乙炔、乙烯是重要的有机合成原料,利用甲烷生产乙炔、乙烯一直受到人们的关注。近年来已有用激光裂解甲烷得到乙炔的报道,但激光器价格昂贵,消耗电能也较高。我们对微波激发甲烷裂解反应的静态体系进行了实验研究,用自制的反应系统与检测质谱仪联机,测得气相裂解反应主要产物为乙炔、乙烯,其中乙炔含量可达66％。通过对产物组成与气体初始压力、激发时间,微波功率关系的研究,找到最佳实验条件。本方
Acetylene, ethylene is an important organic synthesis raw materials, the use of methane to produce acetylene, ethylene has been the concern. In recent years, there have been reports of using acetylene to crack methane with laser, but lasers are expensive and consume a lot of energy. We conducted an experimental study on the static system of microwave-excited methane cracking reaction. Using the homemade reaction system and the detection mass spectrometer, we found that the main products of the gas phase cracking reaction are acetylene and ethylene, in which the acetylene content can reach 66%. Through the study of the relationship between the product composition and initial gas pressure, excitation time and microwave power, the best experimental conditions were found. This side
