“…The pressed catalysts were sealed and placed at room temperature for 12 h. Then, they were calcined in the air at 550 o C for 4 h. After that, they were stored in a sealed vial in a desiccator, which can minimize the adsorption of the atmospheric moisture. In this study, the fresh calcined ZSM-5 catalyst was used as a control compared to other catalysts [18].…”

Catalytic cracking of camelina oils to hydrocarbon fuels over ZSM-5 and ZSM-5 impregnated with Zn 2+ (named bifunctional catalyst) was individually carried out at 500 o C using a tubular fixed-bed reactor. Fresh and used catalysts were characterized by ammonia temperature-programmed desorption (NH 3 -TPD), X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and nitrogen isothermal adsorption/desorption micropore analyzer. The effect of catalysts on the yield rate and qualities of products was discussed. The loading of Zn 2+ to ZSM-5 provided additional acid sites and increased the ratio of Lewis acid site to Brøn-sted acid site. BET results revealed that the surface area and pore volume of the catalyst decreased after ZSM-5 was impregnated with zinc, while the pore size increased. When using the bifunctional catalyst, the pH value and heating value of upgraded camelina oils increased, while the oxygen content and moisture content decreased. Additionally, the yield rate of hydrocarbon fuels increased, while the density and oxygen content decreased. Because of a high content of fatty acids, the distillation residues of cracking oils might be recycled to the process to improve the hydrocarbon fuel yield rate.

“…This was lower than that of bio-oil (1.05-1.25 g/mL) [8]. The higher heating value of vegetable oils was high (between 37.1 MJ/kg and 40.6 MJ/kg) when compared to that of bio-oil (16)(17)(18)(19) MJ/kg) [8]. The high energy content of vegetable oil makes it an alternative fuel to replace diesel fuel for a short time use, but the deposition produced by the vegetable oil combustion is an issue for a long time use [4].…”

Abstract:To address the issues of greenhouse gas emissions associated with fossil fuels, vegetable oilseeds, especially non-food oilseeds, are used as an alternative fuel resource. Vegetable oil derived from these oilseeds can be upgraded into hydrocarbon biofuel. Catalytic cracking and hydroprocessing are two of the most promising pathways for converting vegetable oil to hydrocarbon biofuel. Heterogeneous catalysts play a critical role in those processes. The present review summarizes current progresses and remaining challenges of vegetable oil upgrading to biofuel. The catalyst properties, applications, deactivation, and regeneration are reviewed. A comparison of catalysts used in vegetable oil and bio-oil upgrading is also carried out. Some suggestions for heterogeneous catalysts applied in vegetable oil upgrading to improve the yield and quality of hydrocarbon biofuel are provided for further research in the future.

To produce high yield and quality hydrocarbon biofuel, HZSM-5 zeolite loaded with different Zn concentrations (5, 10, 15 and 20wt.%) was used to palm oil cracking in batch reactor. Reaction temperature and reaction time were optimized. The products contained liquid hydrocarbon biofuel, distillation residual and coke. The physical properties of biofuel products were determined. The results presented that 15% Zn/HZSM-5 exhibited higher hydrocarbon biofuel yield (20.27%) and their excellent product properties with higher heating value (HHV), low viscosity and moisture content. A highest hydrocarbon biofuel yield and good alkane range hydrocarbons distribution from palm oil were obtained under reaction temperature of 420°C for 5 hours.
