Faujasite-type zeolite was synthesized using a microwaves-assisted thermal reaction and ultrasonic waves at different aging times, varied at 0, 7, 21 and 28 days. The iron oxide was synthesized by co-precipitation at low temperature. TheXRDresults showed that zeolite crystallization occurred after 5 days of aging time and achieved uniform crystallinity after 7, 14 and 28 days. The zeolite samples with 7 days of aging time had the smallest particle size (82.1 nm) and the largest specific surface area (304m2 g-1). The FTIR spectrum of the heavy oil indicated a catalyst effect on the breakdown of theC-O,C-CandC-S hydrocarbon chains as well as an increase in transmittance peak in saturated C-HandC-Haromatic bonds. The catalytic test through the aquathermolysis showed that the catalyst with the highest efficiency (81.5%) was found among the zeolite samples with 7 days of aging time (FAU-7). Based on these results, the synthesized catalyst can be used to reduce the viscosity of heavy oils.[/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]Aquathermolysis,Catalyst effects,Catalytic tests,Faujasite type zeolites,Hydrocarbon chains,Low temperatures,Thermal reactions,Zeolite crystallization[/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]Aquathermolysis,Catalyst,Faujasite-type zeolite,Heavy oil,Iron oxide[/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/10.1088/2053-1591/aafc57[/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]
