A preliminary study on the effect of temperature and carbon deposit on the reactivity of alumina during hydrocarbon oxidation

The oxidation of hydrocarbon with oxygen on alumina catalyst over a range of temperatures was studied by using a flow reactor system equipped with a locally fabricated gas chromatogaphy apparatus. A saturator was integrated into the set-up in order to convert the liquid hydrocarbon into vapor phase....
