Slot Waveguide Resonator Microwave Chemical Reactor Optimization Design

Ethylene and acetylene are the most important basic materials of chemical industry, with the scarcity of petroleum resources, using natural gas to generate ethylene and acetylene is becoming the research focus of world. Because making methane to C2 alkynes by traditional methods need high temperature and high energy, so which don't have industrialization prospect. And making methane to C2 alkynes by microwave chemistry methods have obvious advantages. But most of microwave chemistry experiments are carried out in rectangular waveguide or resonator made of rectangular waveguide. So microwave chemistry methods exist some defects, such as smaller of microwave reaction resonator and lower of C2 alkynes output. In order to solve these defects, we put forward microwave chemistry reactor made of groove waveguide resonator, and we do a lot of studies. Research contents of this paper include the following several:In the first side, I make theoretical derivation about dispersion characteristics of rectangular groove guide and circular groove guide by transverse resonant method in 2.45GHz, and obtain corresponding dispersion equation. Then we use MATLAB software to programming calculation, and obtain the cut-off characteristic and waveguide wavelength of rectangular groove guide and circular groove guide. By comparison with other paper, it proves the validity and efficiency of our method. Another, we use MATLAB software to optimize the rectangular groove guide reactor and the circular groove guide reactor, and obtain the stable value of normalized cut-off wavelength in optimal structure and size.According to theoretical analysis, we use HFSS software to further optimize microwave chemistry reactor made of rectangular groove guide reactor and microwave chemistry reactor made of circular groove guide reactor in 2.45GHz and 1W. From the simulation solution, we prove out the correctness of solving method, and get the optimal structure and size of microwave chemistry reactor. Under the optimal structure and size, the maximum field strength of microwave chemistry reactor made of rectangular groove guide reactor reaches 104V/m, and exist larger region. But the maximum field strength of microwave chemistry reactor made of circular groove guide reactor only has 2000V/m. So microwave chemistry reactor made of rectangular groove guide reactor is more suitable to make methane to C2 alkynes. Under the effect of high power and actuator, it can form microwave discharge, and make methane to C2 alkynes in microwave chemistry reactor made of rectangular groove guide reactor under atmospheric.
