Effect of ZrO2 on the Stability of Cu-ZnO-ZrO2/HZSM-5 Catalyst for Syngas Conversion to Dimethyl Ether
The stability of Cu-ZnO/HZSM-5 and Cu-ZnO-ZrO2/HZSM-5 catalysts for syngas conversion to dimethyl ether has been evaluated using a fixed-bed flow microreactor at 290 °C, 40 atm, 1500 h−1. ZrO2 addition showed a marked improvement in the stability of catalyst.
