Methane Chlorination with Chlorine Molecules using Zeolite Catalysts: Effects of Si/Al Ratios and Framework Types |
초록 |
Methane (CH4) chlorination with chlorine molecule (Cl2) can produce various chlorinated products via C-H bond activation in CH4. This reaction can occur spontaneously with irradiation of UV light even in the absence of a catalyst, which follows a free radical-mediated chain reaction mechanism. Therefore, the various products can be formed with a statistical thermodynamic distribution. In this work, CH4 chlorination is controlled by using HY and MFI zeolites with various Si/Al ratios under various reaction conditions in order to break the thermodynamic product distribution and thereby produce a desired mono-chlorinated product (i.e., CH3Cl). The results demonstrated that the framework type of zeolite and its Si/Al ratio could control the CH4 conversion, CH3Cl selectivity, and hence CH3Cl yield under various reaction conditions. In particular, systematic correlations between the catalyst properties and CH3Cl yield were constructed. All the zeolite catalysts suffered from framework dealumination by HCl produced during the reaction. The details of CH4 chlorination and the results are going to be addressed in this poster. |
