“…Therefore, the 10Ni10W/AC-700 catalyst exhibited the best catalytic performance in the deoxygenation of JO. Compared with other reports [57][58][59][60][61], the catalytic performance of Ni-W 2 C-WC catalyst was close to or even better than that of precious metal catalyst, sulfided catalysts, and most nonprecious metal catalysts reported, as shown in Table 4. The Ni-W 2 C-WC catalyst could obtain a high deoxygenation rate and C 15-18 selectivity at a relatively low temperature and pressure (340 • C and 3 MPa).…”

“…A degree of deoxygenation of 86% [57] NiMoLa/Al catalyst with Ni + W + W2C + WC species had higher deoxygenation capability, indicating that W2C + WC species had deoxygenation capability. Moreover, when the reduction temperature was 700 ℃ and the Ni loading was 10 wt.%, the species were Ni, W2C and WC on the 10Ni10W/AC-700 catalyst and the ratio of the percentage of W2C species to WC species was 1.…”

Tungsten carbide-based materials have good deoxygenation activity in the conversion of biomass. In this paper, catalysts with different nickel–tungsten carbide species were prepared by tuning the reduction temperature and Ni loading, and the effects of these different tungsten carbide species in the conversion of jatropha oil were studied. XRD, XPS, TEM, HRTEM, Raman, H2-TPR, ICP-AES were used to characterize the catalysts. The results suggested that metallic W was gradually carburized to W2C species, and W2C species was further carburized to WC species with the increase in reduction temperature and Ni loading. The obtained 10Ni10W/AC-700 catalyst exhibited outstanding catalytic performance with 99.7% deoxygenation rate and 94.5% C15-18 selectivity, which were attributed to the smallest particle size, the best dispersion, the most exposed active sites, and the synergistic effect of Ni, W2C and WC species.

“…Table 6 shows lower values compared to those found for reactions with stearic acid in the literature. However, it is important to note that the feedstock used by Choi et al 7 and Miao et al 29 is composed of a single fatty acid component, whose reaction at these conditions is already consolidated, attributed to its higher adsorption on the activated carbon support. 31,32 When the results of the catalytic deoxygenation reactions from licuri oil and biodiesel were compared to the reaction from the bio-oil, whose matrix of components is also complex, the yields and selectivity to n -alkanes were higher.…”

Catalytic Deoxygenation of the Oil and Biodiesel of Licuri (Syagrus coronata) To Obtain n-Alkanes with Chains in the Range of Biojet Fuels

Aviation industry has the challenge of halving CO2 emissions by 2050, as compared to 2005. An alternative are drop-in biofuels, which are sustainable and fully compatible with aircraft engines and also can be mixed with fossil jet fuel. Among the feedstock for biojet fuel production, licuri (Syagrus coronata) can be highlighted as most of its fatty acids are in the jet fuel range. Thereby, this work investigated the composition and physicochemical characterization of licuri oil and licuri biodiesel, both with satisfactory results according to international standards, with the purpose of obtaining hydrocarbons in the range of jet fuel from these feedstock, by catalytic deoxygenation. The semi-batch reaction, using a 5% Pd/C catalyst at 300 °C and 207 psi, produced n-alkanes with a conversion of up to 39.2%. The n-alkane selectivity was 80.7%, in addition to CO2 selectivity of 83.4% for biodiesel, indicating the preference for the decarboxylation pathway and also confirming licuri as a potential raw material for biojet fuel.

“…Several studies have used low molecular weight biodiesel to make possible the use of these as aviation biofuels, among the most common is the use of jatropha, palm, camellia (Baroutian et al, 2013;Choi et al, 2018;Lin et al, 2020;Ranucci et al, 2018;Rodrigues Ranucci et al, 2014). These biodiesels have characteristics like density and viscosity similar to traditional aviation fuel (Blakey et al, 2011;Ranucci et al, 2018).…”

Through a review of the bibliographic base was identified the potential and difficulties of using biofuels based on babassu culture for use as aviation biofuel. Babassu palm is one of the most important crops for family farming in the north and northeast of Brazil due to its vast use potential. From babassu oil, by transesterification, good quality biodiesel can be obtained. However, it does not have the properties necessary to be used as aviation biofuel. Researches with biofuels from this culture and cultures with a similar organic profile were analyzed pointing out the feasibility of these biofuels as a mixture in aviation kerosene, nevertheless, these biofuels present several problems when used alone. Among the physical-chemical properties analyzed, the freezing point was a critical factor for not using these biofuels. This review points out the best results to improve the physicochemical properties of babassu biofuels to use as aviation fuel and present an important social factor to this palm uses.
