The invention provides a process for producing needle coke from compounded and blended components such as washing oil, anthracene oil and asphalt in medium and low temperature coal tar as raw materials. The process comprises the steps as follows: raw material pretreatment of the medium and low temperature coal tar, fraction cutting of the components such as the washing oil, the anthracene oil andthe asphalt in the medium and low temperature coal tar, blending of the compounding raw materials, and preparation of the needle coke with thermal polymerization and calcination processes. The ideal raw materials for the needle coke are prepared from fractions of the coal tar by compounding and blending, formation of a wide-area ordered fibrous structure from an intermediate phase can be greatly promoted in a thermal polymerization process by means of reasonable raw material components, and a needle coke product with excellent performance is obtained after calcination.

The invention provides a production method of high-purity conductive carbon black. According to the method, anthracene oil is taken as raw oil for producing conductive carbon black, when the anthracene oil is subjected to heating distillation, the quantity of fractional distillation at 360 DEG C is larger than 68%, and the quantity of fractional distillation at temperature lower than 300 DEG C issmaller than 10%. A carbon black generation reaction is executed in a multi-stage reaction furnace under the condition that the temperature of a reaction stage of the reaction furnace is kept at 1700-1760 DEG C; pure soft water is taken as process quenched water to terminate the carbon black cracking reaction and serves as secondary quenched water, and impurity-free high-purity powdery carbon black is obtained; the pure soft water as granulation water is mixed with an adhesive in a static mixer, the impurity-free high-purity powdery carbon black is mixed for granulation with the granulation water and the adhesive in a granulator, a small amount of diesel oil is added to serve as a granulation aid in the granulation process, and high-purity conductive carbon black particles are obtained. The particles produced with the method have high dispersity, low resistance, stable structural performance and high purity, are uniform and are conveniently produced and processed by a customer.

The invention relates to a method for measuring coal tar trimixed naphthalene oil, comprising the following steps: (1) weighing the dehydrated coal tar whose quality is X; (2) putting the coal tar into a distillation bottle of a fractionation device, and The fractionation device is connected and assembled; (3) start heating the retort in step (2), cut off the distillate segment with a temperature of 180-250°C and weigh the weight X1 of the distillate and measure the purity Z; (4) continue to reheat the retort The coal tar in the heating is heated until crystallization occurs in the distillate, and the heating is stopped, the temperature at this time is recorded, and the weight X2 of the distillate in the receiver at this time is weighed; (5) according to step (3) and step (4 ) fraction weight calculation of the content Y1 of naphthalene in coal tar and the content Y2 of three mixed naphthalene oils. The method for measuring coal tar trimixed naphthalene oil predicts the yield of trimixed naphthalene oil in actual production, can reduce the content of anthracene oil in the trimixed naphthalene oil, and improves the purity of the trimixed naphthalene oil, which can be used to guide practice Production.

The invention discloses a method for hydrogenating deeply-drawing carbolineum. The two-section hydrocracking process is applied to the method. The deeply-drawing carbolineum passes through a hydrorefining reaction area firstly to obtain a hydrorefining product; the obtained hydrorefining product is separated to obtain a liquid phase product which enters a hydrocracking reaction area, is sequentially contacted with a hydrorefining catalyst, a hydrogenating residual carbon removing catalyst and a hydrocracking catalyst for reaction to obtain a hydrocracking product; and the hydrocracking product is separated to obtain gasoline and diesel oil fractions. By using the method, the deeply-drawing carbolineum is processed, the range of raw materials is widened, the deeply-drawing carbolineum can be converted to maximum extent, the yield of lightweight fuel oil can be improved and the added value of carbolineum is improved; meanwhile, the activity of the hydrocracking catalyst can be effectively protected, so that the device can operate for a long period.

The invention discloses a device and a process for preparing and producing oils for processing coal tar. The device comprises an oil distributing tank, an oil gas condenser, an oil gas capturer, an oil distributing conveying pump, an oil distribution gasification and condensation cooler, a waste gas cooler and the like. The process is as follows: anthracene oil is pumped to a shell side of the oil gas condenser at the upper part of the oil distributing tank, enters the oil gas capturer, then enters the shell side of the oil gas condenser from top to bottom, enters the oil distributing tank, then is mixed with medium-temperature asphalt in the oil distributing tank, and then is circulated to the oil distributing tank through the oil distributing conveying pump and the oil distribution gasification and condensation cooler; oil generated during the oil distribution sequentially passes through the oil gas condenser, the oil gas capturer and the waste gas cooler; the anthracene oil is completely recycled, and waste gas after the anthracene oil is removed is washed with gas absorber oil and then discharged into atmosphere; and the final product is conveyed to a product tank through a product conveying pipeline. The device and process thereof are simple and convenient for operation; and the obtained product has the advantages of stable quality, good product quality, high yield and nopollution during the production.
