This research aims to study the comprehensive identification of the synthesis, characterisation and performance tests of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) and La0.7Sr0.3MnO3-δ (LSM) granule-form catalysts with a CeO2 and NiO addition for the POM reaction. The LSCF and LSM powder were firstly prepared using the solid-state reaction method. The granules were firstly prepared in a form of pellet, then crushed and sieved into a size of ± 1 mm. The performance study begins with a pre-treated process, by flowing 5 % O2 gas (30 mL∙min-1) in the fixed-bed reactor at 600 °C. The product was analysed using Agilent HP 6890 gas chromatography equipped with an Agilent HP 19095P-Q04 column and a FID detector. The results showed that the LSCF achieved 50.03 % methane conversion which is lower than the LSM performance of 56.41 %. The CeO2 addition in both the LSCF and LSM revealed an increasing performance by increasing the reaction time. NiO addition resulted in a slower increase in the reaction time, which can be caused by the rate of carbon deposition formation. Based on the obtained results, the bifunctional catalyst has the potential to be developed into another module with a larger effective surface area, such as a multiple-thin layer membrane or hollow fibre membrane.
