    • A method of reducing hydroxymethylfurfural (HMF) where a starting material containing HMF in a solvent comprising water is provided. H2 is provided into the reactor and the starting material is contacted with a catalyst containing at least one metal selected from Ni, Co, Cu, Pd, Pt, Ru, Ir, Re and Rh, at a temperature of less than or equal to 250° C. A method of hydrogenating HMF includes providing an aqueous solution containing HMF and fructose. H2 and a hydrogenation catalyst are provided. The HMF is selectively hydrogenated relative to the fructose at a temperature at or above 30° C. A method of producing tetrahydrofuran dimethanol (THFDM) includes providing a continuous flow reactor having first and second catalysts and providing a feed comprising HMF into the reactor. The feed is contacted with the first catalyst to produce furan dimethanol (FDM) which is contacted with the second catalyst to produce THFDM.
    • 提供一种还原羟甲基糠醛(HMF)的方法,其中含有HMF的原料在包含水的溶剂中。 将H2置于反应器中,并使原料与含有至少一种选自Ni,Co,Cu,Pd,Pt,Ru,Ir,Re和Rh的金属的催化剂在小于或等于250的温度下接触 氢化HMF的方法包括提供含有HMF和果糖的水溶液。 H2和氢化催化剂。 在30℃或更高的温度下,HMF相对于果糖选择性地氢化。制备四氢呋喃二甲醇(THFDM)的方法包括提供具有第一和第二催化剂的连续流动反应器,并向反应器提供包含HMF的进料。 进料与第一催化剂接触以产生与第二催化剂接触以产生THFDM的呋喃二甲醇(FDM)。
