Nickel catalysts supported on mesoporous clays with different acid properties, such as montmorillonite MK-10, Al-pillared montmorillonite, mesoporous Na-saponite and mesoporous H-saponite, were prepared, characterized and tested for the hydrogenation of furfural to tetrahydrofurfuryl alcohol (THFA). Clays were also modified introducing basicity through magnesium oxide in different amounts. Catalysts with higher acidity or low amounts of metallic centres favoured deactivation and/or selectivity to the non-desired products. Interestingly, the addition of MgO both neutralized the acidity of the montmorillonite supports and improved the hydrogenation of the furanic ring, resulting in higher selectivity to THFA. The best catalyst was the one prepared with montmorillonite MK-10 covered by 30 wt% of magnesium oxide and with 8.8 % of the Ni metal phase achieving total conversion and total selectivity to THFA. The activity of this catalyst was maintained after several reuses.

制备了负载在具有不同酸性质的介孔粘土上的镍催化剂，如蒙脱石MK-10，铝柱状蒙脱石，介孔钠皂石和介孔H皂石，并对其进行了表征，并进行了糠醛加氢成四氢糠醇（THFA）的测试。 。还对粘土进行了改性，从而通过不同量的氧化镁引入了碱性。具有较高酸度或少量金属中心的催化剂有利于失活和/或对不期望的产物的选择性。有趣的是，MgO的添加既中和了蒙脱石载体的酸度，又改善了呋喃环的氢化作用，从而提高了对THFA的选择性。最好的催化剂是用蒙脱石MK-10（覆盖30％（重量）氧化镁和8）制备的催化剂。8％的镍金属相实现了总转化率和对THFA的总选择性。多次重复使用后，该催化剂的活性得以保持。
