What kind of internals should be used in the hydrocracking reactor to reduce radial temperature differences and prevent excessive temperature rises?
A gas distributor with good performance is used, and the shape of the catalyst itself also has a significant impact.
Temporarily, the internal components of hydrocracking unit reactors in China seem to be similar, such as inlet diffusers, distribution plates, cold hydrogen tanks, redistribution plates, and so on. There are no special internal components that serve to reduce the radial temperature difference. “\"Rapid temperature rise\" is generally caused by process-related issues, such as the shutdown of the circulation pump or the failure to open emergency pressure relief valves; relying solely on the components inside the reactor is not sufficient to prevent this phenomenon.

What was said upstairs is correct – the internal components of hydrocracking reactors in China are more or less similar. We have worked on many such reactors, and the internal components used, whether for gasoline, diesel, residue, etherification, hydration, etc., include inlet diffusers, fouling barriers, distribution plates, catalyst support plates, cold hydrogen tanks, redistribution plates, and outlet collectors. The design takes into account the flow rates of oil and gas, hydrogen, water vapor, etc.; as long as these parameters are not changed arbitrarily, no significant temperature changes will occur
