Hydrotreating method for heavy oil containing asphaltene

A hydrotreating method for heavy oil containing asphaltene includes contact the heavy raw oil with a catalyst composition containing a hydrotreating catalyst I, a hydrotreating catalyst II and a hydrotreating III under hydrotreating reaction conditions. Calculated by the volume and with the total weight of the catalyst composition as a benchmark, the hydrotreating catalyst I accounts for 5-60%, the hydrotreating catalyst II accounts for 5-50%, and the hydrotreating catalyst III accounts for 10-60%. The hydrotreating catalyst I contains a molding alumina carrier with pore volume of 0.8-1.2 ml / g, specific surface area of 90-230 m , the most probable pore diameter of 20-30 nm and average pore diameter of 25-35 nm, and 10-60 nm pore volume accounts for 95%-99.8% of the total pore volume; and the hydrotreating catalyst II contains a molding alumina carrier containing IVB metal component. Compared with the prior art, the method provided by the invention has better hydrocarbon oil hydrotreatment performance.
