Patent ID: 7892416

Claim:
A cracking process, wherein cracking is carried out in a cyclone reactor and in a riser with varying diameter and with atomization nozzles under the influence of a rotating and turbulent fluidised energy carrier in the form of fine grained minerals, the fluidised energy carrier in the form of fine grained minerals are put in motion from a regenerator operated at a temperature of 450° C. to 600° C. through two exit lines with outlet under the level of a fluidized bed and are transported to the riser by combustion gases in a fluidization reactor wherein feed oil is preheated by the heat of condensation of the gases and that the oil is atomized in the atomization nozzles having a central inlet for steam, whereby the pressure is preset by springs and the oil in the surrounding chamber is passed to a ring slot where steam hits the oil film and breaks it up into droplets.
