Perovskite catalysts for the catalytic flameless combustion of methane [PDF]

Applied Catalysis B: Environmental, 2000
Abstract A new method was employed for the preparation of a set of lanthanum cobaltites of general formula La1−xMxCoO3+δ with M=Ce, Eu and x=0, 0.05, 0.1, 0.2. All the samples thus prepared were nanostructured, thermally very stable and characterised by highly crystalline perovskite-like structure and high surface area.

Combustion Mode and Reactivity of Methane Fuel in Hot O2/CO2/N2 and O2/H2O/N2 Coflows in a Nonpremixed Small‐Scale Tube Burner

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The reactivity of methane fuel was numerically studied to compare the effects of CO2 and H2O dilution of hot oxidizer atmospheres on combustion modes and flame characteristics. A nonpremixed small scale burner at 8.6 kW thermal load forming central fuel jet flame in coflow oxidizer atmosphere was employed.
