Sugar palm bunch/SPB (Arenga longipes Mogea) waste is a lignocellulosic material derived from the harvest of sugar fruit (kolang-kaling). Therefore, this study aims to examine anatomical, physical, chemical, and mechanical characteristics SPB. The anatomical characterization results showed that SPB had two forms fibrovascular bundles (FVBs), namely large small. Based on morphology, fibers length, diameter, average lumen cell wall thickness approximately 1346.42 ± 415.71 μm, 20.05 3.81 11.82 2.95 4.12 1.08 respectively. FVB tissue sample fairly high density 4–6 per 4 mm2 with non-vascular area/total area ratio 57.25%. contained 45.31 3.20% cellulose, 23.21 3.73% hemicellulose, 27.23 4.23% lignin, 1.39 0.32% ash content. In addition, extractive content dissolved in hot water, cold ethanol-benzene, 1% NaOH was 4.79 0.84%, 7.12 0.68%, 7.27 2.38%, 29.81 3.78%, GC–MS analysis A. bunch several compounds, including carboxylic acid (tetradecanoic, octadecanoic), methoxy group (3-hydoxyphthalide), palmitic acid. Meanwhile, FTIR presence OH groups intensity, which were identified as aromatic groups, well phenol recognized lignin. these results, more suitable raw materials for biomass energy, absorbent activated carbon, composite board, surfactant.

Camel dung (CM) and date stone (DS) are biomass resources that abundant across the Gulf region have potential to produce sustainable renewable fuels specialty products. Copyrolysis of CM with DS is an intriguing research approach boosting both production quality pyrolysis products, particularly biochar. The current study investigated bio-energy CM, DS, CD-DS blend by assessing their physicochemical attributes, characteristics, kinetic behaviour using thermodynamic analysis. To investigate behaviour, materials were thermally decomposed a thermogravimetric analyser under non-isothermal conditions at different heating rates in nitrogen environment. findings analysis established feedstocks for long-term energy generation. Thermal degradation profiles samples revealed multistage due various components structure. While positive synergistic effect between CD was observed thermal profile blend. average apparent activation from Friedman method, Flynn–Wall–Ozawa (FWO) model, Kissinger–Akahira–Sunose (KAS) Starink model 324, 167, 157, 158 kJ/mol, respectively. Friedman, FWO, KAS, methods yielded energies 621, 315, 276, 279 kJ/mol mean estimated 210, 216, 206, 207 outcomes reveal slow specified nonspontaneous process requiring external degradation. this may aid better understanding reaction processes expansion applications CD, mix.

Catalytic pyrolysis of date palm seeds on HZSM-5 and dolomite in a pyroprobe reactor in line with GC/MS

Biomass Conversion and Biorefinery, Год журнала: 2022, Номер 14(2), С. 2799 - 2818

Опубликована: Март 11, 2022

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

Several techniques are available for converting biomass into energy and/or valuable chemicals. This study aimed to perform the pyrolysis of sunflower seed husks (SSH) analyze volatile products. Analytical fast experiments SSH were carried out under four different conditions: pure in a helium atmosphere (CGHe); hydrogen (CGHi); with ex situ HZSM-5 (proton exchanged Zeolite Socony Mobil-5) zeolite (CG-ZeHe); and (CG-ZeHi). For each experimental condition, at 450, 550, 650 °C, products analyzed Py-GC/MS (micropyrolysis coupled gas chromatography–mass spectrometry) system. The results showed that zeolitic catalyst presented great effect on organic functions volatiles selectivity distribution, especially formation hydrocarbons. could promote deoxygenation reactions volatiles, enabling generation improved vapors. In CG-ZeHi, production hydrocarbons achieved maximum 42% peak area 550 °C.
