Methane was directly converted to butene liquid fuel by microwave-induced non-oxidative catalytic dehydrogenation under 0.1-0.2 MPa. The results show that, under microwave heating in a two-stage fixed-bed reactor, in which nickel powder and NiO -MoO/SiO are used as the catalyst, the methane-hydrogen mixture is used as the raw material, with no acetylene detected. The methane conversion is more than 73.2%, and the selectivity of methane to butene is 99.0%. Increasing the hydrogen/methane feed volume ratio increases methane conversion and selectivity. Gas chromatography/electron impact ionization/mass spectrometry chromatographic analysis showed that the liquid fuel produced by methane dehydrogenation oligomerization contained 89.44% of butene, and the rest was acetic acid, ethanol, butenol and butyric acid, and the content was 1.0-3.0 wt%.
在0.1 - 0.2MPa压力下，通过微波诱导非氧化催化脱氢将甲烷直接转化为丁烯液体燃料。结果表明，在以镍粉和NiO - MoO/SiO为催化剂的两段固定床反应器中进行微波加热时，以甲烷 - 氢气混合物为原料，未检测到乙炔。甲烷转化率超过73.2%，甲烷制丁烯的选择性为99.0%。提高氢气/甲烷进料体积比可提高甲烷转化率和选择性。气相色谱/电子轰击电离/质谱色谱分析表明，甲烷脱氢齐聚反应生成的液体燃料中丁烯含量为89.44%，其余为乙酸、乙醇、丁烯醇和丁酸，含量为1.0 - 3.0wt%。
