Abstract

The kinetics of the reduction of PbO supported on Al2O3by methane is studied in the temperature range 760–927°C. The reaction order with respect to methane is equal to unity and the apparent activation energy is ∼40 kcal/mol. When the extent of PbO reduction is 0.5–0.6, the selectivity of methane conversion changes drastically: only CO2is formed at lower extents of reduction, whereas CO is the main product at higher extents.
