PURPOSE:To obtain high-quality petroleum in high yield with both small amounts of coke and cracked gas generated, by bringing heavy oil into contact with finely spherical particulate porous matter with each specific range of pore size and specific surface area to perform thermal cracking under both specific hydrogen partial pressure and total pressure. CONSTITUTION:The objective cracked gas can be obtained by brining heavy oil into contact with finely spherical particulate porous matter with pore volume 0.2-1.5cm<3>/g, specific surface area 5-1,500m<2>/g, average pore size 10-10,000Angstrom and weight-average pore size 0.025 -0.25mm to perform thermal cracking under hydrogen partial pressure 0.5-5kg/cm<2> and total pressure 1-10kg/cm<2>-G. The particulate matter, taken out of the above thermal cracking process is subjected to reclamation by removing the coke attached on said matter by gasification while fluidizing the matter by molecular oxygen-contg. gas and water vapor- contg. gas. The thermal cracking is carried out while cycling this particulate matter between the thermal cracking and reclaiming processes.
