Hydrocracking of Calophyllum inophyllum Oil With Non-sulfide CoMo Catalysts

Abstract

This research was aimed to convert Calophyllum inophyllum kernel oil into liquid fuel through hydrocracking process using non-sulfide CoMo catalysts. The experiment was carried out in a pressurized reactor operated at temperature and pressure up to 350 o C and 30 bar, respectively. The CoMo catalysts used in the experiment were prepared by 10 wt.% loading of cobalt and molybdenum solutions over various supports, i.e. -Al2O3, SiO2, and -Al2O3-SiO2 through impregnation method. It is figured out from the experiment that non-sulfide CoMo based catalysts have functioned well in the hydrocracking conversion of Calophyllum inophyllum kernel oil into fuels, such as gasoline, kerosene, and gasoil. The CoMo/-Al2O3 catalyst resulted higher conversion than CoMo/SiO2 and CoMo/-Al2O3-SiO2. The fuel yields were 25.63% gasoline, 17.31% kerosene, and 38.59% gasoil. The fuels obtained in this research do not contain sulfur compounds so that they can be categorized as environmentally friendly fuels.

Synthesis and Characterization of Ni/Hydrotalcite and Its Application in Hydrocracking Calophyllum Inophyllum Oil

“…Based on the analysis of biofuels, conversion was 96.26%. This conversion is smaller than the conversion of 10% CoMo/γ-alumina catalyst in the same conditions of hydrocracking [15]. The actual amount of nickel only 7.56%.…”

“…Paraffin compounds were over 40%, consisted of heptadecane and pentadecane. As reported by Rasyid [15], Biofuel from calophyllum inophyllum oil is approaching the characteristics of hydrocarbons including gasoline fractions, diesel oil, kerosene and aromatic fraction with operating conditions at a temperature of 350 °C using a catalyst CoMo with various support catalysts. The fatty acids as the raw material components that not successfully converted in the form of oleic acid by 1.43% area.…”

“…This result is similar to Qi [7] that impregnation of Ni can increase the surface area of the catalyst. Fig.4.a shows the chromatogram of GC-MS of calophyllum inophyllum oil [15] and hydrocracking product at a temperature of 350°C under 20 bar. Components with retention time of 7-19 minutes in the calophyllum inophyllum oil disappear after hydrocracking reaction take place.…”

Effect of Process Parameters on Yield of Biofuel Production from Waste Virgin Coconut Oil

“…There are several conversion methods of vegetable oils into biofuels, such as thermal cracking, catalytic cracking, and hydrocracking [8,9,10,11]. Thermal cracking, a conversion technique of vegetable oil to biofuel, is performed under the condition at high temperature and high pressure in the absence of catalyst.…”

Triglycerides Hydrocracking Reaction of Nyamplung Oil with Non-sulfided CoMo/γ-Al2O3 Catalysts

“…The use of this type catalyst without sulfidation process can prevent the use of toxic substances like H2S and more economical. The hydrocracking using nonsulfidation catalyst produced environmentally friendly liquid fuel [12]. Therefore, the aims of this research are to study the temperature effect in hydrocracking process of the nyamplung oil (Calophyllum inophyllum) using a non-sulfided CoMo/γ-Al2O3 catalyst and to develop a simple kinetic model in interpreting the data of hydrocracking products in a highpressure batch reactor.…”
