Abstract

In this paper, the catalysts (Nano-HZSM-5 and Fe-La/nano HZSM-5) were prepared with incipient wetness impregnation and applied for hydrocracking of Sunan candlenut oil. The hydrocracking process was conducted in a batch reactor with a pressure of 20-30 bar H2 gas for 2 h under various temperatures. The results demonstrated that hydrocracking of Sunan candlenut oil using nano HZSM-5 and Fe-La/NHZ catalysts could be converted into aromatic hydrocarbons, and the reaction temperature affected hydrocarbon production. The aromatic compounds, such as propyl-benzene, 1-ethyl-3-methylbenzene, heptyl-benzene, 2-ethyl-naphthalene, etc., reached 35.51% over the Fe-La/NHZ_2 catalyst. In all cases, the zeolite-based catalysts are the most suitable to produce aromatic hydrocarbons. Metal impregnated (Fe and La) on nano HZSM-5 catalyst could improve the aromatics compounds due to increased metal and acid sites. Copyright © 2024 by Authors, Published by BCREC Publishing Group.

Abstract

This study aims to produce diisopropyl ether (DIPE) via isopropanol dehydration using cobalt-phosphate-supported natural zeolite catalysts. The catalytic activities of the zeolite/CoO and zeolite/Co(H2PO4)2 were compared. The as-prepared catalysts were assessed using X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDX), Fourier transform infrared (FTIR) spectroscopy, and N2 adsorption-desorption. Surface acidity was determined using the gravimetric method with pyridine as the probe. The results of this study showed that natural zeolite was favorably impregnated by CoO and Co(H2PO4)2 species. The impregnation process affected the textural and acidic features of the catalysts. The zeolite/Co(H2PO4)2 catalyst with a loading of 8 mEq.g-1 exhibited the highest surface acidity of 1.827 mmol.g-1. This catalyst also promoted the highest catalytic activity towards isopropanol dehydration, with an isopropanol conversion of 66.19%, DIPE selectivity, and yield of 46.72% and 34.99%, respectively. The cobalt phosphate species promoted higher catalytic activity for isopropanol dehydration than the CoO species. This study demonstrated the potential of cobalt phosphate-supported natural zeolite catalysts for DIPE production with adequate performance.

Abstract

Ethylene glycol, a crucial compound extensively utilized in solvents, coolants, antifreeze, polyester fiber production, and as a natural gas-drying agent, can be synthesized via the hydrogenation of ethylene carbonate. In this study, the synthesis, characterization, and catalytic performance of Cu-Ni/SiO2 catalysts for this reaction, utilizing silica (SiO2) derived from rice husk ash, were investigated. Silica was impregnated with copper (Cu) and nickel (Ni) by varying the weight ratio (Cu:Ni = 10, 7:3, 3:7, 10) to prepare bimetallic catalysts. X-ray Diffraction (XRD) analysis confirmed the presence of both Cu and Ni phases in all the catalysts. The 3Cu7Ni/SiO2 catalyst displayed the lowest reduction temperature and the largest surface area (257.97 m²/g). The 7Cu3Ni/SiO2 catalyst exhibited the highest acidity (1.91 mmol/g) and superior metal dispersion, as confirmed by the Field Emission Scanning Electron Microscopy - Energy Dispersive X-Ray (FE-SEM-EDX) analysis. Catalytic activity was evaluated in a batch reactor under 40 bar H2 pressure at 150 °C for 3 h with a catalyst-to-ethylene carbonate ratio of 5:1. Among the catalysts examined, the 7Cu-3Ni/SiO2 composition demonstrated the highest catalytic performance, achieving 15.14% conversion of ethylene carbonate and 80.51% selectivity towards ethylene glycol.

Abstract

Natural bentonite from Pacitan - Indonesia as a support in the preparation of Ti and Zr-pillared metal catalysts (Ti-Zr/bent) for esterification reaction were studied. The preparation of Ti-Zr/bent catalyst was prepared to find out the effect of molar ratios (Ti:Zr) where an investigation was performed in the esterification of waste cooking oil. The catalyst was varied as follows: 0.5:1 (Ti-Zr-1/bent), 1:1 (Ti-Zr-2/bent), 1.5:1 (Ti-Zr-3/bent), 2:1 (Ti-Zr-4/bent), and 5:1 (Ti-Zr-5/bent) were used to determine the yield. The reaction was carried out for 3 hours at 150°C and a pressure of 40 bar N2 gasses. The result of the Ti-Zr/bent catalyst was given increasing significantly for surface area of 133–147 m²/g compares to bentonite 27 m²/g and 10 times of acidity. The best catalyst was shown in 2:1 of ratio Ti:Zr (molar) on esterification reaction with succesfuly performed about 80.40% of yield. Copyright © 2025 by Authors, Published by BCREC Publishing Group.

Abstract

The present study evaluates the catalytic activity of SiO2/Al2O3‒x and SiO2/Al2O3‒x‒NiMo (where x = 5, 10, 25 g of aluminium weight) synthesized using a potassium hydrogen phthalate (KHP) template-assisted route for the hydrocracking of crude palm oil (CPO) into biofuels. Increasing Al weight modified acidity, porosity, and NiMo dispersion, leading to distinct catalytic behavior. The optimal SiO2/Al2O3‒x‒NiMo catalyst (10 g Al) achieved ~94% conversion, dominated by jet fuel-range hydrocarbons (C10-C14) through synergistic hydrodeoxygenation and acid-catalyzed cracking-isomerization pathway. The enhanced performance originates from the balance between acidity and metal dispersion, highlighting that both template selection and Al loading govern the design of efficient SiO2/Al2O3‒NiMo catalysts for biofuel production.
