2-甲基呋喃(2-MF)和环戊酮(CPO)是糠醛的选择性加氢产物，可以用木质纤维素进行工业规模生产。在这项工作中，首先通过 2-MF 和 CPO 的无溶剂羟烷基化/烷基化 (HAA)，然后加氢脱氧 (HDO) 同时合成可再生柴油或喷气燃料范围的支链烷烃和环烷烃。在本工作中使用的固体酸催化剂中，Nafion-212树脂对2-MF和CPO的HAA表现出最好的活性和选择性。 Nafion-212树脂的优异性能归功于该催化剂的高酸强度。 2-MF和CPO的HAA产物在几种镍催化剂上进行HDO后，以高碳收率获得了具有相对较高密度的喷气燃料范围支链烷烃和环烷烃的混合物。与Ni/SiO2相比，酸性载体负载镍催化剂在HDO过程中活性更高，这可能归因于酸性位点对脱水的促进作用。
2-Methylfuran (2-MF) and cyclopentanone (CPO) are the selective hydrogenation products of furfural, which can be produced in industrial scale with lignocellulose. In this work, renewable diesel or jet fuel range branched alkanes and cycloalkanes were first synthesized simultaneously by the solvent-free hydroxyalkylation/alkylation (HAA) of 2-MF and CPO followed by hydrodeoxygenation (HDO). Among the solid acid catalysts used in this work, Nafion-212 resin exhibited the best activity and selectivity for the HAA of 2-MF and CPO. The excellent performance of Nafion-212 resin can be attributed to the high acid strength of this catalyst. After the HDO of the HAA products of 2-MF and CPO over several nickel catalysts, a mixture of jet fuel range branched alkanes and cycloalkanes with relatively higher density was obtained at high carbon yield. Compared with Ni/SiO2, acidic support loaded nickel catalysts are more active in the HDO process, which may be attributed to the promotion effect of acid sites in dehydra...
