“…Additionally, the formation of a well-dispersed CeAlO 3 phase hindered the growth of filamentous carbon [245]. The role of CeO 2 as a promoter was also studied by Dobosz et al [252], who evaluated its addition to a calcium hydroxyapatite (HAp)-supported cobalt catalyst. During the TOS stability test, which was carried out at 800 • C for 6 h, the catalyst doped with ceria (10Co-Ce/Hap) was stable than the 10Co/Hap catalyst.…”

The renewability of glycerol has made it an appealing medium for the processing of various compounds. Selective dehydration of glycerol to acetol is one of the promising glycerol valorizations. The performance and recent progress of those typical and most frequently mentioned catalysts for the synthesis of acetol from glycerol, including noble metals and transition-based metals, are summarized in detail. A Cu-based catalyst is identified as an appropriate catalyst for the synthesis of the glycerol dehydration route. In addition, advances in process development of several solid supports, the effects of catalyst preparation methods of suitable supports on catalytic activity, and the performance of catalysts' considering the catalytic conversion of glycerol to acetol are reviewed.

“…For instance, Zhang et al studied the transfer hydrogenation of fatty acids on Cu/ZrO 2 catalysts in the methanol/water system at 350 °C. Compared to Cu-based catalysts, Co-based catalysts usually exhibited a more encouraging performance in various hydrogenation reactions due to the high resistance to deactivation. , Therefore, Co-based catalysts may display massive potential in the catalytic transfer hydrogenation of fatty acid methyl esters. Hydroxyapatite (HAP), as a catalyst or support, shows many excellent properties, such as good thermal stability, low water solubility, acid–base properties, and high surface area. − Miao et al reported that the O atom of water could bind with Ca 2+ cations and the H atom of water could bind with O atoms of PO 4 3– , which strengthens the adsorption of water on the HAP surface and results in a strong reactivity of water to electrophiles (such as CO).…”

Octadecanol Production from Methyl Stearate by Catalytic Transfer Hydrogenation over Synergistic Co/HAP Catalysts

As a potential alternative for fossil feedstocks, renewable natural oils are highly desirable for producing fuels or high added-value chemicals. Herein, catalytic transfer hydrogenation of methyl stearate to octadecanol using methanol and water as hydrogen donors was investigated over Co/ hydroxyapatite (HAP) catalysts synthesized by distinct methods. Multicharacterizations revealed that the strong interaction between Co and the HAP support of the Co/HAP catalysts could enhance the electron transferability, resulting in the excellent methyl stearate conversion (94.8%) and octadecanol selectivity (67.7%) at 290 °C in 5 h. The characterizations and density functional theory (DFT) calculations confirmed that the combined Co 0 /Co δ+ active sites could synergistically boost the generation of H 2 and the hydrogenation of methyl stearate in the methanol/water system. In addition, the effects of various reaction conditions (e.g., the amount of methanol, reaction temperature, reaction time, and catalyst loading) were investigated in detail to understand the plausible reaction pathways. The results may have guiding significance on designing catalysts for efficient conversion of fatty acid methyl esters.
