A preliminary study of the conversion of rosin oil to fine chemicals through hydrocracking reactions using Ni-Mo/Î³-Al2O3 catalysts has been studied. The purpose of this study was to determine the effect of temperature, initial pressure of hydrogen gas, and reaction time to the reaction of hydrocracking of rosin oil to produce fine chemicals. Hydrocracking of rosin oil is performed on a batch autoclave reactor by varying the reaction temperature (300-350 Â°C), hydrogen gas pressure (10-40 bar), and reaction time (60-240 min). The amount of Ni-Mo/Î³-Al2O3 catalyst used is 1% w/w of rosin oil. The results showed that the compounds contained in rosin oil experienced hydrocracking reaction with the use of high reaction temperature. The use of low hydrogen gas pressure is able to split of rosin oil into fine chemicals, whereas the long reaction time results in the rosin oil being crushed producing more products. The hydrocracking reaction of rosin oil using Ni-Mo/Î³-Al2O3 catalyst produces the optimum product if high temperatures used with low hydrogen gas usage and reaction time are used relatively long.

Currently, much attention is devoted to produce bioethanol based on lignocellulosic materials for alternativefuels. Production of bioethanol from lignocellulosic generates black liquor as a waste during the pretreatmentprocess. The black liquor has a potential to produce platform chemicals. Conversion of black liquor into platformchemicals was carried out by hydrothermal liquefaction by involving water as reaction medium at 200275 C.Through the hydrothermal process combined with water at high temperature, catalytic role could be taken over bysodium sulfate. Increase in temperature up to 275C, activity of water combined with sodium sulfate also increasedin decomposition of block chemicals containing in the black liquor. The black liquor was converted into oxygenatedcompounds, such asphenol, propylene oxide, butyrolactone, and quaiacol. The chemicals were recovered as23, 16, 11 and 8 mol%, respectively.

Research on a subject of the preparation of Ni-Mo catalyst on pillared clay support by wetness impregnation method will be investigated in laboratory. The metal concentration of Mo, which will be treated, is roughly 20 %wt and of Ni is 3 %wt. Due to using MoO3 as the metal active catalyst; therefore the support has to contain a specific surface area more than 210 m2/gr in order to achieve the high dispersion of active metal on the support. Also, the effect of the pH of the Mo impregnation solution to the metal active dispersion and activity for Coker naphtha hydrodesulfurization (HDS) will be studied. Characterization of the catalyst will be conducted by using X-ray Diffraction, FT-Infrared, X-ray fluorescence and nitrogen sorption measurement. It is found that the surface area of the support is generated almost 280 m2/gr by pillarization with the oxide composition of the catalyst was 12%-wt of MoO3 and 1.4%-wt of NiO. NiMo-PILC pH-10 catalyst had higher dispersion of active metal on the support than NiMo-PILC pH-1 catalyst. On NiMo-PILC pH-10 catalyst, there was a substantial part of Mo species in the interlayer space of the Al-pillared lay, probably in interaction with the alumina pillar. Â Although, it has to be more detail investigated. From the result of the activity test for Coker naphtha HDS showed that NiMoÂ PILC pH-10 catalyst had slightly higher activity than NiMo-PILC pH-1 catalyst. However, the both of catalyst still had not good enough activity if compare with the commercial catalyst.Keywords: Montmorillonite-Pillared Clay, Ni-Mo catalyst, PreparationÂ AbstrakÂ Suatu penelitian mengenai preparasi katalis Ni-Mo pada penyangga lempung berpilar dengan metoda impregnasi basah dirancang dan dilakukan dalam skala laboratorium. Konsentrasi logam Mo yang digunakan sebesar 13%-b MoO3 dan logam Ni 4%-b NiO. Karena fasa aktif katalis yang digunakan adalah MoO3 maka luas permukaan penyangga yang dibutuhkan adalah lebih besar dari 210 m2/gr guna mendapatkan dispersi yang tinggi. Selain itu, dipelajari juga efek pH larutan impregnasi Mo terhadap dispersi fasa aktif dan aktivitas katalis pada reaksi hidrodesulfurisasi coker nafta. Karakterisasi katalis berpenyangga dilakukan dengan menggunakan alat difraksi sinar-x, FT-IR, XRF serta dilakukan pengukuran luas permukaan spesifiknya. Dari penelitian ini, didapatkan luas permukaan penyangga lempung berpilar sebesar 277 m2/gr dengan komposisi okasida katalis NiMo yang dihasilkan adalah 12%-b MoO3 dan 1.4%-b NiO. Katalis NiMo-PILC pH-1O memiliki dispersi logam aktif yang lebih tinggi pada penyangga jika dibandingkan dengan katalis NiMo-PILC pH-1. Selain itu, pada katalis NiMo-PILC pH-10 ditemukan adanya sebagian logam Mo yang masuk kedalam ruang interlayer dari lempung, yang diduga menjadi pilar. Namun hal ini harus diteliti lebih detail. Hasil uji aktivitas katalis pada reaksi HDS coker nafta menunjukan bahwa katalis NiMo-PILC pH-10 memiliki aktivitas yang lebih tinggi jika dibandingkan dengan katalis NiMo-PILC pH-1.

