| STUDY | In related work carried out with chemical engineers at Delft University of Technology, in the Netherlands, Baņares investigated oxidative dehydrogenation of propane on vanadium oxide catalysts supported on alumina. Using Raman spectroscopy and GC in tandem, Baņares observed that under steady-state conditions, the catalyst remains in an oxidized state that's free of carbonaceous deposits. But in the absence of oxygen, propane reacts with the catalyst to form two types of cokelike deposits: a graphitic form and a more aliphatic form |
