Addition of ambient temperature air to exhaust in SCR
« on: May 13, 2014, 11:55:50 PM »
Hi. I am trying to do some research on selective catayst reduction for the exhaust from electric power plants, particularly using ammonia injection and vanadium catalysts. I have the following kinetics( see picture)


I was thinking that low temps would be better for operation since Ea2>Ea1, and that higher ratio of NH3 to NO would be beneficial to increase NO conversion the but not in a very large amount as residual NH3 might leave in the outlet.

I was  curious though as to how the addition of air at ambent temp would affect my peak NO conversion. I thought that addition of air would increase values of O2 and cause the second undesired reaction to occur more frequently, but I am not sure.



If anyone could provide any insight into this I would greatly appreciate it.

Sorry about that. I guess it did not upload properly.
