Abstract
This paper presents the results of lean methane oxidation in a two-chamber preheat catalytic reactor. A preheat catalytic reactor was built, and the effects of the space velocity (3800 hâ1 to 8100 hâ1), the inlet methane concentration (0.6 vol.% to 0.8 vol.%) and the inlet temperature of catalytic oxidation bed (420 °C-540 °C) were experimentally investigated. The results showed that when the space velocity is low, the methane conversion rate maintains a high value. But when the space velocity is higher than 7100 hâ1, the methane conversion rate decreases dramatically. With the increases of the inlet methane concentration and the inlet temperature, the overall temperature of the oxidation bed increases rapidly, the temperature increment of the first catalytic ceramic layer increases, the methane conversion rate increases.
