Eucalyptus wood chips were reacted under supercritical water conditions to evaluate the effect of a NiFe2O4 catalyst, residence time and temperature parameters. Experiments were performed in a batch reactor at 400 C, 450 C and 500 C using three different amounts of catalyst (0, 1.0, 2.0 g) and three different residence times (30, 45, 60 min). Results showed that eucalyptus wood chips reacted and produced CO2 as the dominant gas in all cases, followed by H2 and CH4. However, the presence of NiFe2O4 catalyst led to a 60% increase in H2 produced, while significantly reducing the solid residue and enhancing the percentage of methyl derivatives in the organic liquid products. The highest H2 mol% was at 450 C, 2 g of catalyst and 60 min of residence time. Analysis of the derived oils showed that they were mostly composed of ketones, aldehydes, methylbenzenes and alkylated phenols. Increasing the reaction temperature to 500 C increased the molar composition of methane by 62% compared to its yield at 450 C. In generally, this work showed that NiFe2O4 acted as an effective heterogeneous catalyst for improved production of H2 and CH4 via supercritical water gasification process.

Sardinian abbamele is a typical product obtained from the honey recuperation from combs (traditional procedure) or by concentration of the honey diluted in water (industrial procedure). Seven abbamele samples were obtained to study the volatiles’ composition, the presence of honey marker compounds and their relationship with the production procedures. The long thermal treatment applied in abbamele production caused very high (1007.0-4405.8mg/kg) HMF content (HPLC-DAD), while glucose and fructose amounts were quite similar to the honey ones (HPLC-RI). Total antioxidant activity (FRAP assay) of the samples ranged between 13.3 and 71.2mmol Fe2+/kg, while antiradical activity (DPPH assay) ranged between 3.8 and 23.3mmol TEAC/kg. Such high antioxidant values were linearly correlated with total phenol amount (1297.8-4469.5mg GAE/kg) determined by Folin-Ciocalteau method. Thermally derived furan derivatives and terpenes were abundant among the headspace volatiles (HS-SPME), particularly limonene (0.5-76.0%) that probably originated from citrus rinds’ addition during abbamele production. GC and GC-MS analyses of USE isolates revealed HMF predominance as well as the honey marker compounds (if/when existing) such as methyl syringate (up to 49.2%), marker of Asphodelus microcarpus honey. High isophorone percentage (up to 30.9%) determined by HS-SPME followed by minor percentage of 4-ketoisophorone and norisoprenoids in one sample indicated Arbutus unedo L. honey use in the production. HPLC-DAD analysis confirmed the presence of specific honey markers: two samples showed high methyl syringate concentrations (150.4-120.1mg/kg) while homogentisic acid and other specific markers of A. unedo honey were found in one sample. The compared GC-MS and HPLC-DAD data proved to be useful to obtain information about the use of specific honey in the production and to verify citrus addition.

The curing of the Matrimid 5292 polyimide system was studied by pyrolysis-gas chromatography/mass spectrometry. Pyrolysis products characteristic of both initial components and the cured polymer were identified. Changes in the pattern of pyrolysis products could be related to the progress of polymerization. Amounts of methylphenol isomers (m/z 108), 4-succinimido-4?-aminodiphenylmethane (m/z 265), and 2-(2-propenyl)-4-methylphenol were found to increase as degree of cure increases. Amounts of O,O?-diallyl bisphenol A (m/z 293) produced by pyrolysis decreased with increasing cure. Principal component and canonical variate analysis were used to visualize systematic trends in selected ion intensities from the pyrolysis data. Loading weights derived from orthogonal canonical variate analysis were also found to be useful in identifying pyrolysis products related to percentage cure. These results support the use of Py-GC/MS for monitoring the degree of cure of polymer systems.

