MARCH 8, 2019

This research, published in the journal Separation and Purification Technology , shows that ozone can be used to remove not only SO x but also NO x from fossil fuel combustion exhaust streams. In our previous study, we found that MnO 2 can absorb not only SO 2 but also NO 2 simultaneously. Osaka et al.
