| 摘 要： | 研究了在过渡金属Fe-Ni催化剂与微波等离子体协同作用下甲烷偶联制乙炔的反应.考察了催化剂组成、微波辐照时间和体系压力对反应的影响.在体系压力为4 053 Pa、微波辐照时间为5 s、当组成催化剂的m(Fe)/m(Ni)=5.67时获得了较高的甲烷转化率(97.3%)和乙炔收率(73.5%).并分析了可能的反应机理.与微波场中其他催化剂的协同作用相比,本实验使用的过渡金属Fe-Ni催化剂显示了一定的优越性.

| Abstract: | Under the condition of the synergism of microwave plasma and transition metal catalyst, methane being coupled up and converted into acetylene has been studied in this paper. The effect of catalyst composition, microwave irradiation time and system pressure on the reaction was investigated. In the optimal operation, i.e., m(Fe)/m(Ni)= 5.67, 4 053 Pa system pressure and 5 s microwave irradiation time, the conversion of methane is up to 97.3% and the yield of acetylene is 73.5%. A possible reaction mechanism is presented to explain the experimental results. The synergism of transition metal catalyst used in this experiment is in advance of other catalysts under the same microwave irradiation. |
