Research Of The Methane Coupling Parameter In Microwave Plasma

Microwave chemistry is a new knowledge that applies microwave technology to chemistry. In contrast to conventional chemical method, the microwave chemistry can accelerate the velocity of the reaction, activate some chemical reactions. It is also clean, without pollution technology and economical. Even when it appears is comparatively late, both microwave and chemistry field pay high attention to this new technology. In recent years, Microwave chemistry has been utilized in a lot of field of both industry and agriculture. Our country has taken emphasis on Microwave chemistry and many applications have been used in all fields.Based on Methane coupling up Ethane in Microwave plasma, we must make clear the importance of all parameter in chemical reaction system, so can control the reaction easily. This paper mainly studies how to measure reaction parameters working in the rectangle guide microwave chemical reactor. The key content is been divided into three aspects: how to measure Microwave plasma interspace temperature, the gas pressure in the vacuum, and hydrogenation methane coupling.Firstly, we introduce the plasma characters, applications and how to judge if it is plasma or not. The key is how to measure the electron temperature of Plasma. Then, based on the knowledge of Plasma, we particularly study how to measure the interspace of Plasma. We mend the thermocouple system to study the interspace temperature distribution of Plasma.In Microwave plasma, the gas pressure and hydrogen can heavy influence the result of Methane coupling. So we must study how to measure the parameter accurately. In this paper, there are the influence discussion of the hydrogen and experiment.The work of this paper accelerates the research of changing methane into ethene and increases the knowledge of the chemical reaction.
