CO2 assisted oxidative dehydrogenation (ODH) propane to propylene overfluidizable mesoporous VOx/La2O3-gAl2O3 catalysts has been investigated. The mixed oxide of La2O3 and gAl2O3 were synthesized bythe co-precipitation technique and VOx was deposited on the supports by an incipient wetnessimpregnation approach. The prepared catalysts were characterized by various physicochemicalcharacterizations to establish the desired properties of the catalysts. The H2-TPR indicated the supportedVOx reduced in a single stage, indicating the formation of a homogeneous specie. Both the acidity andsurface area of the catalysts decreased with increase of La content, as confirmed by the NH3-TPD and BETanalysis, respectively. The CO2 assisted ODH of propane experiments were developed in afluidized CRECRiser Simulator at 520–600 C. The introduction of CO2 significantly enhanced both the propaneconversion and propylene selectivity. Among the studied catalysts, VOx/g-Al2O3 catalyst showed highestpropylene yields (42.7%) at 550 C.
