The direct conversion of methane or natural gas into useful hydrocarbon and oxygenated products has been the subject of extensive research during the past decade.
Partial oxidation of methane to formaldehyde was studied in a fixed-bed continuous flow reactor at the temperature range of 473-973 K using perovskite catalyst. La was taken as a basic material in A site. Ni, Co and Fe have been studied to test the catalytic activity and HCHO selectivity in partial oxidation of methane. Then La in A site was replaced by Ce and Co to study the activity change. TPR and XRD analysis were compared in view of the catalytic activity.
The order of activity was observed in the flollowing order: LaNiO_3 > LaCoO_3 > LaFeO_3. The highest HCHO selectivity was 16.4% on reduced LaNi_0.8Co_0.2NiO_3 at 450℃.
