“…It is also observed that the surface area and pore volume for LFMO are 2.018 m 2 /g and 4×10 -3 cm 3 /g, respectively. The modal pore width is registered to be 35.5 Å (Figure 3c), which shows that the LFMO is microporous (Asiedu et al, 2019).…”

“…The Brunauer-Emmett-Teller (BET) surface area, the pore volume, and the pore size of the new and used catalysts are measured using Quantachrome (NOVA 200e) surface area analyzer having degassed at 300 o C for 3 hours, adsorbed, and desorbed with N 2 at -196 o C. The surface area is evaluated using a multi-point BET model. The pore size distribution is obtained from the desorption isotherm using Barret-Joyner-Halenda (BJH) model (Asiedu et al 2019;Lowell et al, 2006) while the total pore volume is calculated at a relative pressure (P/P o ) range of 0.0-1.0.…”

Li2FeMn3O8 (LFMO) nanocomposite material for Li-ion battery is synthesized using chemical combustion method. To fabricate a hybrid nanostructure electrode, LFMO is coated on tin oxide (SnO2) nanorods (NR), which is grown using a vapor-liquid solid (VLS) technique on a steel substrate. The surface morphology of the hybrid nanostructure electrode confirms that, single crystalline SnO2 nanorods are grown vertically with spine-like structures, a few microns in length, as evident from field emission scanning electron microscope image. The electrochemical performance of SnO2/LFMO shows very interesting characteristic with enormous charge storage capability. The coin cell shows improved capacity with a higher number of charging and discharging cycles. This SnO2/LFMO hybrid composite electrode shows better specific capacitance value as compared to the pristine SnO2 electrode.

“…Another alternative for jet biofuel production is the in situ catalytic transfer hydrogenation using isopropanol as a hydrogen donor [114]. Despite the large input cost associated with isopropanol [114], the authors previously reported that isopropanol may represent a potential hydrogen donor for the hydroprocessing of waste cooking oil to produce biofuel, reducing or eliminating the use of gaseous hydrogen from an external source [115].…”

Production of Jet Biofuels by Catalytic Hydroprocessing of Esters and Fatty Acids: A Review

The transition from fossil to bio-based fuels is a requisite for reducing CO2 emissions in the aviation sector. Jet biofuels are alternative aviation fuels with similar chemical composition and performance of fossil jet fuels. In this context, the Hydroprocessing of Esters and Fatty Acids (HEFA) presents the most consolidated pathway for producing jet biofuels. The process for converting esters and/or fatty acids into hydrocarbons may involve hydrodeoxygenation, hydrocracking and hydroisomerization, depending on the chemical composition of the selected feedstock and the desired fuel properties. Furthermore, the HEFA process is usually performed under high H2 pressures and temperatures, with reactions mediated by a heterogeneous catalyst. In this framework, supported noble metals have been preferably employed in the HEFA process; however, some efforts were reported to utilize non-noble metals, achieving a similar performance of noble metals. Besides the metallic site, the acidic site of the catalyst is crucial for product selectivity. Bifunctional catalysts have been employed for the complete process of jet biofuel production with standardized properties, with a special remark for using zeolites as support. The proper design of heterogeneous catalysts may also reduce the consumption of hydrogen. Finally, the potential of enzymes as catalysts for intermediate products of the HEFA pathway is highlighted.

“…Because of this potential future energy deficit, researchers have focused much attention on green fuel from triglycerides, which are the main constituents of vegetable oils . Waste cooking oil (WCO), which contains 4-hydroxy-2-alkenal (which is a toxin and a pollutant) and is abundant globally (29 million ton/year), has been used to produce liquid hydrocarbon fuel via decarboxylation (CO 2 release), decarbonylation (CO release), and hydrodeoxygenation (CO 2 and H 2 O release) with an appropriate catalyst and hydrogen gas. − Reported processes of WCO require a large volume of hydrogen handling with a H 2 :WCO ratio in the range of 300–1200 m 3 /m 3 oil, which create potential hydrogen handling and inherent safety cost. − Although hydrogen gas is the best reagent for hydrotreating conventional fuel, it is in short supply and comes from fossil fuel. Since gaseous hydrogen is nonpolar and immiscible with triglycerides at low pressures, there is a problem of mass transfer and diffusion during hydrogenation of triglyceride.…”

“…CTH is advantageous to conventional hydrogenation (use of gaseous hydrogen), because CTH reduces the high cost of transporting and storing large volumes of gaseous hydrogen . Among the hydrogen-donating compounds that have been studied are tetralin, decalin, naphthalene, n -dodecane, formic acid, cyclohexane, and a whole list of hydrocarbon solvents . One of the advantages of using hydrocarbons as in situ hydrogen donors is the lower bond energy of C–H in these solvents compared to that of the H–H bond in H 2 .…”

Process optimization and reaction kinetics of catalytic transfer hydrogenation (CTH) of waste cooking oil (WCO) into jet fuels using zeolite-supported Ni−Co−Mo oxides catalyst in a packed-bed reactor were studied. Experiments were conducted at three different temperatures (360, 390, and 420 °C) to determine the rate constants, the order of reaction, and the activation energy. The kinetics study showed a first-order reaction with the activation energy estimated to be 84 ± 18.7 kJ/mol WCO with 95% confidence. Design of experiment (DOE) was employed to estimate the optimum reaction parameters using the polynomial model (383.7 °C; 14.8 bar; WCO-to-2-propanol ratio = 1.57 mL/ mL; weight hourly space velocity (WHSV) = 6.7 h −1 ). Validation of the model at the optimum operating conditions generated 80% yield of liquid products with 77% alkanes, 3.8% alkenes, and 12.3% aromatics composition, and 6.7% gases, and 100% conversion of WCO. The catalyst was prepared via the wet impregnation method and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Brunauer−Emmett−Teller (BET) adsorption and desorption, scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and thermogravimetric analysis (TGA). Characterization of the catalyst revealed a cubic structure, which was maintained after one cycle of CTH reaction. Present in both the fresh and the used catalysts were Na 2 O, K 2 O, MgO, Al 2 O 3 , SiO 2 , CaO, FeO, Fe 2 O 3 , which highlight the composition of zeolite. The active sites were dominated by Co 3+ , Ni 2+ , and Mo 6+ that were respectively present in the form of Co 2 O 3 , NiO, and MoO 3 .
