Hydroconversion of fatty acid derivative over supported Ni-Mo catalysts under low hydrogen pressure

Development of reduced Mo promoted Ni catalysts for biofuels production via hydrodeoxygenation

“…However, a considerable progress is expected concerning this kind of catalysts by investigating the best Ni/Mo or Ni/W ratio which is not necessarily the critical ratio of the sulphided hydrotreatment catalysts. Very recent results presented in the present work are confirming this prediction [171,172].…”

Remarkably reducing carbon loss and H2 consumption on Ni–Ga intermetallic compounds in deoxygenation of methyl esters to hydrocarbons

“…In the Ni-based bimetallic catalysts, a second metal (such as Fe [17] , Cu [15] , Zn [19] , Sn [15] , Mo [16,20] ) modifies the geometric and electronic properties of metallic Ni, and the Ni-based alloy or intermetallic compound (IMC) usually forms. In this case, Scheme 1.…”

“…The former is desirable because the small Ni ensembles restrain the C -C bond hydrogenolysis [21] . Particularly, when the second metal (e.g., Fe [17] , Zn [19] , and Mo [16,20] ) is higher oxophilic than metallic Ni, the HDO pathway is remarkably promoted. This is very important from the view point of increasing carbon atom utilization.…”

“…In contrast to the oxophilic metals, Cu scarcely affected the deoxygenation pathway on the Ni catalysts [16,26] . In addition, the bimetallic Ni-M (M = Cu, Zn, Mo) catalysts were also less active for methanation than the monometallic Ni ones [19,20,26] . It is worth noting that, compared with Ni-Zn alloys, Ni-Zn IMCs were more effective for suppressing C -C bond hydrogenolysis and methanation [19] .…”

Role of NiMo Alloy and Ni Species in the Performance of NiMo/Alumina Catalysts for Hydrodeoxygenation of Stearic Acid: A Kinetic Study

“…Hence, these catalysts have been reported extensively for this reaction by various research groups. 4,29−34 For example, HDO of C 17 –COOH was studied over SiO 2 , γ-Al 2 O 3 , and HZSM-5-supported Ni catalyst. 4 The C 17 alkane was reported as the main product over Ni/γ-Al 2 O 3 .…”
