ABSTRACT:
A process for producing olefines by using a fluidized bed of coke particles rovided in each of a reactor and a heater, circulating coke particles through the reactor and the heater, heating the coke particles by a combustion of fuel and if desired, a part of the coke particles in the heater, thermally cracking a heavy oil with a heated coke particles as a heat carrier in the reactor, the improvement which comprises a distillation residue is converted into a high-temperature, low-calorie gas in a combustion chamber, and the coke particles is heated with the gas in the heater, further an increment of coke deposited on a surface of the coke particles is burned by blowing air to the heater.
