摘　　要：在常压低温下采用非平衡等离子体技术研究低碳烷烃无氧烯烃化反应.研究结果表明:甲烷在等离子体中的脱氢偶联反应的主要产物是碳二烃;乙烷在等离子体作用下主要脱氢产物是乙烯、乙炔;甲烷和乙烷混合气可以在等离子体系中得到活化,生成乙烯、乙炔,为甲烷和乙烷在无氧气氛下不经分离直接活化制烯烃提供实验依据.Under the condition of normal pressure and at low temperature, non-equilibrium plasma was used for conversion of light alkanes to alkenes without oxygen. Investigation results showed that in pure methane gas,methane was mainly converted to C2 hydrocarbons; in pure ethane gas, converted to C2H2 and C2H4. For the mixture gas of methane and ethane, the main products was C2 H2 and C2 H4 under the condition of plasma. This research suggested that the methane and ethane can be converted to alkenes directly without separation.
