1. a Paraffin production method, comprises the following steps:

  • (1) vacuum distillate raw material is mixed by a certain percentage with isopropanol aqueous solution of urea in blending tank, described formerThe initial boiling point of material is 300~

    350 DEG C, and the end point of distillation is 450~

    560 DEG C;

    (2) mixed material of step (1) gained is pumped into double tube reactor, carries out complex reaction, and toward anti-in course of reactionAnswer and liquid adds a certain amount of retarder thinner;

    Adding retarder thinner to refer to divide 2~

    4 times in double tube reactor, point multiple spot adds diluteRelease solvent;

    (3) when reacting final temperature and reaching requirement, the reaction mass that separating step (2) obtains, obtain dewaxing liquid and wax liquid, dewaxing liquidWith wax liquid after washing, then separate flux oil through distillation respectively and obtain low solidifying oil and paraffin.
