Traditionally, copper chromite has been used in furfural hydrogenation to obtain valuable products, like furfuryl alcohol. However, the presence of Cr poses serious environmental issues, in such a way that different Cr-free catalysts has been proposed as alternative. In this work, two commercial Cu-based catalysts without Cr, currently used in alcohol reforming (R120) and water-gas shift (W220), have been successfully evaluated in FUR hydrogenation to produce selectively furfuryl alcohol. Both R120 and W220 catalysts were characterized, with special emphasis on the elucidation of metallic properties, dispersion and oxidation states of Cu species, and compared to copper chromite. The R120 catalyst attained the best catalytic performance and stability over time, reaching a turnover frequency (TOF) of 0.31 s^-1 at 190 °C, after 1 h of reaction. The catalytic results reported that these Cr-free commercial catalysts have high potential to replace copper chromite as shown the stability test for 24 h.

传统上，亚铬酸铜已用于糠醛加氢以获得有价值的产物，例如糠醇。但是，Cr的存在带来了严重的环境问题，以至于提出了不同的无Cr催化剂作为替代方案。在这项工作中，目前已成功地评估了在醇重整（R120）和水煤气变换（W220）中使用的两种不含Cr的商用Cu基催化剂在FUR加氢中可选择性生产糠醇。表征了R120和W220催化剂，特别着重于阐明铜的金属性质，分散性和氧化态，并与亚铬酸铜进行了比较。R120催化剂具有最佳的催化性能和随时间变化的稳定性，达到0.31  s ^-1的周转频率（TOF） 反应1小时后，在190°C的温度下。催化结果表明，这些无铬工业催化剂具有取代亚铬酸铜的高潜力，如24 小时的稳定性测试所示。
