- W4308751639 abstract "Abstract Since its discovery in 1982, oxidative coupling of methane (OCM) has been considered one of the most promising approaches for the on‐purpose synthesis of ethylene. The development of more selective catalysts is essential to improve process economics. In this work, undoped neodymium oxide as well as neodymium oxide doped with high (20%) and low (2.5%) levels of strontium were tested in a high‐throughput fashion covering a wide range of operating conditions. The catalysts were shown to be able to achieve greater than 18% C 2 + yield. Space velocity was shown to play a significant role in C 2 + selectivity. For a methane to oxygen feed ratio of 3.5, selectivity increased with increasing space velocity, reaching a maximum of 62% at a methane conversion of 30% at an optimal space velocity of ~250,000 ml/h/g. The difference in activity between the three samples was linked to the contribution of different oxygen centers." @default.
