PROCESS FOR THERMAL CRACKING OF HEAVY OIL

摘要

The heavy oils contg. non-vaporisable, high-mol. wt. hydrocarbons are thermal cracked in the presence of steam by passing a fluid mixt. of heavy oil and steam into the tubuler thermal cracking zone without the depositing compound at the condition of the temp. of 800-1100≦̸C, the pressure of 0-5 kg/cm2G, the flow velocity of 10-100 m/sec and the dwelling time in the zone of the fluid to be at least 0.2 sec.
