Hydrotreatment of sunflower oil using supported molybdenum carbide

Optimization of catalytic hydrodeoxygenation of oleic acid into biofuel using fluoroplatinum oxalate zeolite supported catalyst

“…In this direction, several studies such as effects of different catalyst supports [9,11] and types of metals [12,13], catalyst preparation procedure [14,15] and additives such as sulfur [16] and phosphorus [17] are currently receiving attentions. Among all the catalyst supports studied, zeolites appeared to be more interesting and promising owing to their crystalline structure, well-defined pore shapes and sizes which allow tweaking of catalytic properties and performance [12].…”

Metal Carbides for Biomass Valorization

“…Since then, transition metal carbide has attracted much interest in catalysis and surface science. It has been demonstrated that the catalytic properties of these cheaper metal carbides are comparable to the catalytic properties of the more expensive Pt-groups metals [19][20][21][22]. In the case of dehydrogenation, hydrogenation and hydrogenolysis, which involve a transformation of hydrocarbons' C-H bonds, activities of these metal carbides are similar or better than the activities of Pt-group metals [19,[23][24][25].…”

Effect of precursor acidity on zeolite supported Pd catalyst properties and hydrodeoxygenation activity for the production of biofuel

“…4). The comparably severe loss of crystallinity in the FPd/Z catalyst compared toPd/Z earlier observed in the SEM and XRD results which gave rise to its comparably higher Si/Al ratio (Table 1) Recently in attempt to gain thorough insight into the hydrodeoxygenation (HDO) process of different feed stocks, studies onreaction variablessuch as effects of reaction pressure and temperature, H 2 gas flow rate, catalyst loading and even types of reactors and mode of operations have been well studied and reported [20,[30][31][32][33][34]. However, since existing hydrotreating units of conventional crude oil refineries can be adapted for the HDO process of biofuel production, studies on expedient synthesis of suitable catalysts such as types of the support and metals [34], systematic catalyst preparation procedure [20,26,35]and additives such as sulfur [36]and phosphorus [31]are currently receiving attention.In this direction, we recently, functionalized nickel with oxalic acid and supported on alumina for the hydrodeoxygenation of oleic acid into high grade biofuel [18].…”
