Maximum temperature of diesel and gasoline hydrogenation reactor
Thread Content
What should be the maximum temperature of the reactor in a diesel and gasoline hydrogenation unit? . The current maximum temperature in the reactor is 372 degrees. Is it high? ? ?
The operating conditions are different, so the temperature may vary. It’s best to check the reactor’s design documents as well as the catalyst’s instruction manual.
Reply to 2# xjksh: The relevant information can no longer be found; we have been using the catalyst here for 8 years. It’s reaching its end

The values above are for reference only. Regardless of the differences in catalysts and reactor design conditions, it must be found if it exists. The catalyst has been in use for 8 years – it has operated for a long period of time. Let’s write a summary and share our experiences: lol
It’s Shandong Haida’s catalyst; in its later stages it can only increase the reaction temperature rise

Looking at the maximum operating temperature of your reactor, it is generally 390 degrees
Around 250~330+-2 degrees, I guess
It is best not to exceed 400°C, otherwise the cracking reaction intensifies, causing coking of the catalyst and reducing oil yield.
In this temperature range, there are generally no strict requirements for the catalyst. The maximum reaction temperature depends mainly on the design of the facility, specifically the material used for the reactor; older hydrogenation reactors can operate at around 427°C, while those newly built typically operate at around 450°C. 372℃ has no significant impact on the device; whether it is appropriate depends mainly on whether the product quality or its distribution can meet the actual usage requirements.
