Ga modification of the H +-β zeolite significantly enhanced cumene yield in the continuous fixed-bed reactor at 225°C, from 27% of the unmodified β-zeolite to 36% for the Ga-modified one. The life span of modified β-catalysts was studied in the fixed-bed reactor for the first eight hours of reaction.

Heterogeneous catalytic reactor - Wikipedia

Jun 09, 2019 · A circulating fluidized-bed (CFB) reactor is extremely the same as a bubbling fluidized-bed reactor. the main distinction is that the gas rate.If the gas rate of a bubbling fluidized bed will increase, at some Location the force exerted on the particle are enough to move it upwards, carrying it outside of the bed.

Fixed-Bed Reactors - Uni Stuttgart

Fixed-Bed Reactors 201 particular, fixed-bed reactors with a strongly exothermic reaction exhibit an, at times, surpris­ ing operational behavior which is dIscussed in more detail in Chapter 6. Within a production plant the reactor may justifiably be regarded as the central item of .


Jun 09, 2019 · The bubbling fluidized bed is doubtless the foremost standard reactor for quick shift. the most disadvantage with fluidized-bed reactors is that they require fairly little particles (2–3 mm) to reduce heat/mass transfer effects: this leads to costly needs for grinding lignocellulosic biomass.

Design of fixed bed catalytic reactors

fixed bed catalytic reactor. In order to accomplish these objectives it was necessary to obtain a general solution to the energy and mass transfer equations which would predict the point values of temperature and concentration as a func­ tion of radial and longitudinal position in the catalyst bed.

What is the difference between fixed bed and packed bed .

Dec 25, 2016 · A2A Forgive me if I am wrong, it has been a while since I touched reactor design. The key different between a fixed bed and packed bed reactor is the reaction location. In fixed bed reactor, the reaction is done on the surface of the pellet inside.
