The invention discloses a hydrocracking method for processing a low-sulfur raw material. The method comprises the steps of: hydroprocessing a high-sulfur raw material, and performing gas-liquid separation on a reaction effluent to obtain sulfur-containing hydrogen-enriched gas; hydrocracking low-sulfur raw oil, and performing gas-liquid separation on a reaction effluent to obtain a low-sulfur hydrogen-enriched gas; and mixing the sulfur-containing hydrogen-enriched gas and the low-sulfur hydrogen-enriched gas, selectively performing hydrogen sulfide removal treatment on the gas mixture, and circulating the treated gas mixture to a reactor inlet. According to the invention, two paths of hydrogen-enriched gas of the hydroprocessing process and the hydrocracking process are effectively combined, and the sulfur-containing hydrogen-enriched gas subjected to hydroprocessing is fully utilized to replenish sulfur for a low-sulfur raw material hydrocracking device, so that the problem of sulfur loss of the catalyst during long-term operation of the low-sulfur hydrocracking device is effectively solved. The hydrocracking method disclosed by the invention has the advantages of simplified process flow, low operation cost, low total investment and the like.
