Hydrodeoxygenation of lignin-derived phenolics over facile prepared bimetallic RuCoNx/NC

Construction of a highly active and water-resistant Ni-based catalyst for the HDO reaction of phenol

“…In addition, the data about surface area, pore volume, and pore size are summarized in Table 1. On the whole, the specic area increased from 142 m 2 g À1 for pure Al 2 O 3 to 192 m 2 g À1 for Ni@C/Al 2 O 3 (10) due to the generation of porous carbon with a large specic area in the pyrolysis process. Further increase in Ni loading leads to a decrease in the specic area, which may be due to the coverage of excessive Ni species on the g-Al 2 O 3 support, the partial blockage of the pores, and the easy aggregation of Ni species.…”

“…8,9 The development of highly active catalysts for HDO technology is an important factor but still remains a great challenge. Many kinds of catalysts, such as noble metal catalysts, [10][11][12] metal sulde catalysts, 13,14 metal carbide catalysts 15,16 and transition metal catalysts [17][18][19] are widely used. However, noble metal catalysts are not appropriate for industrial utilization because of their high price, difficult availability, poor reusability and easy deactivation caused by carbon deposition.…”

Solventless hydrodeoxygenation of isoeugenol and dihydroeugenol in batch and continuous modes over a zeolite-supported FeNi catalyst

“…Isoeugenol (IE) and its hydrogenated product, dihydroeugenol (DHE) are used in this work as model compounds, because isoeugenol containing hydroxyl, methoxy and allyl groups, also found in bio-oils derived from lignin, can be considered as a representative lignin model compound. 1,2 Batch-wise HDO of lignin-derived compounds was already performed with noble metals, 1,3,4 noble metal-containing bimetallic catalysts 5,6 and non-noble metal-based catalysts. 2,3,7 As there is an increased interest in industry to use cheap nonnoble metal materials as catalysts, abundant Fe and Ni were selected as active metals.…”

Zeolite imidazolate framework/g-C3N4 derived Co nanoparticles embedded in nitrogen doped carbon for efficient hydrogenation of phenol

“…The decomposition of lignin could obtain phenolic compounds including phenol, guaiacol and their derivatives. 1 The conversion of compounds derived from lignin to value-added chemicals has been widely investigated. 2,3 Particularly, the transformation of phenols derived from lignin to the related alcohols is attracting much attention.…”
