Abstract: An improved process for thermal cracking of a heavy oil comprising a step of thermal cracking of the heavy oil in contact with a fluidized bed of heated fine particles and a step of gasification of the coke which has deposited on the fine particles used in the thermal cracking, which gasification is conducted on the fine particles withdrawn from the thermal cracking step by contacting the particles with gas containing molecular oxygen while the particles are fluidized by the gas, the steps being practiced while the fine particles are circulated therebetween is disclosed. The improvement comprises a use of fine particles of a porous material, and conducting the gasification under specified conditions and so as to produce a product gas which is highly reducing. Production of reducing gas at the gasification step whereby the used fine particles are regenerated for further use in the thermal cracking step results in converting by reduction heavy metals which have come from the heavy oil as the feed stock and are accumulated on the fine particles used into a state less harmful for the thermal cracking where the regenerated fine particles are used.

Abstract: A two-step process for producing microspherical pitch or green coke particles having an average diameter of 30-200 .mu.m from finely divided petroleum or coal pitch having a softening point of 60.degree.-220.degree. C. and a fixed carbon content of 40-75 wt %. In the first step the material pitch is fluidized in the stream of a gas substantially inert to the pitch at a temperature of 100.degree.-800.degree. C., the mixed stream is rapidly cooled to 30.degree.-400.degree. C., and microspherical pitch particles are recovered with or without separate recovery of an oily product. In the second step the pitch spheres are further subjected to thermal cracking and polycondensation by use of a fluidized bed at a temperature of 350.degree.-520.degree. C. for a retention time of 1 min. to 3 hours, and microspherical green coke particles and a light cracked oil are recovered. In both steps a pressure between the ordinary level and 10 kg/cm.sup.2 is used.
