PROCESS FOR CONVERTING NAPHTHA

摘要

Disclosed is a process for converting naphtha. Lower olefin, light aromatic hydrocarbon, and gasoline with high octane number are produced through combining catalytic cracking of naphtha with steam cracking of lower alkane and catalytic cracking of higher alkane and higher olefin. The process increases the yield of product with high value and decreases the yield of product with low value significantly. At the same time, the power consumption is decreased as a whole since most reactants are converted in catalytic cracking at lower temperature.
