Physical mixtures of AgCeO₂ and ZrO₂/SiO₂ were employed in the ethanol conversion to propene in the presence of water through the acetone route. The oxides were characterized by XRD, N₂ physical adsorption, isopropanol dehydration/ dehydrogenation and ethanol to acetone MPV model reactions. The mixtures were tested under different WHSVs and temperatures. This study presents new perspectives for the propene synthesis from ethanol. MPV reduction and dehydration are both important for the overall reaction. Understanding how to balance these reactions is an important step towards the synthesis of new catalysts able to produce propene from ethanol, with high selectivity to propene.

将AgCeO ₂和ZrO ₂ / SiO _2的物理混合物用于在丙酮通过水的存在下将乙醇转化为丙烯。通过XRD，N ₂物理吸附，异丙醇脱水/脱氢以及乙醇制丙酮MPV模型反应对氧化物进行了表征。在不同的WHSV和温度下测试混合物。这项研究提出了从乙醇合成丙烯的新观点。MPV的减少和脱水对于整个反应都很重要。理解如何平衡这些反应是合成能够由乙醇生产丙烯且对丙烯具有高选择性的新型催化剂的重要一步。
