This design has the following advantages:

1. Minimize the catalyst bed pressure drop

2. The reaction materials including ethylbenzene, water and air are fully mixed in the reactor, and the process meets the requirements of reaction kinetics

3. There is no coking phenomenon in the reactor to ensure the normal and stable operation of the production in a long period of time

4. The styrene yield is high, the selectivity is good, and the production index is in the forefront of the country

Schematic diagram of reactor system

After the reactor stress analysis, to ensure the normal use of the reactor for many years at high temperature (the reaction temperature exceeds 600 degrees), to ensure safety and stable production.
