| Outline of Final Research Achievements |
Innovating synthesis techniques for zeolites is of high importance considering their industrial values in chemical and petrochemical processes. This project focused on developing an emulsion-based, continuous flow synthesis of zeolites. This synthesis strategy solved the precipitation issue caused by sharp viscosity increase and thus facilitated the continuous flow synthesis of zeolites. This research designed and fabricated a continuous-flow system to fulfill this objective and led to the emulsion-based, continuous flow synthesis of several zeolites including ERI, CHA and beta. This research studied the performances of the ERI zeolite in the NH3-SCR of NOx and the partial oxidation of methane to methanol. With an optimal Cu/Al ratio of 0.2, the ERI zeolite proved to be a high-performing NH3-SCR catalyst that matched the benchmark catalyst Cu-CHA. In addition, the ERI zeolite led to a methanol yield of 147 μmol/g-zeolite, proving it potential in this challenging reaction.
