Abstract

The paper presents the results obtained in studying glycerol hydrogenolysis into 1-propanol and 2-propanol over bifunctional Ni/WO-TiO and Ni/WO-ZrO catalysts in the flow system. Due to the optimal combination of acidic and hydrogenation properties of the heterogeneous catalysts, they exhibit higher performance in glycerol conversion into C alcohols, although the process is carried out in rather mild conditions. At the reaction temperature of 250 °C and hydrogen pressure of 3 MPa, the total yield of 1-propanol and 2-propanol reaches 95%, and the glycerol conversion is close to 100%.

摘要

本文介绍了在流动系统中使用双功能 Ni/WO-TiO 和 Ni/WO-ZrO 催化剂研究甘油氢解为 1-丙醇和 2-丙醇的结果。由于多相催化剂的酸性和加氢性能的最佳组合，它们在甘油转化为 C 醇的过程中表现出更高的性能，尽管反应条件相当温和。在反应温度为 250°C 和氢气压力为 3 MPa 的条件下，1-丙醇和 2-丙醇的总收率达到 95%，而甘油转化率接近 100%。