The characterization on Cr/Bentonit and Zeolit HZSM-5 catalysts for ethanol catalytic process to biogasoline (equal to gasoline) has been done in this study. Cr/Bentonit has high acidity and resistant to a lot of moisture, in addition to being able to processing feed which a lot of moisture (>15%) from ethanol-water mixture, it is also not easy to deactivated. Cr/Bentonit which is then used as the catalyst material on the process of ethanol conversion to be biogasoline and the result was compared with catalyst HZSM-5 zeolite. Several characterization methods: X-ray diffraction, Brunauer Emmett Teller (BET), thermogravimetry analysis (TGA), and catalyst activity tests using catalytic Muffler instrument and gas chromatography-mass spectrometry (GC-MS) for product analysis were performed on both catalysts. From acidity measurement, it is known that acidity level of Cr/Bentonit is the highest and also from XRD result, it is known there is shift for 2theta in Cr/Bentonit, which indicates that Cr-pillar in the Bentonite can have interaction. It is also supported by BET data that shows the addition of specific surface are in Cr/Bentonite compared with natural Bentonite before pillarization. Futhermore catalyst activity test produced the results, analyzed by GC-MS, identified as butanol and also possibly formed hexanol, decane, dodecane, undecane, which are all included in gasoline range (C4 until C12).

Bio-crude oil is known to be sustainable, eco-environmentally, and an alternative energy source produced by biomass pyrolysis. However, its quality remains relatively low due to a higher oxygen concentration compared to liquid fuels from fossils. Therefore, an upgrading process is necessary through the catalytic hydrodeoxygenation (HDO) process. This work synthesized pillared bentonite using Al and Ti metals as the pillaring agent to produce Al-PILC and Ti-PILC as catalyst support for sulfided NiMo. Their catalytic activity in HDO reaction using guaiacol as a model compound of bio-crude oil were also evaluated. Characterization of the bentonite-pillared materials, including Al-PILC, Mo/Al-PILC, NiMo/Al-PILC, Ti-PILC, Mo/Ti-PILC, and NiMo/Ti-PILC, was performed using Surface Area Analyzer, X-ray Diffractometer (XRD), Temperature-Programmed Desorption of ammonia (NH3-TPD), X-Ray Fluorescence (XRF), and Scanning Electron Microscope (SEM) techniques. The characterization results confirm the pillarization process of bentonite using Al and Ti metals as the pillaring agent, and the preparation of the NiMo catalyst using the stepwise impregnation method was successfully prepared. The NiMo/Ti-PILC catalyst performs a superior conversion value on the HDO guaiacol reaction than other catalysts. A well dispersion of Mo and Ni metals on the surface support (NiMo/Ti-PILC), thus creating numerous active sites of the catalyst after the sulfidation. Variations in time and temperature during the HDO guaiacol reaction significantly affected the conversion.

The conversion of fatty acids into bio-hydrocarbons can be carried out through a deoxygenation (DO) reaction. Catalytic deoxygenation of fatty acids can occur through three reaction pathways: decarbonylation, decarboxylation, and hydrodeoxygenation. In this study, three kinds of silica were prepared: (i) silica obtained from the rice husk ash (RHA); (ii) synthetic mesoporous silica SBA-16; and (iii) commercial silica. All prepared silica was used as supported nickel (Ni) catalyst for bio-hydrocarbon production through DO reaction of oleic acid. The objective of this study was to investigate the effect of variations of silica on the reaction pathway and final products composition of DO reaction of oleic acid. The catalysts were characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), surface area analysis, and NH3-temperature-programme desorption. Based on XRF and XRD analysis results, it can be concluded that nickel was successfully impregnated into all silica. All samples of catalysts were used in a reaction carried out at temperature of 285 °C under a pressure of 40 bar H2 for 2h. The results showed that all catalysts were able to convert oleic acid to bio-hydrocarbon with differences in products composition. The highest oleic acid conversion of 98.25% was achieved with Ni/RHA catalyst but the obtained liquid products was the lowest among other catalysts. It is found that this phenomenon was closely related to the acidity properties of the catalyst.

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.

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.
