Several characterization techniques such as total acid number (TAN), FT-IR spectroscopy, 1H NMR spectroscopy and Karl-Fischer analyses are applied to follow the oxidative evolution of the oil. The results indicate that hydrophilic nanosized FAU zeolite shows the best performance in slowing down the oxidation rate of palm oil, and efficiently limits the production rate of water and black solid polymeric residues. The IR results reveal that zeolite nanoparticles are able to stabilize the oxidative propagation agent such as peroxides, and limit the polymerization products in the palm oil. A mechanism describing the inhibition of palm oil oxidation in the presence of zeolite nanoparticles is proposed. It is suggested that the hydrophilic nanosized zeolites, which can increase the lifetime and quality of palm oil, are potential eco-friendly antioxidant additives in replacing the conventional harmful organic antioxidant in lubricant industry.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Antioxidant additives,Characterization techniques,Framework structures,H NMR spectroscopy,Lubricant industry,Oil based lubricant,Polymerization products,Zeolite nanoparticle[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Antioxidant,Lubricant,Oxidation,Palm oil,Zeolite nanoparticles[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.jtice.2015.06.032[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
