Zusammenfassung:	A slurry bed hydrocracking reaction system and method for heavy oil. A raw-material mixing buffer tank stores and uniformly mixes reaction raw materials; the mixed reaction raw materials enter a raw-oil heating furnace; the heated materials enter a gas-liquid mixer; a hydrogen mixing and heating furnace heats hydrogen and then separately introduces the hydrogen to the gas-liquid mixer and a slurry bed reactor; the gas-liquid mixer mixes the reaction materials with hydrogen, and introduces the mixture to the slurry bed reactor; and the reaction materials and the hydrogen are subjected to a hydrocracking reaction. The vacuum residue conversion rate of the method can reach 90-95% or more, the coking amount of the reaction system is low, and a device can run for a long period. L'invention concerne un système et un procédé de réaction d'hydrocraquage en lit de suspension pour huile lourde. Un réservoir tampon de mélange de matières premières stocke et mélange uniformément des matières premières de réaction ; les m
