Ethylbenzene alkylation and dealkylation reactions in the styrene plant
Thread Content
Our company is planning to set up a styrene production facility, and we are currently in the planning stage. I would like to ask everyone about the temperatures involved in the dehydrogenation reaction and the hydrogenation reaction. Higher reaction temperatures can enhance the activity of catalysts. Why is there a difference of over 100 degrees between the temperature of the hydrogenation reaction and the temperature of the dehydrogenation reaction (the outlet temperature)? Is it because the feed components of the two reactors are different, or is there some other reason? Solve
A higher reaction temperature can increase the yield of the reaction, but it reduces selectivity, shortens the catalyst’s lifespan, and increases energy consumption. It is necessary to choose the most appropriate reaction temperature based on factors such as the catalyst’s activity and other process conditions. Sometimes, to avoid unplanned shutdowns, production continues at high temperatures and with high energy consumption for a period of time. I’m not sure if this answer will satisfy your question
