Let's say I want to scale-up a reaction rom lab scale to pilot scale, there are defined parameters (Re, P/V etc) to get the RPM and power. Now my doubt is, How do I choose type of agitator, and how should I compare between different type of agitator?

Try contacting Elutia.  They make a TEA (Thermal Energy Analyzer) instrument. We used it to test for n- nitrosamines.  It first came out under Thermo, but I think Ellutia bought it from them.  The idea of the analyzer was to take the substances routed from a GC, pyrolyze them as they came out, then they were run through a could trap ( ours used EtOH and dry ice) and the left over gas went to the instrument.  The Instrument took the gasses (NOx) and reacted it with O3( O2 came in and was exposed to an electric arc to make ozone).  This chemoluminesced to produce red light which was measured.  There were other steps, but you get the.idea.  They might be able to help you.

I can't change pressure or composition. I have only physical means.
I can play with the container where the gas is in. Modify its material.

Hello
This is quite basic but I'm not an expert in chemistry...
2NO +O2 -> 2NO2
I need to slow down this reaction as much as possible, but the concentration of NO and O2 is fixed, and so is temperature and pressure. I can't add other chemicals...
Is there anything else that can be done e.g. applying electric voltage, magnetic fields, use the force...?
Thanks!
