What are the reasons for fluctuations in catalytic reaction temperature?
1: Regenerator temperature fluctuations 2: Fluctuations in the regeneration slide valve 3: Water content in the feed oil 4: Reduced processing volume
1. Change in catalyst circulation rate 2. Change in reaction feed rate 3. Change in feed temperature 4. Change in regenerator bed temperature 5. Change in steam supply to the lift column 6. Change in feed composition 7. Water content in crude oil 8. Change in amount of reactant used to terminate the reaction 9. Change in differential pressure between the two vessels 10. Inefficient regulation of the regeneration valve or automatic operation due to low pressure 11. Change in steam supply for stripping in the settler

The answers on floors 3 and 4 are quite comprehensive; two additional points: 12. Catalyst regeneration efficiency； 13. Changes in heat absorption from inside and outside.

Problems with fluidization in the regeneration line, changes in the differential pressure between the two vessels, changes in the catalyst circulation rate, changes in the amount of reactant fed into the reactor, changes in the properties of the reactant feed, water content in the crude oil, changes in the amount of steam supplied to the lift pipe, fluctuations in the temperature of the regenerator, fluctuations in the amount of recycled slurry, changes in the differential pressure between the two vessels, changes in the temperature of the reactant feed, the effectiveness of catalyst regeneration, and changes in the heat absorbed from inside and outside the system.
