“…Meanwhile the conversion reached 95.54% at 800°C using 0.30 mol/L Ni metal concentration and 94.78% at 700°C using the same Ni metal concentration. This showed that there is an effect of the concentration of metallic Ni which is deposited to open the pores on the catalyst and increase the cracking efficiency (Zhang et al, 2021;Mahmudah & Hari Kusumawati, 2020;Ramadhani et al, 2017). (Endarko & Adawiyah, 2019).…”

According to data from the National Energy Council (DEN) (2016), the energy consumption in Indonesia is increasing every year and will increase 1.8 times in 2025, this requires an alternative energy to back up the energy needs. One such alternative energy strategy is to use biodiesel. Biodiesel can be obtained from Crude Palm Oil using a catalytic cracking process. This study investigated the cracking of Crude Palm Oil using Ni-carbon with ion exchange method. The concentration of the metal solution used was 1, 2 and 3%, with temperature 450, 500 and 550 ° C. The catalyst was analyzed by XRD and showed that the highest pattern at 25.6º on 2% solution. The catalyst characterized by SEM-EDX showed that the nickel metal bonded to the 1, 2, and 3% Ni-Charcoal catalysts was 02.01, 1.13 and 2.09%, respectively and the average of catalytic cracking product conversion at concentrations of 1, 2and 3% was 62.55, 66.52 and 56.50%, respectively.

This study aims to determine the characteristics of Mo-Ni/HZ catalysts and test the ability of Mo-Ni/HZ catalysts in converting vegetable oils into biofuels through catalytic cracking reactions.Catalyst preparation is carried out by the impregnation method which begins with activation of natural zeolite.Impregnation is carried out by dissolution, reflux, filtration, drying and calcination.Catalyst characterization included the determination of the distribution of metals in zeolites using IR spectroscopic analysis and total acidity of the catalyst by ammonia adsorption gravimetric method.Preparation of samples prior to cracking is heating, degumming and bleaching.Catalytic cracking was carried out at 280oC using Mo-Ni/HZ catalyst for 100 minutes.The constituent components of the cracking results were analyzed by GC-MS and IR spectroscopy.The results obtained from the catalytic cracking process were then determined by physical characteristics which included density, viscosity, fog point and pour point test.Based on the shift of wave number in IR spectroscopy, it can be concluded that the Ni and Mo metals are embedded in the HZ.This Mo-Ni/HZ catalyst has total acidity of 8.39 mmol/gammonia.The results of the study prove that the Mo-Ni/HZ experiment proved to be able to crack oil frompalm oil processing wastewater by 91.46% to composition C=O ester CH aliphatic.The physical characteristics of cracking productshave parameters density of 0.93 g/cm3, a viscosity of 26.60 cSt, a fog point of 15oC and pour point of 11.67oC.

“…Optimizing the hydrocracking process necessitates the use of catalysts. Research indicates that catalysts for biofuel hydrocracking vary based on the feedstock type, with key characteristics like porosity, surface area, and crystal size significantly impacting their effectiveness [3,4]. Mesoporous silica, with its orderly, interconnected pore network ranging from 2 to 50 nanometers, is vital in hydrocracking [5].…”

<p>Hydrocracking, a key process for converting waste coconut oil into biofuel, requires efficient catalysts. This study investigates the synthesis of mesoporous silica catalysts using a hydrothermal process. Dodecyl amine, sourced from beach sand, serves as a template. The hydrothermal synthesis involved durations (12, 15, 18, 21, and 24 hours) and dodecyl amine concentrations (0.25 M, 0.5 M, 0.1 M), conducted at 40 °C for 30 minutes. The synthesized catalysts were then characterized for their surface area, pore volume, and diameter. Among the synthesized samples, those treated for 15 hours displayed optimal total acidity at 0.88 mmol/g. The catalysts synthesized with a dodecyl amine concentration of 0.025 M exhibited superior characteristics, including a specific surface area of 233 m²/g, a pore volume of 0.47 cc/g, and an average pore diameter of 2.10 nm. These findings underscore the efficacy of mesoporous silica catalysts in hydrocracking, particularly in converting large hydrocarbon molecules into smaller, more valuable biofuel molecules. Comparative analysis with similar research highlights the significance of these findings in the field of sustainable energy. The optimal catalyst conditions yielded a liquid fraction of over 70% for 0.25 M dodecyl amine. This efficiency in converting waste coconut oil into biofuel signifies the potential of mesoporous silica catalysts in advancing environmentally friendly energy sources. This research contributes to the growing knowledge of renewable energy, offering promising avenues for developing sustainable and eco-friendly energy solutions.</p>
