Abstract A process for modifying catalytically cracked gasoline in contact with solid acid catalyst containing five-membered-ring mesopore zeolite in lifting-tube reactor, reacting at 300-600 deg.C and 130-450 Kpa for 1-6 seconds, and with a rate of 3-16:1 wt. of catalyst and catalytic cracked gasoline, and with a rate of 0.01-0.3:1 wt. of steam and catalytic cracked gasoline, separating resultant product, stripping the catalyst to be regenerated, regenerating and returning it back to reactor for cyclic use. Its advantages are low content of olefine, diene and nitrogen in gasoline and high output of low-carbon olefine as by-product.
