Abstract
The oxidative coupling of methane (OCM) was studied on BaF2/LaOF and good catalytic results were obtained. Under the conditions of GHSV = 15 000 h(-1) and a reaction temperature of 1043 K, a C-2 yield of 20.66% with a CH4 conversion of 33.08% and a C-2 selectivity of 62.47% was achieved at CH4:O-2 = 3:1, and high C-2 selectivities of 81.20% and 84.55% with a CH4 conversion of 19.53% and 16.54% were obtained at CH4:O-2 ratios of 6:1 and 9:1, respectively. X-ray diffraction results showed that only tetragonal LaOF existed in the BaF2/LaOF catalysts with BaF2 content below 18 mol-%, but a contracted BaF2 phase was also observed at higher BaF2 content (above 18 mol-%).
