Hydrodeoxygenation of benzophenone on Pd catalysts

Hydrodeoxygenation of Phenol Over Hydrotreatment Catalysts in their Reduced and Sulfided States

“…Moreover, alumina is known to be metastable in the presence of water, and will partially transform into boehmite under hydrothermal conditions [18]. To overcome these flaws, catalysts supported on SiO 2 [13,19], active carbon [20], TiO 2 [17], ZrO 2 [17,21,22], zeolites [23], and various mixed oxides [14,24] have been explored in recent years.…”

Ni–La–B amorphous alloys supported on SiO2 and γ-Al2O3 for selective hydrogenation of benzophenone

“…Considering that traditional chemical reduction methods are not usually environmentally friendly [2], selective hydrogenation of benzophenone to benzhydrol over metal catalysts is the preferred protocol. Noble metals including palladium, platinum, and rhodium have been studied extensively for this reaction, but their application is limited due to high catalyst cost or low selectivity to benzhydrol [3][4][5]. Raney Ni has been commonly used in this conversion, but its pyrophoric nature and the consequent serious safety hazards have limited its further application [6].…”

Methods and Applications of Deoxygenation for the Conversion of Biomass to Petrochemical Products

“…It has also been shown that Pd on supports such as carbon, Al2O3, ZSM-5, MCM 41 [76,85,86] are active for HDO. A study conducted with benzophenone with 5% Pd on active carbon and on ZSM-5 supports proved to be very active toward hydrogenation as opposed to supports such as Al2O3, and MCM 41.…”

“…However, the HDO of benzophenone was significantly higher with Pd on supports like active carbon and acid zeolytes. Furthermore, it was concluded that the acidity of the zeolite support affects the HDO reaction [76].…”
