چکیده    Como/rgo and nimo/rgo catalysts were synthesized by incipient wetness impregnation (iwi) method and were evaluated in the oxidative desulfurization (ods) process of dibenzothiophene (dbt) in n-decane as a model feed# in this research citric acid (ca) was used as a chelating agent# three parameters including total metal loading, co or ni/mo ratio and ca/mo molar ratio were investigated in order to achieve optimal conditions toward synthesis# different catalysts were prepared and characterized through the powder-xrd, icp, ftir, raman spectroscopy, bet-bjh, and nh3-tpd analyses# the sulfur content of the product was measured by the icp-oes method and the structure of the product was evaluated using ftir and 1h-nmr analyses# all stages of synthesis and reactor tests were experimentally designed using the design expert software# results revealed that the synthesized catalysts possessed significant ability to perform the ods process such that; 99% conversion during 1 h was achieved using co and nimo(20)/rgo catalyst#
