Mesophase pitch and continuous preparation system and method thereof

The invention discloses mesophase pitch and a continuous preparation system and method thereof. The method comprises the following steps: carrying out reduced pressure distillation on heavy oil to separate refined components; preheating the refined component, introducing the preheated refined component into a continuous synthesis reactor for reaction to obtain a mesophase pitch crude product, and purifying and post-processing the mesophase pitch crude product to obtain the mesophase pitch product. According to the method, continuous production of the mesophase pitch can be achieved, meanwhile, the coke generation amount can be reduced by accurately controlling the reaction temperature, and the production efficiency of the mesophase pitch is improved. According to the method, the tubular reactor is used for replacing a traditional reaction kettle, the mass and heat transfer process is enhanced, the reaction time is shortened, and the reaction temperature is reduced. In addition, the yield can be quickly adjust
