Processing method of vacuum residue high-yield chemical raw materials

The invention discloses a processing method of a vacuum residue high-yield chemical raw material. The method comprises the following steps: mixing a vacuum residue raw material with hydrogen, entering a fluidized bed hydrogenation reaction zone, carrying out a hydrogen thermal cracking reaction, and carrying out separation and fractionation to obtain a gas fraction, light distillate oil, wax oil and tail oil; the initial boiling point of the light distillate oil is 50-80 DEG C, and the final boiling point of the light distillate oil is 280-340 DEG C; in the presence of hydrogen, the light distillate oil and hydrogen are mixed and sequentially enter a first hydrocracking reaction zone and a second hydrocracking reaction zone for reaction, an obtained second hydrocracking product is subjected to separation and fractionation, and gas, light naphtha, heavy naphtha and tail oil are obtained; the tail oil and hydrogen are mixed and enter a third hydrocracking reaction zone, and an obtained third hydrocracking produ
