摘要：
Tungsten oxide/zirconia (W/Z)-based catalysts were prepared and their performances were tested for the oxidative coupling of methane (OCM) reaction. Two types of new catalysts were found; One is prepared by impregnation of both Eu or Ce and Li2CO3 over W/Z, and the other is by impregnation of both Ce or Mn and NaCl. The former catalysts showed long lifetime over 100h, but modest C2 yield(ca.18%), while the latter showed excellent C2 yield over 30%, but rather short lifetime (ca.30h).
