摘要

摘要本文研究了采用不同方法（溶胶-凝胶法、熔融法、共沉淀法）合成的高负载含铜催化剂在氢气压力为 5.0 兆帕、温度为 100°C 的间歇反应器中进行糠醛加氢转化的情况。通过物理化学方法确定了催化剂的还原温度和相组成。结果表明，在所研究的工艺中，共沉淀铜氧化铝催化剂的活性最高，在 100-130°C 的温度下，其生产糠醇的选择性为 100%；此外，在该催化剂存在的情况下，在 200°C 的温度下，可合成 2-甲基呋喃，产率为 65%。已测定了在选定温度下还原的催化剂和反应后催化剂的相组成。

High-Loaded Copper-Containing Catalysts for Furfural Hydroconversion

Abstract

In this paper, high-loaded copper-containing catalysts synthesized by the different methods (sol–gel, fusion, coprecipitation) have been studied in furfural hydroconversion in a batch reactor at a hydrogen pressure of 5.0 MPa and a temperature of 100°C. The reduction temperatures and phase composition of the catalysts have been determined by physicochemical methods. It has been shown that the highest activity in the studied process is exhibited by a coprecipitated copper–alumina catalyst, which provides the production of furfuryl alcohol with a selectivity of 100% at 100–130°C; in addition, in the presence of this catalyst, 2-methylfuran can be synthesized with a yield of 65% at 200°C. The phase composition of the catalyst reduced at a selected temperature and the catalyst after reaction has been determined.
