FIELD: petroleum processing. SUBSTANCE: raw material, in particular, high-viscosity petroleum residue, is subjected to cracking in tube furnace (first step) and then is transferred into external non-heated chamber (second step). Stream is cooled and fractioned. Invention consists in that, raw material is preliminarily exposed to electromagnetic field with intensity from 0.5 to 1000 V/mm. EFFECT: enhanced process efficiency. 1 dwg, 1 tbl
