“…Several studies on green diesel production employing various heterogeneous catalysts have been conducted. Susanto et al [7] reported the synthesis of renewable diesel from oleic acid as a model compound of triglyceride using a Pd/zeolite-Lampung (clinoptilolite [HEU] type) catalyst at a temperature of 375-400 °C and pressure of 15 bar H2. The results showed 93.34% conversion of renewable diesel, with a selectivity and yield of the C13-C19 fraction of 42.72% and 34.87%, respectively.…”

The Petroleum diesel-based fossil fuel remains the primary source of energy consumption in Indonesia. The utilization of this unrenewable fuel depletes fossil fuels; thus, an alternative, renewable fuel, such as one based on biohydrocarbon from biomass-green diesel-could be an option. In this work, green diesel was produced through the hydrodeoxygenation from palm oil and processed in a batch-stirred autoclave reactor over natural zeolite (NZ) and NZ modified with 3 wt.% Fe metal (Fe/NZ) as heterogeneous catalyst. NZ showed high crystallinity and suitability to the simulated pattern of the mordenite and clinoptilolite phases according to X-ray diffraction (XRD) analysis. The presence of Fe metal was further confirmed by XRD, with an additional small diffraction peak of Fe 0 that appeared at 2θ = 44-45°. Meanwhile, NZ and Fe/NZ were also characterized by Scanning electron microscopy (SEM) with Energy Dispersive X-ray (EDX), X-ray Fluorescence (XRF), and Surface Area Analyzer (SAA). The obtained materials were tested for the conversion of palm oil into diesel-range hydrocarbons (C15-C18) under conditions of 375 °C and 12 bar H2 for 2 h. NZ and Fe/NZ produced a liquid hydrocarbon with straight-chain (C15-C18) alkanes as the most abundant products. Based on Gas Chromatography-Mass Spectrometry (GC-MS) measurement, a higher conversion of palm oil into diesel-like hydrocarbons reached more than 58% and 89%, when NZ and Fe modified NZ (Fe/NZ), respectively were used as catalysts.

“…The amount of catalyst used for the reaction was 50 g and the reaction time was 3 h [7,9,14]. Variables of operating condition of hydrotreating process were pressure of 30−60 bar [3,7,[9][10]12,[16][17] temperature 350−400 °C [2,4,[6][7][8][9][10][15][16][17], and ratio between H2 gas and sample (ranges 0.5−1.0) [15][16]. Physical properties of the product obtained from the hydrotreating process analyzed were the density at 15 °C and the kinematic viscosity at 40 °C.…”

“…Finally, fatty acid is reacted by three kinds of reactions: (1) hydrodeoxygenation (HDO), exothermic reaction, losing oxygen as water and generates n-alkane with the same number of fatty acid carbons, (2) decarbonylation (DCO), endothermic reaction, losing oxygen as CO and water, and (3) decarboxylation (DCO2), endothermic reaction, losing oxygen as CO2. In the DCO and DCO2 mechanisms, nalkane differs one carbon atom than initial fatty acid [6,[10][11][12][13][14][18][19].…”

Hydrotreating process of Sunan candlenut oil by using NiMo-γAl2O3 catalyst has been successfully investigated. Preparation of NiMo-γAl2O3 catalyst by using dipping impregnation method generated catalyst used for hydrotreating process. This method consists of three stages: support activation, impregnation, and calcination. This factors influencing the process including temperature, pressure, and the ratio of Sunan candlenut oil to the H2 gas factor were examined. The hydrotreating product of fuel similar to oil was obtained at a minimum temperature of 380 °C, a pressure of 30–60 bar, and the ratio of the sample to H2 gas of 0.5–1. The diesel fuel from physical properties range for the density of 0.82–0.86 g/cm3, and kinematic viscosity of 2–6 cSt have been fulfilled by hydrotreating result. Gasoline, naphtha, diesel oil, and gas oil products of Sunan candlenut oil were obtained by distillation from hydrotreating process. Sunan candlenut oil fuel qualified fuel requirement.

Currently, fossil fuels are still the primary source of fuel. As has been known, fossil fuel especially aviation fuel is limited resources and can increase greenhouse gas emissions. This condition encourages replacement efforts of avture into bioavture fuel. In this research, bioavture is synthesized through hydrodeoxygenation and catalytic cracking from oleic acid as a model compound using NiMo/Zeolite catalyst. Hydrodeoxygenation carried out under operating conditions: at temperature of 375°C, under 15 bar pressure and for 2.5 hours. The chain of hydrocarbons from the result of hydrodeoxygenation has been cracked by catalytic cracking reaction for 1.5 hours. Variation operating condition used are 360, 375, and 390°C. The liquid product is tested its chemical characteristic, ie acid number, FTIR and GC-MS and its physical characteristics, ie density test and viscosity. Bioavtur that synthesized by catalytic cracking have met the specifications of bioavtur, except the acid number with optimum temperature at 375oC. These conditions with NiMo/Zeolite activated led to dominant yield of 36.32%, selectivity of 38.05%, and conversion of 84.30%. Percentage of yield and selectivity of bioavtur are still low caused by performance of catalyst that is still can not optimum. While, high percentage of conversion caused by high temperature used for catalytic cracking.
