Abstract	Researchers synthesized brønsted acidic ionic liquid [BPY]HSO4 to use as a catalyst in alkylation desulfurization of FCC gasoline. They examined the effects of the reaction temperature, time and mass ratio of ionic liquid to oil on the desulfurization efficiency and FCC gasoline quality. Results revealed that after reaction for 90 min under 65°C and an ionic liquid to oil mass ratio of 0.09, the sulfur content of FCC gasoline decreased from 580.0 to 6.4 μg/g, with a desulfurization rate of 98.90%, achieving the Chinese National Standard V for the sulfur content in motor gasoline.
