LIGHT RAW MATERIAL PYROLYSIS METHOD Russian patent published in 2006 - IPC C10G9/14 C07C4/04 

FIELD: processes for pyrolysis of light raw materials.

SUBSTANCE: method is realized in pyrolysis furnace designed for heavy raw material. Method comprises steps heating raw material in convection zone; then heating product of convection zone in cracking zone where raw material is converted to products with lower boiling points; cooling product in cracking zone; separating cooled product to several final products. Light raw material is fed through charging opening in convection zone; remaining light raw material is fed to convection zone together with rarefying gas.

EFFECT: possibility for processing different type of raw materials if necessary in the same furnace.
