“…Aldehyde and the carboxylic acid group were observed only in bio-oil from rapeseed meal (9.50.0 ppm, 0.8%). 13 C NMR spectra calculations are presented in Table 4. A decrease in oil content in the pyrolysis raw material results in increased content of large, more chemically complex components in biooils.…”

“…Spectroscopic techniques like FT-IR spectroscopy can give insights into the functional groups present in the bio-oils, but only in a qualitative measure. Few studies have used 1 H and 13 C NMR to obtain approximate ratios of the chemical environments of protons and carbon atoms and determined the approximate aromatic/aliphatic ratio [10,11]. There are few studies on the chemical composition of biooil extracted phases (e.g.…”

“…Several articles have mentioned liquid fractions obtained from biomass pyrolysis being the potential raw materials for liquid fuel production [2,12]. Various methods of refining them are proposed, among others by catalytic cracking and hydrodeoxygenation [13][14][15]. The problem is that in the case of catalytic cracking processes, the proposed catalysts facilitate decarboxylation and removal of oxygen in the form of CO 2 but are deactivated and require continuous regeneration by oxidative removal of coke [16][17][18].…”

“…The analytical studies of liquid products obtained from rapeseed, its meal and cake pyrolysis provided the detailed chemical composition of the tested bio-oils. Special emphasis was put on elemental analysis and precise 13 C NMR spectra analysis. This study is useful for optimizing the hydrorefining process to produce liquid fuel components used as heating oil or engine fuel.…”

On the basis of the 1 H, 13 C NMR and FT-IR spectroscopic results, elemental analysis and acid hydroxide group content analysis, the chemical structure of liquid fractions from pyrolysis of rapeseed treatment products was discussed. All the examined pyrolysis products contain a large number of unstable olefins as well as oxygen and nitrogen in aromatic rings or side hydrocarbon chains in aromatics. Although the liquid fractions obtained by pyrolysis of rapeseed and rapeseed processing products are potentially valuable fuel or fuel components, they need refining treatment. The best method, in this case, seems to be the hydrorefining process. It was shown that the hydrotreatment of such a complex composition requires incurring the costs of hydrogen for refining and construction costs of relevant installations or using existing ones in the nearest refinery. The costs of biofuel production from studied liquid pyrolysis products and other biomass-derived fractions should include the raw material costs as the logistics, i.e. transport of biomass and pyrolytic oils to the place of their pyrolysis or refining. In many cases, the costs of producing liquid fuels by biomass pyrolysis can be comparable or even higher than the value of the biofuel produced.

Developing efficient catalysts for biomass hydrodeoxygenation into high-quality biofuels and chemicals is a current topic of great interest. In this study, Ni 2 P catalysts supported on different zeolites (MCM-41, HY, Hβ) were fabricated for vanillin hydrodeoxygenation by one-pot method instead of temperature-programmed reduction (TPR). The prepared catalysts were characterized using XRD, XPS, NH 3 -TPD and N 2 physisorption. The results showed that the support has a significant influence on the reactivity of the Ni 2 P-based catalyst. The Ni 2 P/HY catalyst contains a higher acid site density, which leads to the almost complete conversion of vanillin to the quantitative yield of 2-methoxy-4-methylphenol (MMP) via direct hydrogenolysis path at 220 °C, 5 h and 2 MPa of H 2 .
