【Q&A Question 100】July 29, 2016: How to adjust the cat reaction? The answer key will be available after responding; scoring is based on answering the key points. Adjustable: 1. Raw material temperature ； 2. Pressure exchanger bypass opening ； 3. Reactor outlet temperature ； 4. By adjusting the amount of quench hydrogen.
What does this question mean? Does the catalyst need to be adjusted? Means of adjusting the reaction: replacing the highly active catalyst, hydrogen-to-oil ratio, space velocity, hydrogen partial pressure, reaction temperature, etc
The answer to your question seems to be methods for controlling the temperature of the reaction bed in order to prevent catalyst coking? I still don’t understand what you mean by your question even after looking at the answer.
1. Adjust the hydrogen-to-oil ratio and modify the pressure in the reaction system； Adjust the circulation volume of the cycle compressor ； Adjust the feed amount ； 2. Adjust the reactor feed temperature ； 3. Adjust the raw material composition
In the reaction units of hydrogenation plants, the catalysts are generally not changed; fixed-bed catalysts are used. The reactor pressure is controlled by adjusting the high-pressure regulator, while the temperature is controlled by adjusting the reactor.
Adjustable: 1. Raw material temperature； 2. Pressure exchanger bypass opening ； 3. Reactor outlet temperature ； 4. By adjusting the amount of quench hydrogen.
It’s fine if you don’t understand; the original poster can make adjustments: 1. Raw material temperature； 2. Pressure exchanger bypass opening ； 3. Reactor outlet temperature ； 4. By adjusting the amount of quench hydrogen.
