Due to COVID-19, global demand for coal was reduced by 19% in 2020 compared with 2019 [1]. However, the shortage of fossil fuels remains the main problem, as they are immensely used around the world. Therefore, the use of renewable energy should be developed also known as renewable energy such as solar energy, geothermal, hydropower, wind, biomass, and biofuels promoted to replace fossil fuels (such as coal, crude oil, and natural gas) [2]. Currently, biofuel is very attractive due to its high technological potential [3,4] for example low-cost production and high conversion efficiency from biomass. Most biomass resources are derived from waste or the by-products of agriculture, industry, and forestry [5]. In this study, the falling palm fruit was interested to be converted to pyrolytic oil. Falling palm fruits were an agricultural waste. In 2020, the palm production capacity in Thailand was about 15.7 Mtons per year [6]. However, the pyrolytic oil was shown in high oxygen content and high acidity. Therefore, pyrolytic oil needed to be upgraded to biofuel oil with lower oxygen content and acid value. The upgrading of pyrolytic oil to biofuel had been most interesting to many researchers. In this work, the in-situ hydrodeoxygenation (HDO) by using methanol as a hydrogen donor was examined under sub-critical conditions.
This work aimed to upgrade pyrolytic oil derived from falling palm fruits to reduce the acidity and oxygen contents by using in situ HDO. The methanol was selected as a hydrogen donor. The reaction condition was tested at a temperature of 220 °C for 6 h. The effect of different nickel loading (0, 5, 10, 15, and 20%wt) on HZSM-5 (SiO2/Al2O3 = 40) was examined by using the incipient wetness impregnation method. The catalysts were reduced at a temperature of 550 °C for 5 h under an atmospheric of 10% H2 mixed with 90% N2. The physical and chemical properties of catalysts were characterized by XRD, N2 adsorption-desorption, FESEM, EDS, FTIR, and XANES.
The upgrading oil products were analyzed by many techniques such as density, viscosity, HHV, CHNO, and TGA. The best upgrading oil was distilled following ASTM D86 to separate bio-gasoline, bio-kerosene, and bio-diesel. The acidity, density, HHV, and viscosity were done to compare bio-fuel before and after upgrading. The results were shown that NiO/HZSM5 could be successfully reduced to Ni/HZSM5 confirmed by XRD, and FTIR. The morphology of catalysts displayed in a spherical shape and agglomerated in higher Ni loading of more than 10%. The Ni contents were effect by the HDO reaction. The optimal Ni loading was about 10% giving the lowest oxygen content in upgrading oil products. The viscosity and density were decreased after the upgrading process. The in-situ HDO not only reduced oxygen content but also cracked pyrolytic oil. The distilled product of upgrading oil was higher than pyrolytic oil about 15% by volume. The viscosity, density, and HHV were under standard specifications of bio-kerosene and bio-diesel except for acidity. However, the acidity was reduced by more than 60% compared with raw material.
