Oxidative coupling of methane in the redox cyclic mode over the catalysts on the basis of CeO sub(2) and La sub(2)O sub(3)

Oxidative coupling of methane in the redox cyclic mode over the catalysts on the basis of CeO sub(2) and La sub(2)O sub(3)

The 1% CeO sub(2), 9% La sub(2)O sub(3)/SiO sub(2) and 2% CeO sub(2), 8% La sub(2)O sub(3)/SiO sub(2) catalysts show reliable efficiency in the OCM reaction, as well as stable work in the redox cyclic mode. Selectivity to C sub(2) products remarkably increases if preliminary reduction of the catalys...

Zusammenfassung:The 1% CeO sub(2), 9% La sub(2)O sub(3)/SiO sub(2) and 2% CeO sub(2), 8% La sub(2)O sub(3)/SiO sub(2) catalysts show reliable efficiency in the OCM reaction, as well as stable work in the redox cyclic mode. Selectivity to C sub(2) products remarkably increases if preliminary reduction of the catalyst by a small amount of hydrogen is used.
