Size of catalyst
Size of catalyst
(OP)
Does the size of the reactor (catalyst weight) needs to be changed if we want to change the feed.
Initially only fresh reactants were charged but now since the products forms not only the desired product but also undesired products as well, so I want to recycle back the undesired products but the feed rate of fresh reactants is same as before. Actually its amination of Methanol. It produces MMA DMA and TMA in the presence of zeolite catalyst. I want DMA not MMA and TMA so they are recycled back.
Please advice.

RE: Size of catalyst
Between your company and the catalyst vendor, you should be able to quantify an answer.
RE: Size of catalyst
But since I am recycling now so would it make any difference? or same size of catalyst can be used?

RE: Size of catalyst
An alternative solution would be a separate reactor for the undesired byproducts only i.e. instead of blending them back into the feed.
I think you won't find the optimum solution by thinking in qualitative terms only. Get a good simulation model of your unit and see what happens in quantative terms in the different scenarios.
