| titleOfInvention | Startup method of vulcanized catalyst |
| abstract | The invention discloses a startup method of a vulcanized catalyst, which comprises the following steps: filling the vulcanization type hydrogenation catalyst composition into a reactor, carrying out nitrogen gas tightness, gradually introducing hydrogen after the nitrogen gas tightness is qualified, carrying out hydrogen low-pressure gas tightness, and heating and boosting to carry out high-pressure gas tightness after the low-pressure gas tightness is qualified; and after the high-pressure airtight condition is qualified, adjusting the pressure to the reaction pressure until vulcanization is completed, finally adjusting the temperature to the reaction temperature, and starting hydrogenation reaction on the raw oil. The start-up method can ensure the vulcanization quality of the catalyst, solve the problem of air tightness of the device, and has no pollution to the environment, economy and environmental protection. |
