PURPOSE: To convert methane into 2C components such as ethane, ethylene, etc., in high conversion ratio and in high selectivity by bringing methane into contact with a catalyst prepared from a titanium oxide, lithium salt, phosphate and an oxide of element of group III in the presence of oxygen.
CONSTITUTION: Methane is brought into contact with a catalyst shown by the formula (M is element of group III; 1<l<3; 0<m<2; 0<n<2) in the presence of oxygen at 700-850°C and converted into 2C components such as ethane, ethylene, etc. The catalyst is obtained by blending a titanium oxide (e.g. TiO2, Ti2O3 or TiO) with a Li salt (e.g. Li2CO3, Li2O, LiOH or LiHCO3), a phosphate [e.g. (NH4)2HPO4 or (NH4)H2PO4] and an oxide of element of group III (e.g. Al2O3 or Ga2O3) and subjecting to solid-phase reaction at 900-1,200°C. The molar ratio of methane/oxygen is preferably 1-20.
