“…We found the BET specific surface area and the average pore size were 33 m 2 /g and 17.3 Å, respectively, for the magnetite catalyst (Table ). Regarding the HDO catalyst, full characterization of Ni/SiO 2 -Al 2 O 3 is reported elsewhere. , The diffraction peak characteristics of the parent ZSM-5 were observed at 2θ = 22.96, 23.82, 24.32, 45.8, and 64.3° (Figure B), which is in accordance with the previously reported ZSM-5 structure. , The crystalline structure of the ZSM-5, however, did not remained constant after loading with MgO and copper, and calcinations occurred at 575 °C. The Cu/ZSM5-MgO precursors (calcined form) showed MgO and CuO diffraction peaks as shown in Figure C.…”

“…For example, the minimum acceptable volatility specifications for SAE 5W-30, low-30, and 15W-30 engine oils allow maximum evaporative weight losses of 25, 20, and 15%, respectively, by the Noack method . As expected, hydrolysis of WCO increased its Noak volatility from 14.8 to 16.4% (Figure B) because of production of lighter compounds (i.e., free fatty acids and linear oxygenates) than the original WCO . Noak volatility trends during other treatment appeared to follow similar trends both on model fatty acids and WCO biolubricants.…”

The present research and development for lubricant production from vegetable oils rely on traditional (trans)esterification, etherification, and/or chemical modifications of triglycerides and free fatty acids (FFAs). However, the final products suffer from at least one of the following: poor low-temperature characteristics, low oxidation stability, low viscosity index, or poor solubility of additives. This study presents a novel approach to produce biolubricants (BL) from the reaction of waste cooking oil (WCO) and cyclic oxygenated hydrocarbons (COHCs) (cyclopentanone, cyclopentanol, anisole, and 2methylfuran) via a four-step pathway: hydrolysis, dehydration/ ketonization, Friedel−Crafts (FC) acylation/alkylation, and hydrotreatment. Such reactions were successfully demonstrated using model compounds (oleic acid and stearic acid) and actual WCO feedstock. The process resulted in the production of novel BLs that were consisted of molecules with several mutual properties: (1) long and linear hydrocarbon chains, (2) low to zero unsaturation, (3) minimal branching, (4) naphthenic rings and cyclic structures, and (5) polar molecules. We showed that such BLs can be synthesized with pour-point, kinematic viscosity (at 40 °C), viscosity index, and Noack volatility of −12 °C, 47.5 cP, 186, and 17 wt %, respectively.

“…Gasoline typically contains 4-8% alkanes, 2-5% alkenes, 24-40% isoalkanes, 3-7% cycloalkanes, 1-4% cycloalkenes, 20-50% total aromatics (0.5-2.5% benzene). Gasoline includes C5 to C13 hydrocarbons, while diesel includes C14 to C19 [47,48]. Because gasoline contains largely aliphatic and aromatic hydrocarbons, we must adjust the experimental conditions to maximize the aliphatic and aromatic fractions in the upgraded biooil.…”

Nuclear Magnetic Resonance (NMR) involves the study of nuclei immersed in a static magnetic field and exposed to a second oscillating field. Nuclei have two properties; spin properties and charge properties. Pyrolysis oil is created by dry heating biomass in a reactor without oxygen to around 500 degrees Celsius and then cooling it. Pyrolysis oil is a type of tar that includes too much oxygen to be classified as a pure hydrocarbon. One of the most fundamental methods in synthetic chemistry is using NMR to verify chemical structure. In the literature, little attention has been paid to the application of NMR in the authentication of chemical structures. In this study, we present a use case of NMR to characterize pyrolysis oil and authenticate chemical structures. Results show that the elucidation of chemical compositions of bio-oil is essential for the optimization of its processing technology and exploration of its potential application.

“…Brassica carinata seed meal can be considered among the products obtained from the energy supply chain and for industrial use, particularly for producing biodiesel from vegetable oil [8]. The importance of renewable energy sources from crops is evident from the policy of the European Community that, in the last ten years, has promoted a policy of programming and incentives in this sector [9].…”

Brassicaceae products have been extensively studied for their biofumigant activity; despite this, few investigate their effect on soil proprieties. This paper aims to describe the effect on soil fertility by adding the seed meal of Brassica carinata at three different doses corresponding to field dose (3 tons/ha), 10 and 100 fold this dose in organic soil. The organic carbon balance was evaluated by analysing the oxidisable, humified and mineralised carbon fractions. Microbial activity was measured by enzymes linked to the carbon, phosphorous and sulphur cycles—β-glucosidase, phosphatase and arylsulphatase, respectively. The amount corresponding to 30 t/ha was the best solution for the mineralised carbon and humic carbon ratio. In contrast, there was a substantial increase in the organic substance’s mineralisation level at the maximum dose, not offset by a relative rise in humification. No repression was observed in the metabolic activity of the microorganisms, their abundance or the main enzymatic activities and, in the conditions tested, a release of only a volatile isothiocyanate occurred, limiting the biofumigant effect. Therefore, these combined factors allow us to assert that the amendment with this type of material at the intermediate dose could positively affect the phosphorus cycle, the soil structure, and fertility.
