In 2021, Due to the increase in emissions of harmful gases into the environment, the use of fossil fuels has decreased significantly. The complete combustion of fuel produces carbon dioxide (CO2) which is the main reason for global warming. [1] Next, United Nations Climate Change Conference (UNFCCC COP 27) Carbon dioxide enters the atmosphere, causing global warming and affecting global energy consumption. Our goal is clean and renewable energy, which can replace fossil fuels, namely biofuels. This can reduce emissions into the environment. [2] For this work, the researchers select In-situ hydrodeoxygenation process in subcritical conditions to produce pyrolysis oil because have recently received considerable attention to upgrading pyrolysis oil from biomass and can reduce the oxygen content and acidity of pyrolytic oil well.
Thus, the aim of the present work was to upgrade the pyrolysis oil (PO) by reduction of oxygen content from pyrolytic catalysis cracking (PCC) of waste cooking oil (WCO) using in-situ hydrodeoxygenation. Methanol was an in-situ hydrogen donor. The nickel contents were examined at 0, 3, 6, 9, 12, 15, 18, and 21 wt% over HZSM-5 support (SiO2/Al2O3 = 40). The reaction was tested under a temperature at 230 °C and time 6 h. The Ni/HZSM-5 catalyst was prepared by the incipient wetness impregnation method (IWI). The calcination was done under air atmosphere at 500C and 5 h. Then, catalysts were reduced at a temperature of 550°C for 5 h under 10 vol% H2 mixed with 90 vol% N2 atmosphere before usage. The chemical and physical properties of catalysts were characterized by Thermogravimetric Analyzer (TGA), XRF, N2 adsorption-desorption, XRD, FE-SEM, EDS, FTIR, XPS, and XANES to compare before and after reduction of catalysts. The properties of upgrading oils, such as total acid number (TAN) (ASTM D664), density (ASTM D1480-07), viscosity (ASTM D445 D240), and HHV were analyzed Also, the components, weight loss, and functional group of products were also investigated by CHNO, TGA, and FTIR analyzers.
For the result of upgrading pyrolysis oil, Fig.1 shows the Van Krevelen diagram that represents the mole ratio of H/C and O/C of PO, Raw material (WCO), and Petroleum oil (Gasoline, Kerosene, and Diesel) reacted by the HDO process as displayed in Table 1. The results at 15%Ni/HZSM-5 show a lower O/C and H/C mole ratio when compared with raw material. Therefore, the 15%Ni/HZSM-5 was considered the most promising content to reduce the O content via in-situ HDO, and the result of HDO generated hydrogenation and deoxygenation at the same time. [3]
The morphology of catalysts displayed in a spherical shape and agglomerated in higher Ni loading of more than 15%Ni/HZSM-5. The optimal Ni loading was about 15% giving the lowest oxygen content in upgrading oil products. However, the reduced oxygen contents by more than 73% compared with raw material.
