The catalyst supports were studied for the reaction C3H8 → 2CH4 + C (reaction 1). Neutral SiO2 and α-Al2O3 were found suitable while the acidic SiO2-Al2O3 support significantly reduced the activity of Ni catalyst. The catalyst was diluted by various materials to avoid its blocking up by carbon deposition. Some diluting materials affected the conversion. α-Alumina and basic MgO accelerated the reaction which may be due to the interaction between nickel and diluting materials through direct contact. Over Ni/SiO2, the reaction 1 showed 90% selectivity, so that the produced synthetic natural gas always contained H2 formed in the reaction C3H8 → 3C + 4H2.
