In this paper natural basalt was used as a catalyst for pyrolysis of methane. The composition, structure and surface species of the catalyst were investigated by XRF, XRD, SEM and XPS techniques. Catalytic properties of basalt catalyst were studied for methane catalytic pyrolysis under different reaction temperature and space velocity in a fixed bed reactor. At the condition of GHSV 4 L?h-1 and 1225 K, the conversion of methane was 7.66 % and the selectivity of C2 was 33.64 %. When the temperature reach up to 1325 K, the conversion of methane increased to 17.13 % while the selectivity of C2 reduced to 27.21 %. Under the same temperature, the selectivity of ethane increased with the increasing gas space velocity, however, the selectivity of acetylene reduced. The reactive activity of basalt decreased because the aromatic type of coke formed at the external surface.
