Conversion of CH4 to value-added products has been interesting subjects for a long time. Among the capable material of being produced, CH3Cl, one of the major products of CH4 chlorination, can be used for starting material that can be converted to hydrocarbons. However, selective production of CH3Cl with less formation of undesirable chloromethane products is challenging since the reaction with Cl2 is always accompanied with radical-mediated non-selective chlorination pathway. Previous studies reported that solid acid catalysts can induce polarization of Cl2 molecule, and radical chlorination process can be shifted to ionic chlorination process. Shifting the reaction process predominantly to the ionic pathway increased the yield of CH3Cl and decreased the production of poly-chloromethanes. In our recent study using ion-exchange zeolites series, we found that the production of CH3Cl could be changed by the chemical properties of introduced metal ions. In this poster, we also used ion-exchanged zeolites which transition metal ions as the catalysts for selective production of CH3Cl. The resultant series of catalysts exhibited significantly different phenomenon on the CH3Cl production. |
