“…This particle size range is the suitable one to carry out fast pyrolysis in a Py-GCMS, where very small quantities of sample are used, of around 1 mg. A thermogravimetric analyzer (TGA Q5000 IR) was used in this study to determine the proximate analysis of the DPS samples. The procedure was described elsewhere [33].…”

“…Effect of the HZSM-5 catalyst at 450 °C Figure 6 shows the percentages of the peak areas obtained for the components in the pyrolysis stream without catalyst and with different amounts of HZSM-5 zeolite catalysts at 450 °C. Thermal pyrolysis of DPS was conducted in a previous study in the same reactor [33].…”

Catalytic pyrolysis of date palm seeds (DPS) has been carried out in a pyroprobe connected online with a GC/MS. The effect of a HZSM-5 zeolite on the product distribution has been studied at 450 and 500 °C by using different catalyst/biomass mass ratios (1, 2, 5) and that of a dolomite catalyst at 450 °C using a catalyst/biomass mass ratio of one. Product distributions have been monitored and their trends explained based on the properties of the catalysts used. The HZSM-5 promotes the formation of incondensable gases and aromatic hydrocarbons due to its high acidity and shape selectivity. The concentrations of incondensable gases and hydrocarbons increase markedly with the catalyst/biomass mass ratio, with their peak area percentages ranging from 23.6 to 54.1% and from 7.1 to 24.5%, respectively. At the same time, a significative reduction in the amount of acids, ketones, phenols, furans, and anhydrosugars has been determined. The dolomite catalyst enhances ketonization reactions, which leads to a significant increase in the content of ketones, accounting for a value of around 27%.

“…However, the accessibility of IRMS standards along with standardized methodology is the foremost goal to be addressed in present (Khatri et al, 2023). The coupling of analytical pyrolysis with gas chromatography-mass spectrometry (Py-GCMS) involves the decomposition of sample through pyrolysis/heating for the production of smaller compounds that can be separated by gas chromatography and detected by mass spectrometry (Bensidhom et al, 2021).The identification of compounds present in the sample is done through a characteristic pattern of fragmentation, requiring huge database availability for recognition and elucidation of structure of chemical compounds. Py-GCMS improved the structural illustration of compounds, and with integration with other methods in multi-proxy approach, offered a high-resolution molecular data with regard to component analysis of organic matter.…”

Soil organic matter (SOM) plays a crucial role in soil health, fertility, and carbon cycling, making its accurate estimation essential for sustainable agriculture and ecosystem management. However, the quantification of SOM is fraught with methodological challenges that can introduce variability and uncertainty into assessments. Traditional techniques may lack specificity and accuracy, while advanced methods pose challenges related to calibration and standardization. The selection of an appropriate method is critical and requires careful consideration of soil characteristics, land use, and research objectives. This article reviews the key methodological challenges associated with estimating soil organic matter, aiming to provide an understanding of the complexities involved, and provides insights on the latest instrumentation for SOM measurements.

“…8,9 The heterogeneous and complex structural characteristics of lignin, including C-O bonds (β-O-4, α-O-4, α-O-γ, 4-O-5), C-C bonds (β-5, β-β, β-1, 5-5), a complex three-dimensional configuration and intra-and inter-molecular π-π interactions, make it difficult to generate products with regular structures. [10][11][12] The highly selective conversion of lignin becomes a recognized challenge, although various processes were developed, including acid/base catalysis, 13 enzymatic hydrolysis, 14 pyrolysis (thermolysis), 15,16 oxidation, 17 reduction (hydrogenolysis), 18 etc. Among these widely investigated methods, oxidation has been the most commonly used lignin depolymerization method, which is technically employed in the modern pulp bleaching processes.…”
