has been undertaken with the aim of designing promising noble-metal-free catalysts for efficient hydrodeoxygenation (HDO) of dibenzofuran (DBF) into fuel grade hydrocarbons. For this, various Ni/Al-SBA-15 catalysts with different Si/Al (50, 60, 70 and 80) mole ratios were synthesized and their catalytic performance was tested for HDO of DBF in a batch reactor. The catalysts were systematically characterized

hydrodeoxygenation (HDO) of dibenzofuran (DBF) catalyzed by a bimetallic nickel/platinum (Ni/Pt) catalyst in water was demonstrated at 200 °C and 1.2 MPa hydrogen (H2) pressure. The bimetalliccatalysts prepared by a wet chemical method exhibit prominent activity that overcomes the limitations of use of a single Ni or Pt metal catalyst. The yield of HDO products can be up to 90%. Reaction results indicate

Catalytichydrodeoxygenation (HDO) is one of the most effective methods to upgrade the oxygen-containing compounds derived from coal tar to valuable hydrocarbons. Herein, an efficient bimetallic catalyst Pt1Ni4/MgO was prepared and applied in the HDO of dibenzofuran (DBF). High yield (95%) of the desired product bicyclohexane (BCH) was achieved at 240°C and 1.2 MPa of H2. Superior catalytic performance
催化加氢脱氧 (HDO) 是将源自煤焦油的含氧化合物升级为有价值的碳氢化合物的最有效方法之一。在此,制备了一种高效的双金属催化剂 Pt 1 Ni 4 /MgO,并将其应用于二苯并呋喃 (DBF) 的 HDO。在 240°C 和 1.2 MPa 的 H 2下实现了所需产物双环己烷 (BCH) 的高产率 (95%) 。优越的催化性能可以归因于Pt位和Ni位的“接力催化”,并提出了反应途径。还进行了放大实验和可回收性测试,证明了 Pt 1 Ni 4 /MgO的可回收性和潜在的应用前景。
