Description
Summary:The study has focused on the development of bifunctional catalytic materials for the direct DME synthesis from CO.sub.2/H.sub.2. The industrial Cu/ZnO/Al.sub.2O.sub.3 is used as the copper based catalyst for the first step of the methanol synthesis from CO.sub.2/H.sub.2. It will be combined with hollow nano-ZSM-5 zeolites with mesoporous shell as the acid catalyst of the second step the methanol dehydration to DME. The bifunctional materials will be tested in the direct DME synthesis from CO.sub.2/H.sub.2 under the following conditions: T = 225 °C, p = 30 bar, H.sub.2/CO.sub.2 = 3. Under our reaction conditions, CO was not observed, only the DME majority product (77.5%) and CH.sub.3OH (22.5%) were obtained.
