A cleaner process for hydrocracking of jatropha oil into green diesel

Development of nickel based catalysts for the transformation of natural triglycerides and related compounds into green diesel: a critical review

“…In view of the above the effort to develop NiMo, CoMo or NiW non-sulfided catalysts supported on γ-alumina with an activity similar to the corresponding sulfided catalysts seems to be plausible. In this context interesting contributions devoted to the improvement of the catalytic behavior of the reduced form of the aforementioned catalysts have been recently reported mainly by Professor Rong group [181][182][183][185][186][187][188]. This is mainly attempted by introducing additional phases in the catalyst formulations (Table 5).…”

“…As it can be seen in figure 36 the C 15 -C 18 yield over this catalyst remains practically constant at least for 160h on stream. Liu et al [185,186] extended their efforts to improve, by doping, the catalytic behavior of the reduced form of the conventional hydrotreatment catalysts concerning SDO. They synthesized a nickel, phosphorous, tungsten catalyst supported on γ-alumina (Ni-HPW/Al 2 O 3 ) and tested in the SDO of Jatropha oil to produce green diesel (Table 5, entry 4).…”

Mo influence on the kinetics of jatropha oil cracking over Mo/HZSM-5 catalysts

“…The refining process aimed at decreasing this acid content raises the cost of the final product [5]. Catalytic hydrocracking of jatropha oil is an alternative route to transesterification that generally makes it possible to obtain a drop-in biofuel [6,7]. But this hydrocracking process consumes a significant amount of hydrogen.…”

Zn-Mo/HZSM-5 Catalyst for Gasoil Range Hydrocarbon Production by Catalytic Hydrocracking of Ceiba pentandra oil

“…Inedible vegetable oil as biofeed can be best choice to solve the issue of competition between the use of vegetable oil as the source of food and that of the fuel. Therefore, some of inedible oil have been investigated and reported [6][7][8][9][10][11]. One type of vegetable oil that can be utilized to synthesize bio-hydrocarbons is Ceiba pentandra seed oil.…”

“…The process method of catalytic hydrocracking is the incorporation of catalytic cracking process with the addition of H2 gas. The method is capable of producing biofuels at high temperatures (300-400 o C) and requires more energy for the process of cracking vegetable oils into hydrocarbons, but producing products that have high oxidation stability and cetane number [10]. The catalytic hydrocracking process involves a hydrodeoxygenation reaction as the main reaction and decarboxylation as a side reaction [13].…”
