A model of the mechanistic reaction kinetic parameters has been developed. The reaction rate model was determined using the rate-limiting step method, which was integrated and optimized to find the most suitable model and parameters. Based on this study, the Langmuir-Hinshelwood reaction rate model with the best correlation is the one where the rate-limiting step is the surface reaction between methane and one adsorbed oxygen atom. The pre-exponential factor and activation energy were 9.19 × 105 and 92.04 kJ/mol, while the methane and oxygen adsorption entropy and enthalpy were -17.46 J/mol.K, -2739.36 J/mol,-16.34 J/mol.K, and -6157.09 J/mol, respectively. © 2013 Published by ITB Journal Publisher.[/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]Fixed bed reactor,Fixed-bed reactors,Langmuir-Hinshelwood,Methane emissions,Oxygen adsorption,Preexponential factor,Rate-limiting steps,Reaction rate model[/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]Catalytic oxidation,Fixed bed reactor,Kinetic parameter,Langmuir-hinshelwood,Methane,Oxidation,Pt/Al2O3[/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/10.5614/j.eng.technol.sci.2013.45.2.7[/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]
