| titleOfInvention | FCC gasoline desulfurization and hydrogenation modification method |
| abstract | The invention relates to a method for improving the hydro-upgrading performance of gasoline. Catalyst HDS activity evaluation FCC gasoline was used as feedstock. The sulfiding agent used in the HDS evaluation was a cyclohexane solution containing 2 m% CS 2. The catalyst HDS activity evaluation procedure was as follows: firstly, presulfurizing is carried out, the loading of the catalyst is 2g, the pressure is regulated to 2.5MPa, and the gas flow is 25 ml.min ‑1 And opening a load switch of the reactor, adjusting a temperature controller of the reactor to heat up, and opening a prevulcanization valve on a panel of the device to start prevulcanization when a temperature measurement display of the reactor displays 150 ℃. H 2 The volume ratio of Oil to water is 300, and the WHSV is 1.82h ‑1 Prevulcanization is carried out for 4h, and then raw oil is switched to carry out reaction. The HDS evaluation conditions were: temperature 260 ℃ and H 2 Volume ratio of Oil to Oil of 200, pressure of 2.0MPa and WHSV of 2.0h ‑1 The multi-stage pore molecular sieve composite catalyst is used for the FCC gasoline hydrogenation modification process to show higher hydrodesulfurization rate, maintain the octane number of the FCC gasoline to the maximum extent and show excellent hydrogenation modification performance. |
