“…Biodiesel, a favorable alternative fuel acquired sustainably from animal or vegetable fats, is becoming increasingly attractive worldwide due to the depletion of fossil fuels [1,2]. As the unavoidable by-product of biodiesel manufacture, glycerol is growing excessively with the increasing production volume of biodiesel [3][4][5].…”

“…In the last decade, the development of new catalytic technologies that produce liquid transportation fuels from renewables has seen a growing interest due to the depletion of available fossil fuel resources and environmental issues [1][2][3][4][5][6][7][8]. Hydroprocessing of triglyceride-based feedstock, including non-edible vegetable oils, tall oils, animal fats, and waste frying oils is an efficient way to produce diesel and aviation fuel components [3,[9][10][11][12][13].…”

Abstract:The Ni 2 P/SiO 2 catalyst, which was prepared by in situ temperature-programmed reduction and in the mixture with the inert (SiC, SiO 2 ) or acidic (γ-Al 2 O 3 ) material was studied in methyl palmitate hydrodeoxygenation (HDO). Methyl palmitate HDO was carried out at temperatures of 270-330 • C, H 2 /feed volume ratio of 600 Nm 3 /m 3 , and H 2 pressure of 3.0 MPa. Ni 2 P/SiO 2 catalyst, diluted with γ-Al 2 O 3 showed a higher activity than Ni 2 P/SiO 2 catalyst diluted with SiC or SiO 2 . The conversion of methyl palmitate increased significantly in the presence of γ-Al 2 O 3 most probably due to the acceleration of the acid-catalyzed reaction of ester hydrolysis. The synergism of Ni 2 P/SiO 2 and γ-Al 2 O 3 in methyl palmitate HDO can be explained by the cooperation of the metal sites of Ni 2 P/SiO 2 and the acid sites of γ-Al 2 O 3 in consecutive metal-catalyzed and acid-catalyzed reactions of HDO. The obtained results let us conclude that the balancing of metal and acid sites plays an important role in the development of the efficient catalyst for the HDO of fatty acid esters over supported phosphide catalysts.

“…Oxygen can be removed in the form of CO (decarbonylation), CO 2 (decarboxylation) or H 2 O (direct HDO). The main reaction products are C n or C n −1 hydrocarbons, where n is the number of carbon atoms in the hydrocarbon chain of the initial ester or fatty acid . Aliphatic esters, like methyl palmitate (MP) or methyl heptanoate, are usually used as model compounds for comparison of catalyst activity in HDO reactions.…”

BACKGROUND The search for alternative sources of fuels is crucial for sustainable development now and in the near future. Biomass attracts much attention as an environmentally friendly, green and CO2‐neutral source of fuels. Hydrodeoxygenation (HDO) of fatty acid‐based feedstocks such as nonedible vegetable oil, waste cooking oil and animal fat is a versatile technology for producing efficient fuels. HDO schemes are often contradictory and have different numbers of stages. In the work reported, a highly active nickel phosphide catalyst was obtained and methyl palmitate (MP) HDO kinetic modelling was carried out to elucidate the HDO reaction scheme. RESULTS The effect of reduction temperature (400–600 °C) on the catalytic properties of the catalyst in MP HDO was evaluated and the most active catalyst (after reduction at 450 °C) was used in the kinetic experiments. The experimental data were collected in a wide range of MP conversion. The reaction scheme of MP HDO was elucidated by means of mathematical modelling which was specified by successive consideration of the experimental results of HDO selectivities at low MP conversions (1–10%), additional experiments of alcohol HDO (dodecanol‐1 as an analogue for hexadecanol‐1) and analysis of gas‐phase products. CONCLUSIONS In accordance with the results obtained, both hydrolysis of MP and hydrogenolysis of C&bond;OCH3 bond should be considered for describing the conversion of MP to intermediate compounds. This finding could explain the synergetic effect of acid and metal centres, which has been reported in the literature on aliphatic ester HDO, and justify the higher activity of bifunctional catalysts in this reaction. © 2019 Society of Chemical Industry
