoline and other automotive engine fuel oils and chemicals.

    3. The hydrogenation of high temperature coal tar to fuel oil is more difficult than medium low temperature coal tar. According to the traditional processing technology, the fractions of high temperature coal tar can be separated from a variety of chemical products.
