Benzene hydrogenation catalyst lifetime
Thread Content
What is the optimal temperature for the pre-reaction and main reaction in benzene hydrogenation? With a system pressure of 2.4 Mpa, what effects do lower or higher temperatures have on the process or the equipment? I hope my colleagues can share their views so that I can learn from them.
To exceed the dew point of the liquid, gas enters the reactor
Reply to 2# costume: This requirement is pretty easy to meet, I guess
Reply to 1# ygd111@163.com regarding the use of catalysts: 1. They are sensitive to high temperatures. 2. They are sensitive to liquids. 3. They are sensitive to coking substances. A lower reaction temperature is beneficial for chemical reactions; however, as operation time increases, coking substances inevitably accumulate on the surface of the catalyst, reducing its activity. If product quality starts to fluctuate at this point, then consideration can be given to raising the temperature. (Do not increase the temperature unless it is absolutely necessary.)
The temperature in the pre-reactor was initially controlled at 190 degrees; as time passed, the efficiency of the catalyst decreased, so the temperature had to be increased
What model of benzene hydrogenation catalyst is used, and which company manufactures it? Can methanol be produced from coke oven gas?
W216 crude benzene hydrogenation catalyst, from a company in Wuhan. This product is itself used for the hydrogenation of coked benzene.