The Verbascum L. genus (Scrophulariaceae) is rich in phenols, flavonoids, and iridoid glycosides, which have been used extensively in traditional medicine. This study aimed to examine the association between genetics and metabolomics of V. songaricum populations (VSPs), collected from different geographical regions of Iran for further breeding and exploitation programs. Inter-simple sequence repeat (ISSR) analysis showed a significant difference among the twelve studied VSPs, which were classified into five main groups based on an unweighted pair-group method with arithmetic and principal coordinate analysis. Ninety-six bands were produced by fourteen ISSR primers, among which 92.7% of them were polymorphic at the species level. The essential oils were analyzed by means GC?FID and GC?MS and five main chemotypes, including docosane (I), methyl chavicol (II), methyl eugenol (III), beta-damascenone (IV), and alpha-bisabolol (V) were characterized. HPLC?PDA?MS was further used to detect and to measure the phenolic compounds and harpagoside content in methanolic extract of VSPs. The main compounds identified in the VSPs extracts were rutin, quercetin, rosmarinic acid, salicylic acid, ferulic acid, p-coumaric acid, 2, 5-dihydroxybenzoic acid, 3, 4-dihydroxybenzoic acid, and harpagoside. Cluster analysis based on phytochemical data divided VSPs into nine groups. Subsequently, data were analyzed by multiple regression analysis to identify the correlation between genetic and metabolic diversity. The phytochemical data as the dependent variable showed significant association with bands obtained from molecular data. The high variation observed in essential oils, phenolics, and harpagoside among the VSPs establish a good potential to select the best genotype in breeding projects.

Upgrading of bio-oil extracted from palm kernel shell (PKS) was performed using a lab-scale fixed-bed reactor with HZSM-5 as a catalyst. The catalytic cracking was carried out at optimized conditions: 0.3-MPa pressure, temperature of 500C, and oil to catalyst ratio of 1:5. One of the challenges in upgrading bio-oil by catalytic cracking is deactivation of catalyst due to coke formation on catalyst surface. To overcome coke deposition, the upgrading process was carried out at 0.3-MPa pressure. Characterization of raw and upgraded bio-oil obtained through catalytic cracking was discussed in detail, indicating improvement in its physical properties. The distribution of products after cracking of bio-oil includes 58.89 wt% of organic liquid product, 15.63 wt% of aqueous fraction, 7.84 wt% of coke, and 17.64 wt% of gases. The degree of deoxygenation and calorific value of organic liquid product is 43.74% and 31.65 MJ/kg respectively. Organic liquid product obtained comprises 17.55% of hydrocarbons within the gasoline range. Hence, HZSM-5 proved its effectiveness for upgrading the bio-oil in a continuous mode.

The objective of this study was to investigate the effects of water tolerant Lewis acids (i.e., In(OTf)3, Yb(OTf)3 and InCl3) on bio-oil and solid residue yields. For this purpose, poplar wood was liquefied at 300 C with a residence time of 10 min without and with water tolerant Lewis acids in various concentrations from 0.5 to 10 wt% under hydrothermal conditions. The use of water tolerant Lewis acids had negative effects on bio-oil yields. The bio-oil from the run without a catalyst had a value of 17.50 wt% at 300 C, 10 min. The highest bio-oil yields under identical conditions were the following: 14.27 wt%, 13.37 wt% and 12.42 wt% for Yb(OTf)3 (with a concentration of 0.5 wt% of the raw material), In(OTf)3 and InCl3 (with concentrations of 1 wt% of the raw material). The concentrations of catalysts used in the experiments had significant effects on both bio-oil and solid residue yields. An increase of catalyst concentrations resulted in a decrease in bio-oil yields. The catalysts changed neither the molecular nor the elemental compositions of bio-oils and solid residues significantly. The prominent compounds in bio-oils from all runs including the run without a catalyst were phenol, 2,6-dimethoxyphenol, and 2-methoxyphenol.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C9H8O, you can also check out more blogs about4265-25-2

Thermal behavior of different types of biomass, namely forestry – Eucalyptus globulus sawdust, Norway spruce (Picea abies) thermo mechanical pulp; agricultural – energy grass, Brassica rapa, and by-products – pine cones, grape seeds, was evaluated by thermogravimetry and by analytical pyrolysis. The liquid products from pyrolysis were analyzed by gas chromatography coupled with mass selective detector, Fourier transform infrared spectroscopy and by nuclear magnetic resonance spectroscopy. The elemental analysis and the calorific values of the pyrolysis residues were investigated. It has been established that the pyrolysis products consisted mainly of carboxylic acids, ketones, furans, phenols, guaiacols, catechols, and their derivatives, resulting from the degradation of the main structural components of biomass. The distribution of compounds in oils was strongly depended on biomass source, differences in the pyrolysis behavior among the biomass samples being found.
