Ceramic balls diameter

[shvet]

Dear forummembers, please advise a rule of thumb or comment the design or a reactor below.

We have a reactor where catalyst bed is supported by ceramic balls bed:
- catalyst shape is cilinders OD=6mm, H=4mm
- support bed are 2 layers of ceramic balls OD=6&19mm

What do you think? Are 6mm balls edequate for supporting 6x4mm catalyst or should smaller/bigger balls be used? Do you know a rule of thumb or a common practice concerning this parameter?

ask the catalyst company, it must be in the technical proposal.

3/4 in should be a good choice, but the catalyst manufacturer shall give you the advice

I'd also consult GPSA Databook and vendor recommendations.
Good luck

The licensor of the unit has the standard for the catalist feeding.
