PROBLEM TO BE SOLVED: To provide a method where heavy thermal cracking oil and an extract which are hardly converted to light oils are cracked without generating cokes. SOLUTION: In the method for cracking hydrocarbon oil, at least one kind of hydrocarbon oil selected from heavy thermal cracking oil and an extract is subjected to cracking reaction at 280 to 580°C under 3.0 to 20.0 MPa in the absence of oxygen and hydrogen. In the method, the hydrocarbon oil is subjected to cracking reaction preferably for 30 sec to 60 min. COPYRIGHT: (C)2009,JPO&INPIT
