Performance of Oxidative Coupling of Methane (OCM) reactor using the research benchmark Mn-Na₂WO₄/SiO₂ catalyst under various sets of operating conditions was experimentally investigated. In particular, the impacts of varying the operating parameters (630 combination-sets) namely; reactor set-temperature (in 6 levels in the range of 750–875 °C), feed flow-rate (in 5 levels in the range representing GHSV -Gas Hourly Space Velocity- of 9600-19200 cm³ g⁻¹ h⁻¹), methane-to-oxygen ratio (CH₄/O₂ in 7 levels in the range of 1.5–10), and inert gas dilution (in 3 levels at 0%, 25% and 50%) on the recorded trends of methane-conversion and selectivity and yield of the desired products (C₂: C₂H₄&C₂H₆) were systematically reviewed. The performed experimental analysis enabled determining the impact of each investigated parameter as well as their interactive impacts through a carefully designed set of experiments. The novel proposed contour graphs visualized how the temperature and methane-to-oxygen ratio for instance directly influence the contribution of the catalyst or indirectly affect the reactor performance in synergy with the variation of dilution and feed flow due to their thermal impacts via affecting the intensity of the gas-phase and catalytic reactions in reactor-scale. It was demonstrated that in wide ranges of variation of these operating parameters, the recorded OCM reactor performance for instance in terms of the observed selectivity represent the interactive impacts of the intrinsic characters of the catalyst and the reactor’s characteristics such as its dimension and thermal capacity. Therefore, these aspects should be carefully considered in design of experiments and in the interpretation of the experimental observations for the research purposes as well as in the design and operation of large-scale reactors.

实验研究了使用研究基准 Mn-Na ₂ WO ₄ /SiO ₂催化剂的甲烷氧化偶联 (OCM) 反应器在各种操作条件下的性能。特别是，改变操作参数（630 组组合）的影响是：反应器设定温度（在 750-875 °C 范围内的 6 个级别），进料流速（在代表 GHSV - 气时空速 - 9600-19200 cm ³ g ^-1 h ^-1的范围内的 5 个级别）), 甲烷-氧气比 (CH ₄ /O ₂在 1.5-10 范围内的 7 个级别）和惰性气体稀释（在 0%、25% 和 50% 的 3 个级别）记录的甲烷转化率和所需产物的选择性和收率趋势（C ₂： C ₂ H ₄ & C ₂ H ₆) 进行了系统审查。进行的实验分析能够通过精心设计的一组实验来确定每个研究参数的影响及其交互影响。新提出的等高线图形象化了温度和甲烷与氧气的比率如何直接影响催化剂的贡献或间接影响反应器性能与稀释和进料流量的变化协同作用，因为它们的热影响通过影响强度反应器规模的气相和催化反应。结果表明，在这些操作参数的广泛变化范围内，记录的 OCM 反应器性能，例如在观察到的选择性方面，代表了催化剂的内在特性和反应器的特性（例如其尺寸和热容量）的交互影响。因此，在实验设计和为研究目的解释实验观察以及在大型反应堆的设计和运行中，应仔细考虑这些方面。
