What is the inlet temperature for the hydrocracking reactor?
Thread Content
Hydrocracking is operating normally (this is not the first time it is started up after presulfurization); at what temperature should feed be introduced into the reactor, and what temperature is appropriate for the reactor when problems or accidents occur?
This is also related to the composition of your raw materials and the form of the catalyst; generally, the oil is fed in at around 300°C, and a safe temperature range is between 320°C and 300°C.
In normal operation, feeding is typically carried out at a weighted average reactor temperature of 300°C; in the event of an accident and during evacuation, a temperature below 320°C is considered a relatively safe level.
Generally, the oil is fed in at around 300°C, and the safe temperature range is also between 320°C and 300°C; this depends mainly on the activity of the catalyst. Factors such as the catalyst’s performance, the amount of time it has been in use, and the composition of the feedstock also play a role. If the catalyst is highly active and the feedstock is light, then a lower temperature is sufficient. On the other hand, if the catalyst has been in use for a long time and its activity is low, and the feedstock is heavy, then a higher reaction temperature is required.
