摘要： A process for the thermal cracking of heavy oils with a fluidized particulate heat carrier is carried out while recovering particles of the heat carrier accompanied by a stream of the reaction product by means of a cyclone and a gravitational separator, returning the particles of the heat carrier recovered by the cyclone directly to the reactor and returning the particles of the heat carrier recovered by the gravitational separator to the reactor in the form of suspension in a cracked oil.

摘要： In the process of thermally cracking a heavy hydrocarbon oil by feeding said oil into a fluidized bed reactor as a high-velocity atomized gas stream by blowing said oil therein from a gas-mixing type nozzle along with an atomizing gas and carrying out the thermal cracking of the oil at above 500.degree. C., the improvement which comprises blowing in an inert gas to the eddying part formed in the environs of said atomized gas stream in said fluidized bed reactor thereby blocking the formation of eddies to thus prevent the accumulation of coke deposits on the outside wall of said nozzle and the walls of the fluidized bed reactor in the vicinity of said nozzle.
