The investigation of methane oxidative coupling on BaF2-LaOF catalyst

The OCM reaction was studied on BaF2-LaOF catalyst and the results show that CH4 can be effectively activated and selectively converted to C-2(+). Under the reaction conditions of GRSV=15000h(-1) and reaction temperature 1044K, the high C-2(+) yield of 20.66% with CH4 conversion of 33.08% and C-2(+) selectivity of 62.47% was obtained at CH4:O-2=3:1, and the high C-2(4) selectivity of 84.55% with CH4 conversion of 16.54% was obtained at CH4:O-2=9:1. XRD results suggest that tetragonal LaOF is the active phase in BaF2-LaOF catalyst.
