“…The appearance of MoO3 oxide peaks makes it challenging to form active phases after the catalyst undergoes sulfidation (Ulfah & Subagjo, 2012). Based on JCPDS No 5-0506, the characteristic peaks of NiO oxide are located at 2θ angles of 43.46° and 63.11° (Rinaldi et al, 2017). These NiO peaks were not detected in the NiMo/Al-PILC catalyst (Fig.…”

“…Subsequently, H2 gas at atm pressure was introduced into a CS2 solution, producing H2S gas. The generated H2S gas was fed into the catalyst at a temperature of 623 K for 90 minutes (Adilina et al, 2019;Rinaldi et al, 2017). The sulfided catalyst was used for the Hydrodeoxygenation (HDO) reaction of guaiacol.…”

“…The primary goal of pillarization is to modify bentonite's physical and chemical properties, including increasing its surface area, porosity, and thermal stability. Several metal oxides such as Al, Zr, Ti, Fe, and Cr have been successfully used as pillar agents in the bentonite pillarization process and create different physicochemical properties from each other reported in our previous works (Khairina et al, 2022;Rinaldi et al, 2023Rinaldi et al, , 2017. Bentonite pillarization using Ti resulted in the increase in specific surface area from 24.47 m 2 /g to more than 150 m 2 /g and acidity from 0.08 mmol/g to 0.66 mmol/g due to the bond between metals and the alumina-silicate bentonite layer (Khairina et al, 2022).…”

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 issues of global CO2 emissions and depletion of non-renewable energy resources associated with fossil fuels encourage the use of plant oils (both edible and non-edible) as biofuel sources. This review summarizes the literature on renewable hydrocarbon fuel production, including feedstock choice, oil extraction, and production processes. Plant oils can be upgraded into hydrocarbon biofuels by catalytic cracking or deoxygenation reactions, such as hydrodeoxygenation, decarboxylation and decarbonylation. This review also covers current progress in renewable hydrocarbon fuel blending with fossil diesel or gasoline to meet the requirements of product quality for engine fuel applications.

“…synthesized and characterized sulfided NiMo catalysts supported on different mesoporous materials (Al 2 O 3 , TiO 2 , and MCM‐41) and tested them in bio‐oil upgrading. The NiMo/TiO 2 catalyst resulted in the highest deoxygenation degree compared with NiMo/Si‐MCM‐41 and NiMo/Al 2 O 3 , indicating that the acidity of the catalyst could play an important role in HDO [13a] . Recently, Yang et al.…”

Sulfided NiMo/(Al)‐MCM‐41 Catalysts for Anisole Hydrodeoxygenation: Impact of Aluminium Incorporation in the Mesostructured Support

et al. 2022

NiMoS nanocatalysts supported on MCM‐41 modified with aluminium were studied in the anisole hydrodeoxygenation. Our interest was to study the effect of the Al incorporation to the support on the activity and selectivity. The results indicate that the catalytic behaviour strongly depended on the Al presence in the MCM‐41 support and its loading. The anisole conversions and the respective pseudo‐first‐order rate constants increased with Al‐incorporation compared to the NiMo/Si‐MCM‐41 sample. The highest catalytic activity was obtained with the NiMo/Al‐MCM‐41(60) nanocatalyst. Aluminum presence in the support also had a strong effect on the selectivity of the catalysts, promoting the formation of phenol as an intermediate product mainly through demethylation of the O‐CH3 group of anisole, as well as through demethylation of 2‐methylphenol intermediate. These results were ascribed to an increased acidity of the Al‐MCM‐41‐supported samples and the participation of these acidic sites in the interaction with anisole and oxygen‐containing reaction intermediates.
