SO2 oxidation w/o a catalyst
|
|
|
I am interested in the rate at which SO2 oxidizes to SO3 in the absence
of a catalyst. It seems like this ought to be a well known and
researched reaction. I know that at lower temperatures (below ~600) SO3
is favored and at higher temperatures SO2 is favored. Specifically,
what happens if I put SO2 with an excess of O2 into a plug flow reactor
(no catalyst, no photons) what will the conversion be? So far
everything I have seen is either about a sulfuric acid plant or photo
catalyzed in the Earth's or Venus's atmosphere.
Can anyone point me in the right direction?
Thanks

At 600 degrees and with an excess of oxygen, I don't think your pipes
will last very long...!!!
Not quite oxidation to SO3, but here's an interesting article
nonetheless...

Well U need to check basics of Gibbs energy for this reaction and then
u can find out the probable temperature range at which this reaction is
theoretically possible w/o catalyst.
However, it doesnt give u the rate of reaction but luckiest thing is
that u have suffciient data available on this reaction for the
parameters required to calculate the rate of reaction. |
