Abstract

The increasing demand for crude oil or fossil fuel as a raw material for oil fuel has been steadily rising over time in line with the development that is taking place in Indonesia. However, biofuels are potential vegetable fuels that can be developed as alternative energy because they are renewable and can be renewed to overcome the energy crisis in the future. For this purpose, a double metal catalyst (impregnated with nickel and lanthanum), is used to make biofuels from sunflower seed oil. The effect of metal ratio on the yield of biofuel products is the concern in this study. The temperature of hydrocracking process was 250-330 ℃ with ratio of metal 5% and 10% (metal ratio 1:1 and 1:2). X-ray diffraction (XRD) shows that natural zeolite has a clinoptilolite phase, X-Ray Fluorescence (XRF) shows that acid and base activation increases the Si/Al ratio from 4.5 to 5, Scanning Electron Microscope – Energy Dispersive X-Ray (SEM-EDX) shows images of natural zeolite surfaces in the form of aggregate pieces, and Brunauer Emmett Teller (BET) shows that acid and base activation increases SBET from 29.96 to 49.73 m2/g and forms a hierarchical natural zeolite. The impregnation of Ni-La/Zeolite catalyst has been successfully carried out using the incipient wetness impregnation method and the best catalyst results were obtained, namely Ni-La/Zeolite 10% (1:2) with a surface area of 15.33 m2/gS. The addition of Nickel and Lanthanum metals caused a decrease in the surface area and average pore diameter of the zeolite. The lowest surface area and average pore diameter were found in the variation of the Ni-La/Zeolite 10% (1:2) catalyst, namely 15.33 m2/g and 13.99 nm. The highest hydrocarbon yield was found in the hydrocracking process with the Ni-La/Zeolite 10% (1:1) catalyst with gasoline, kerosene and gasoil fractions of 0.91; 0.39 and 8.32 (%wt), respectively. The hydrocarbon compound composition of the catalyst includes n-paraffin 4.43%, isoparaffin 0.21%, cycloparaffin 2.99% and olefin 2.71%.

Abstract

Hydrotalcite (HT) is a type of clay mineral belonging to the group of layered double hydroxides (LDHs) or anionic clays, which has a layered structure like brucite (Mg(OH)₂), but some of the divalent cations (such as Mg²⁺) are replaced by trivalent cations (such as Al³⁺). HT as a heterogeneous catalyst is particularly attractive because it is easy to separate and resistant to high temperatures. HT as a catalyst can be used in hydrocracking reaction to produce biofuel. Metal impregnation on HT is very promising to enhance catalytic activity especially with the bifunctional mechanism of catalyst. Ni-V metal impregnation has been successfully carried out on HTc using wet impregnation method which is indicated by the results of X-Ray Diffraction (XRD) which shows the emergence of typical peaks of both metals and HTc in 2θ = 35‒70⁰ for HTc, 2θ = 37.22⁰ (NiO) and 37.35⁰ (V2O5) regions, 2θ = 43.58⁰ for NiO, 2θ = 61.26⁰ (V) and 63.07⁰ (Ini). Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX) show a shape that is consistent with the characteristics of HT, namely the shape of the particles layered overlapping each other. In addition, the particle size of HTc is quite small with a scale of 1 μm indicating a particle size of hundreds of nanometers. EDX mapping shows that Ni and V have been dispersed evenly on the HTc surface. Based on the results of N2 adsorption-desorption isotherms, it shows that mesopores are formed which are characterized by hysteresis loops. Ni-V metal impregnation increases the surface area up to 19.915 m2/g and the pore diameter up to 37,642 nm. The results of the Waste Cooking Oil (WCO) hydrocraking reaction show that Ni-V metal impregnation can reduce the carboxylic acid composition up to 67.81% and increase hydrocarbons up to 15% at 10% Ni-V/HTc 1:2.

Abstract

The increasing global demand for sustainable aviation fuels has driven extensive research on developing efficient heterogeneous catalysts. This study investigates the effect of different surface functionalization methods of mesoporous SBA-15 on its catalytic activity for the production of a C16 precursor of bio-aviation fuel. The SBA-15 surfaces were modified by two acid functionalization routes, namely sulfonation and sulfation, to enhance its surface acidity and catalytic activity. Sulfonation was carried out using 3-mercaptopropyltrimethoxysilane (MPTMS) followed by oxidation to obtain the SO3H–SBA-15 catalyst containing sulfonic acid groups (–SO3H), while sulfation using ammonium sulfate as a precursor produced the SO4–SBA-15 catalyst containing sulfate groups (SO42-). Both catalysts were characterized using NH3-TPD and acid-base titration to quantify the total acidity. The catalytic performance was evaluated through hydroxyalkylation-alkylation (HAA) reaction between 2-methylfuran (2-MF) and methyl isobutyl ketone (MIBK) to synthesize a C16 bio-aviation fuel precursor, 5,5′-(4-methylpentane-2,2-diyl) bis(2-methylfuran) abbreviated as MPM. The results revealed that both modification methods effectively increased the total acid of SBA-15. However, the sulfated SBA-15 catalyst exhibited superior catalytic activity and stronger acid strength than the sulfonated one due to formation of more acid sites on its surface. Therefore, the sulfation route was identified as a more effective strategy for developing highly active solid acid catalysts. This research demonstrates the superior properties of sulfated mesoporous SBA-15 as a promising and sustainable heterogenous catalyst for converting biomass-derived platform chemicals into advanced C16 bio-aviation fuel precursors.
