The invention relates to a method to separate temperate coal race component based on the extract and the stripping, which belongs to the separating method of the coal race component. Join the component solvent into the coal sample, agitate it and obtain the extract liquid-solid mixture; Carries on the liquid-solid separation to the extract liquid-solid mixture, obtains the extracted liquid and the gathering excess separately; To gathers the excess water used wash, then the vacuum drying, obtains gathers -odd coal; Joins the stripping medicinal preparation in the extracted liquid, the agitation, obtains the stripping liquid-solid mixture and carries on the liquid-solid separation to it, obtains the solid matter and the wet goods; To solid matter water used wash, dry, obtains the refined coal; The wet goods are two laminations: To a lamination takes off resolve A with the atmospheric pressure distillation, carries on the stripping again to the surplus solution, will produce sticks the thick shape solid, carries on the drying process to it, obtains the caking component; Another lamination is mainly resolved B and the stripping medicinal preparation omnium-gatherum. We bench work skill process is simple, the extract and the stripping process is temperate, the resolved recycle, the reaction process is advantageous for the control, can cause the coal petroleum to separate Cheng Cuiyu the coal, the refined coal, the caking group to classify many kinds of unique race components equally in advance likely.

The present invention discloses a method for preparing cyclohexanone through a cyclohexane liquid-phase oxidation method. According to the method, alcohol ketone from a cyclohexane oxidation reaction sequentially passes through a first rectification tower so as to separate the cyclohexanone product, and passes through a second rectification tower and a third rectification tower so as to separate cyclohexanol, the separated cyclohexanol is added into a dehydrogenation reactor through an alcohol groove to carry out a dehydrogenation reaction, the reaction product from the dehydrogenation reactor sequentially enters a fourth rectification tower so as to separate the component containing the carbon number of less than 6, and enters a fifth rectification tower so as to separate the cyclohexanone product, the tower kettle liquid of the fifth rectification tower is recycled as the feeding material of the second rectification tower, and a light component separation device is arranged after the fifth rectification tower, such that the raw material containing the high light component content is removed in the light component separation device in advance so as to reduce the light component content in the cyclohexanol. The method of the present invention has advantages of simple process, low cost and good light component separation effect.
