Preparation of core-shell catalysts for one-step synthesis of dimethyl ether from syngas

  • 摘要: 以生物质(葡萄糖、蔗糖、淀粉)为模板剂,通过水热合成法制备具有核壳结构的CuO-ZnO-Al2O3@Al2O3复合催化剂,该催化剂以甲醇合成催化剂CuO-ZnO-Al2O3为核,甲醇脱水催化剂Al2O3为壳.SEM-EDS对催化剂核壳结构的表征发现,通过改变水热合成温度和合成时间可以调变催化剂中Al2O3壳层的厚度.将该复合催化剂用于合成气直接制备二甲醚的反应,在空速1 500 mL/(h·gcat)、温度260 ℃、压力5.0 MPa的条件下,CO转化率和二甲醚选择性分别达到35.2%和61.1%.
