Reducing Olefins Content of FCC Gasoline Using a NANO-HZSM-5 Catalyst

摘要

The study of reducing olefins properties on nano-HZSM-5 catalyst was investigated with a continuous fixed reactor using fraction of fluid catalytic cracking gasoline (75N120°C).The experimental results showed that nano-HZSM-5 catalyst has the best reducing olefins properties under the optimal conditions:temperature 430°C,pressure 0.3 MPa,and liquid hourly space velocity 1 h~(-1),and the content of olefins in the feed stock decreased to 12.11% and dropped 31 percentage points.The yield of liquid product,the content of aromatics,and the content of isoalkane in liquid product are up to 84.98%,39.58%,and 35.23% respectively.
