The direct non-oxidative methane aromatization over commercially available gallium nitride powder has been investigated for the first time in a fixed bed reactor under continuous operation. Gallium nitride catalyst is highly active. High reaction temperatures (650–710 °C) are needed to initiate benzene formation due to the small surface area (8 m² g^− 1) of the gallium nitride material, thermodynamic constraints and the low residence time (1–4 s). Besides benzene and toluene, C₂ species and coke were formed.

连续流反应器中氮化镓催化剂上的直接非氧化甲烷芳构化

在固定床反应器中连续运行下，首次研究了市售氮化镓粉末上的直接非氧化甲烷芳构化。氮化镓催化剂是高活性的。由于氮化镓材料的表面积小（8 m ²  g ^-1），热力学约束和滞留时间短（1-4 s），因此需要高的反应温度（650-710°C）才能引发苯的形成。除苯和甲苯外，还形成了C ₂物种和焦炭。
