Abstract
Disclosed is a process for the thermal cracking of heavy oils, which comprises a thermal cracking step of contacting a heavy oil with a fine powder of a porous material fluidized by a fluidizing gas to mainly obtain a light oil and a regenerating step of gasifying and removing coke adhering to the fine powder taken out from the thermal cracking step while fluidizing the fine powder by a molecular oxygen-containing gas and a steam-containing gas, the fine powder being circulated between the two steps, wherein fine spherical particles having a pore volume of 0.2 to 1.5 cm.sup.3 /g, a specific surface area of 5 to 1500 m.sup.2 /g, an average pore size of 10 to 10,000 .ANG. and a weight average size of 0.025 to 0.25 mm, in which these properties are stably maintained at the temperature adopted for the thermal cracking, are used as the fine powder, and a hydrogen gas is made present at the thermal cracking step, the partial pressure of hydrogen is maintained at about 0.5 to about 5 Kg/cm.sup.2 and the total pressure at said step is maintained at about 1 to about 10 Kg/cm.sup.2 -G.
