Embodiment Construction

[0017] The solutions and effects of the present invention will be described in more detail below in conjunction with the drawings and embodiments.

[0018] like figure 1 As shown, in the following preferred embodiments of the present invention, the purified washed oil 1 is first mixed with hydrogen 2 and enters the hydrogenation reactor 3 to obtain the hydrogenated oil 4 and enters the high-pressure separator 5 for gas-liquid separation, and the obtained gas 6 is recycled after being pressurized by the circulating hydrogen compressor 7, and the separated liquid 9 enters the stripping tower 10 (or fractionating tower) for fractional distillation according to the amount of gasoline (naphtha) to obtain gas products, gasoline (naphtha) 11, Diesel 12.

[0019] Table 1 lists the properties of the washing oil raw material used in the following examples 1-4.

Abstract

The invention discloses a method using the washing oil produced by the coal tar to prepare gasoline and diesel with hydrogen, which is essentially characterized in that the washing oil produced during the coal carbonization process is mixed with the hydrogen to obtain the hydrogenation oil through a reactor filled with protective agent, demetalization activator, hydrogenation refined activator and / or hydrogenation modified activator; the hydrogenation oil enters into a high-pressure separator; and the hydrogen obtained at the upper part is recycled to use, and the materials at the lower part are stripped or fractionated to obtain gasoline (naphtha) and diesel. The method can effectively produce high-quality and clean diesel products with washing oil.

Description

technical field [0001] The invention relates to the field of production of high-quality gasoline and diesel products, in particular to a method for preparing gasoline and diesel by hydrogenation of washed oil produced from coal tar, that is, the washed oil is used as raw material oil through hydrofining widely used in the field of petroleum processing method to prepare gasoline and diesel oil, thereby not only cleaning up the use of washing oil, but also broadening the source of motor fuel oil. Background technique [0002] With the development of the economy and the progress of the society, the world's demand for motor fuel is increasing. At the same time, environmental protection regulations are becoming more and more stringent, and the requirements for the quality of motor fuel are also getting higher and higher. However, due to political reasons and restrictions on the amount and total amount of oil resources extracted, the price of crude oil continues to remain high, re...
