HEAVY HYDROCARBON STOCK HYDROCRACKING PROCESS AND REACTOR Russian patent published in 2008 - IPC C10G47/22 

FIELD: petroleum processing and petrochemistry.

SUBSTANCE: hydrocracking of heavy hydrocarbon stock is accomplished by feeding preheated feedstock and hydrogen or hydrogen-containing gas to reactor, heating the charge in reactor, and discharging cracking products, which are passed to separation stage. Reactor has two convection chambers with convective and radiation coils disposed therein. Hydrocracking is carried out, in particular, in reactor radiant coil zone with variable-cross section tubes allowing flow rate 50 to 310 m/s at 440-500 flow rate 50 to 310 m/s at 440-500°C.

EFFECT: increased productivity and efficiency of process.
