Abstract
Ni–Na<sub>2</sub>CO<sub>3</sub> DFMs are synthesized and calcined at different temperatures. Low quantities of promoters (La, Co, Fe, Ca, Ce, Ru, Pd and Mn) were added to the DFMs. 10% Ni–10% Na<sub>2</sub>CO<sub>3</sub>(1%Ru)/Al<sub>2</sub>O<sub>3</sub> presents the highest CH<sub>4</sub> production with high selectivity.
