“…isomerization, cracking, hydrotreating are targeted simultaneously in a single reactor catalyst bed with a catalyst having strong hydrogenation/dehydrogenation ability along with tailored acidity for these reactions [1,25,31]. The unsaturations in the hydrocarbon chains of triglycerides drive cyclization and condensation reactions, under acidic reaction conditions [36,37], further dehydrogenation (at sulfided metal sites) produces aromatics over this multifunctional catalyst system. High exothermicities observed during these simultaneously occurring reactions in a single reactor [38] may also be one of the reasons for the production of aromatics and naphthenes in the present process.…”

“…In particular, the presence of strong acidic sites is beneficial for DCO 2 reaction [21]. Verma et al [22] studied the hydroprocessing of jatropha oil over the hierarchical SAPO-11 with different acidities, finding that the increased acidity in catalyst increased the DCO 2 and/or DCO reaction selectivity.…”

“…This tree can reach a height of 6-15 m which is part of the ecosystem of mangrove forests [1]. However, this vegetable oil can not be used directly as biofuel because they still contains high oxygen atoms, high viscosity, high freezing point, low heating value, and thermal instability [5,6].…”

“…Typical catalysts for catalytic cracking or hydrocracking of triglycerides can be categorized into several types: (1) molybdenum-based sulfide/non-sulfide catalysts, such as NiMoS, CoMoS, CoMo/γ-Al2O3, NiMo/ZSM-5-alumina, and NiMo/SAPO-11 [2,6,7,[13][14][15][16], (2) Ni/Zn catalyst supported on HZSM-5 [14,17], (3) noble metals, including Pd/Pt catalyst supported on HZSM-5 [18]. Organic liquid product obtained can be divided into groups of gasoline, kerosene and gasoil.…”

The effect of various reaction temperature on the hydrocracking of Cerbera manghas oil to produce a paraffin-rich mixture of hydrocarbons with Co-Ni/HZSM-5 as doubled promoted catalyst were studied. The Co-Ni/HZSM-5 catalyst with various metal loading and metal ratio was prepared by incipient wetness impregnation. The catalysts were characterized by XRD, AAS, and N2 adsorption-desorption. Surface area, pore diameter, and pore volume of catalysts decreased with the increasing of metals loading. The hydrocracking process was conducted under initial hydrogen pressure in a batch reactor equipped with a mechanical stirrer. The reaction was carried out at a temperature of 300-375 o C for 2 h. Depending on the experimental condition, the reaction pressure changed between 10 bar and 15 bar. Several parameters were used to evaluate biofuel produced, including oxygen removal, hydrocarbon composition and gasoline/kerosene/diesel yields. Biofuel was analyzed by Fourier Transform Infrared Spectroscopic (FTIR) and gas chromatography-mass spectrometry (GC-MS). The composition of hydrocarbon compounds in liquid products was similar to the compounds in the gasoil sold in unit of Pertamina Gas Stations, namely pentadecane, hexadecane, heptadecane, octadecane, and nonadecane with different amounts for each biofuel produced at different reaction temperatures. However, isoparaffin compounds were not formed at all operating conditions. Pentadecane (n-C15) and heptadecane (n-C17) were the most abundant composition in gasoil when Co-Ni/HZSM-5 catalyst was used. Cerbera Manghas oil can be recommended as the source of non-edible vegetable oil to produce gasoil as an environmentally friendly transportation fuel.
