Vanadium and titanium oxide species were successfully deposited on a mesoporous SBA-15 support by the Molecular Designed Dispersion (MDD) method. A combination of different techniques (XRD, N-2-soprtion, DRS, H-2-TPR and Raman) was used to verify the nature of the vanadia on the various mesoporous catalysts. The catalytic performance for the oxidative dehydrogenation of isobutane was investigated by steady-state experiments in a fixed bed micro multi-tubular reactor. Catalysis was focused on the selective production of olefins such as isobutene and propene. The catalytic results are presented in varying process conditions and are discussed in terms of V loading, V dispersion and Ti promotion.
