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

Abstract

Biofuel from vegetable oil becomes one of the most suitable and logical alternatives to replace fossil fuel. The research focused on various metal ratio Zinc/Molybdenum/HZSM-5 (Zn-Mo/HZSM-5) catalyst to produce liquid hydrocarbon via catalytic hydrocracking of Ceiba penandra oil. The catalytic hydrocracking process has been applied in this study to crack Ceiba pentandra oil into a gasoil range hydrocarbon using Zn-Mo/HZSM-5 as a catalyst. The effect of various reaction temperature on the catalytic hydrocracking of Ceiba pentandra oil were studied. The Zn-Mo/HZSM-5 catalyst with metal ratio was prepared by incipient wetness impregnation method. This process used slurry pressure batch reactor with a mechanical stirrer. A series of experiments were carried out in the temperature range from 300-400 o C for 2 h at pressure between 10-15 bar. The conversion and selectivity were estimated. The liquid hydrocarbon product were identified to gasoline, kerosene, and gas oil. The results show that the use of Zn-Mo/HZSM-5 can produce gas oil as the most component in the product. Overall, the highest conversion and selectivity of gas oil range hydrocarbon was obtained when the ZnMo/HZSM-5 metal ratio was Zn(2.86 wt.%)-Mo(5.32 wt.%)/HZSM-5 and the name is Zn-Mo/HZSM-5_102. The highest conversion was obtained at 63.31 % and n-paraffin (gas oil range) selectivity was obtained at 90.75 % at a temperature of 400 o C. Ceiba pentandra oil can be recommended as the source of inedible vegetable oil to produce gasoil as an environmentally friendly transportation fuel.

Characterization of 3d-Printing Filament With Extruder Melting Temperature Variation for Bone Implant From Kupang Shell

“…the optimum particle size value of the filament results from the extrusion process occurs at the extruder temperature variables of 70 o C and 75 o C, where the value of the particle size of the filament is obtained which is close to the size of the particle size of the filament in the market, namely at 1.75 mm. The decrease in particle size values at higher temperatures is caused by the presence of burning material and causing residues in the liquefier chamber, as well as contaminating other materials [7]. While the low temperature causes a decrease in the roundness of the filament.…”

“…This is because the temperature in the melting chamber must be kept as close as possible to the melting point of the polymer. If the extruder melting temperature is too high, it can cause residue to form in the melting chamber, causing contamination of the remaining material [7].…”

“…Furthermore, the liquid hydrocarbon product generally contains a rich n-alkanes compound obtained through three complex reactions, namely decarbonylation, decarboxylation, and hydrodeoxygenation. 12 In the matter of the hydrocracking feedstocks, vegetable oils, which mainly contain triglycerides, particularly are attractive renewable resources for producing biofuels. 13 Until now, vegetable oils such as coconut, soybean, palm oil, rapeseed, as well as sunower have been used as biofuel feedstocks via hydrocracking.…”
