The V2O5/TiO2 catalyst was prepared using a sol-gel synthesis method. Characterization through XRD, BET surface area, and SEM/EDX analysis was carried out on the catalyst. The catalyst performance was tested in a lab-scale catalytic oxidation system with and without ozone to optimize the reaction parameters of residence time, ozone / methanol ratio, and reaction temperature. The destruction of methanol and the formation of major byproduct, Methyl Formate (MF), was analyzed. In addition, six other previously characterized V<sub>2</sub>O<sub>5</sub>/TiO<sub>2</sub> catalysts of various vanadia loadings synthesized by the wet incipient method were tested generally for comparison both in the presence of ozone and without ozone. This investigation shows that vanadia / titania catalysts used in combination with ozone are promising in the low temperature oxidation of methanol. The combination was found to successfully oxidize over 98 percent of initial methanol at a temperature of 150°C. Variation in the ozone / methanol ratio, residence time, and temperature in the preferred range of 100 to 150°C demonstrated that the selectivity to MF and CO<sub>2</sub> can be significantly impacted by process variables. Comparison of the varied vanadia loadings in the catalysts resulted in a V/Ti ratio = 0.05 as the most active without ozone, but V/Ti = 0.01-0.05 act approximately the same in the presence of ozone. 2005-04-25 English text Miami University Honors Theses / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=muhonors1114188719 http://rave.ohiolink.edu/etdc/view?acc_num=muhonors1114188719 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
