Besides the work associated with combustion, part of my research work focused on the optimization of pollution abatement systems, in particular for the following activities: :

  • development of new catalytic reactors for natural gas vehicles. These devices have been developed for the mitigation of nitrogen oxide releases in exhaust gas using methane as a reducing agent. This work was conducted in collaboration with IST Lisbon and GDF-Suez during the thesis of A. Nobre Mendes * (defended in 2015) and has been the subject of a patent B1 and an article in Applied Catalysis A P1.
  • Analysis of catalyst aging processes and poisoning by alkali metals (sodium and potassium in the present case) from exhaust gases emitted by vehicles running on bio-diesel (Y. Xie thesis ** ) [P2, P3].
