Kinetic modeling of isobutane dehydrogenation over Ga2O3/Al2O3 catalyst

Kinetic modeling was done for isobutane dehydrogenation using an alumina supported gallia catalyst in a fixed bed reactor at atmosphere pressure, 520–580 °C and a short residence time (ca. 0.06–0.3 s). A complex reaction network was taken into account considering formation of not only isobutane, but also a range of other hydrocarbons in various side reactions. Parameter investigation revealed an adequate description of the experimental data. The apparent activation energy of isobutane dehydrogenation was estimated to be 195 kJ/mol.
