Deoxygenation of pyrolysis vapor from palm fruit cake over NiMo/γ-Al2O3 catalyst: Effect of CeO2, TiO2, and ZrO2 additives

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

“…33 Metal oxides (such as Al 2 O 3 , TiO 2 , CeO 2 and ZrO 2 ) are recognized as proper HDO supports due to their acidity. 5,[34][35][36] It is worth noting that a certain amount of water can be produced during the HDO reaction, which will be adsorbed on these hydrophilic supports and occupy some active sites, thus decreasing the catalytic activity. Therefore, the hydrophobicity of the catalyst remains to be improved.…”

LiCoO2 impregnated nano-hierarchical ZSM-5 assisted catalytic upgrading of Kraft lignin-derived liquefaction bio-oil

“…nickel, zinc, molybdenum, and cobalt have also received special focus due to their immense potential for deep deoxygenation with minimum hydrogen consumption and carbon loss. [14][15][16][17][18] For instance, fast pyrolysis of lignin over cobalt oxide embedded on HZSM-5 provided it with decent catalytic behavior for direct deoxygenation of lignin. 19 Besides, cobalt nitride supported on nitrogen-doped carbon has been quite promising for hydrodeoxygenation (HDO) of lignin-derived phenols under mild conditions.…”
