Claim Text:
1. A method of producing an aromatic hydrocarbon and an olefin, comprising: (a) subjecting an oil including a large amount of a polycyclic aromatic compound having two or more rings to partial hydrogenation under reaction conditions of 310˜360° C., 50˜70 atm, and LHSV (Liquid Hourly Space Velocity) of 0.7˜1.0 hr (b) subjecting the partially hydrogenated component obtained in (a) to catalytic cracking using a catalytic cracking catalyst, to obtain a catalytically cracked component, wherein the catalytic cracking catalyst is provided in the form of a combination of a zeolite molecular sieve having a large pore size of 6.5Å or more and a zeolite molecular sieve having a medium pore size of 5˜6.5Å, and the weight ratio of the zeolite molecular sieve having a large pore size to the zeolite molecular sieve having a medium pore size is 5/95˜95/5; and (c) separating the catalytic cracked component obtained in (b) into (i) benzene, toluene, xylene and a C9+ aromatic hydrocarbon, (ii) an olefin component, and (iii) a residual oil.
