Embodiment 1
[0016] FCC gasoline with a sulfur content of 500-800μg / g is used as raw material, the feed flow rate is 15L / h, and the raw material is heated to 105-115°C to enter the membrane system. The effective membrane area of each stage of the two-stage membrane separation system is 1m 2 After being treated by the device, the sulfur content of the FCC gasoline can be reduced to 50-100 μg / g, and the octane number loss of the FCC gasoline after desulfurization is below 1%.
Embodiment 2
[0018] FCC gasoline with a sulfur content of 800-1100μg / g is used as raw material, the feed flow rate is 15L / h, and the raw material is heated to 105-115°C to enter the membrane system. The effective membrane area of each stage of the two-stage membrane separation system is 1m 2 After being treated by the device, the sulfur content of the FCC gasoline can be reduced to 150-400 μg / g, and the octane number loss of the FCC gasoline after desulfurization is 1-1.5%.
