“…The FT-IR spectra of the original carbohydrates are in good agreement with those previously reported in the literature. 62,63 For cellulose and hemicellulose, the strongest bands can be seen in the range between 1034 and 1112 cm −1 , which correspond to -C-O vibrations assigned to sugars. 62 In addition, for hemicellulose the vibrations for the β-glycosidic bonds are also important.…”

“…The summation of constituent proportions must be equal to one, and the number of the constituent factors should be at least three, when using the simplex-lattice design method [12]. The mass concentrations of the organic compounds were in the range of 0.5 $ 3.5 wt% (the mass ratio of the organic compound to the whole solution).…”

“…The method could ensure the well distribution of the design points and had a good performance in evaluating the effects of constituent factors on the desired response. The summation of constituent proportions must be equal to one, and the number of the constituent factors should be at least three, when using the simplex-lattice design method [12]. In this section, gas yields and TOC removal efficiencies were selected as the response surfaces (dependent variables).…”

Phenol, acetic acid, and naphthalene, as the most common and refractory intermediates during the supercritical water gasification (SCWG) of biomass were selected as the model compounds, and the their mutual interactive effects during the SCWG process were investigated. The gasification performances of one‐component solutions and their two‐ and three‐components mixtures were thoroughly studied in a tubular reactor at 550°C, 25 MPa, reaction time of 20 s. Results showed that for the one‐component solutions, the difficulty degree of degradation order of the three compounds was naphthalene > phenol > acetic acid, and concentration of the reactants showed little influence on the gasification efficiencies. For the two‐components solutions, acetic acid promoted the degradation of phenol and naphthalene, and the gasification of phenol and naphthalene inhibited each other. The 3D curved surface for gas yields and total organic concentration (TOC) removal efficiencies of three‐components mixture clearly showed that the increasing concentration of acetic acid increased the H2 and CO2 yields. While the interactive effects of the three compounds were favorable for CH4 yield. Acetic acid played a positive effect on TOC removal, while the increasing concentration of naphthalene was unfavorable for the degradation of TOC, and the inhibition effect was higher when phenol existed. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1140–1148, 2018

Intermediate pyrolysis on desert date (Balanites aegyptiacus) shell (BAS) was accomplished for the first time to authenticate the biomass potential for producing quality biomaterials such as bio-oil and biochar. Fourier transform infrared spectroscopy (FTIR), elemental analysis, and gas chromatography-mass spectrometry (GC-MS) were employed to examine the compositions of the resultant biooil. The FTIR spectrum revealed the functional groups of oxygenated compounds like aldehydes, alcohols, phenolics, acids, and esters in the bio-oil. GC-MS confirmed that the bio-oil has diverse compositions of oxygenated compounds rich in acids, phenolics, and benzene derivatives. From the ultimate analysis, the bio-oil had a higher carbon content and a lower oxygen content than the corresponding BAS sample. The calorific values, by comparison, were higher than that of the BAS sample but lower than for fossil fuels. The favorable outcomes from the characters of the bio-oil and biochar suggested that BAS can be an attractive feedstock to produce high-value biomaterials.
