Poor quality heavy oil and/or poor quality residue oil processing method

The present invention relates to a poor quality heavy oil and/or poor quality residue oil processing method, which comprises that poor quality heavy oil and/or poor quality residue oil is conveyed into a slurry bed reactor and contact a hydrogenation catalyst, a first hydrogenation reaction is performed, the obtained product is conveyed into a high pressure separator, separation is performed, and a hydrogen-containing gas is obtained from the top portion of the high pressure separator, a liquid component is obtained from the middle portion, and a heavy material is obtained from the bottom portion; and the liquid component is conveyed into a fixed bed reactor, a second hydrogenation reaction is performed, at least the part of the material obtained from the outlet of the fixed bed reactor returns to the slurry bed reactor, and the conversion depth of the poor quality heavy oil and/or poor quality residue oil does not exceed 50% due to the first hydrogenation reaction condition. According to the present inventio
