Glucose dehydration to HMF and its hydrogenolysis to DMF, a suitable biofuel, have been studied using the same catalysts for both processes. The 10CuZr catalyst shows the highest HMF yield (25.6%) with an acceptable glucose conversion (75.8%) after 1.5 h on stream. By increasing the time on stream from 1.5 to 5.5 h the HMF yield (33.2%) and glucose conversion (94.5%) are improved. In the case of DMF production, the 15CuZr catalyst shows the highest DMF yield (30%). This behavior is notably improved when Ru is added to the 15CuZr catalyst, reaching a DMF yield of 45.6%. These activity results could be related to the higher amount of Cu⁰ species exposed on the catalyst surface and the increase of coke resistance. Finally, the 1Ru15CuZr catalyst is used in DMF production using glucose derived HMF as raw material, and a DMF yield and HMF conversion of 16.4% and 77.5% are achieved, respectively.

5-羟基甲基糠醛的氢解反应在ZrO ₂负载的Cu和RuCu催化剂上生产2,5-二甲基呋喃

两种方法都使用相同的催化剂研究了葡萄糖脱水成HMF以及氢解成DMF（一种合适的生物燃料）。在运行1.5小时后，10CuZr催化剂显示出最高的HMF收率（25.6％）和可接受的葡萄糖转化率（75.8％）。通过将运行时间从1.5小时增加到5.5小时，HMF产量（33.2％）和葡萄糖转化率（94.5％）得到改善。在生产DMF的情况下，15CuZr催化剂显示出最高的DMF收率（30％）。当将Ru添加到15CuZr催化剂中时，该行为得到了显着改善，达到了45.6％的DMF收率。这些活性结果可能与较高的Cu ⁰含量有关物种暴露在催化剂表面并增加了耐焦炭性。最后，将1Ru15CuZr催化剂用于以葡萄糖衍生的HMF为原料的DMF生产中，其DMF收率和HMF转化率分别达到16.4％和77.5％。
