oxidative desulfurization of petroleum products using oxidized cobalt oxide on the surface-modified carbon nanotubes

Due to the dangerous effects of sulfur in hydrocarbon compounds and its impact on environmental health, a new formulation based on surface-modified carbon nanotubes and a cobalt oxide has been prepared# oxidative desulfurization was the main reaction of this process that was utilized to reduce this impurity# after the preparation of this nanocatalyst, the tem images and thermogravimetric analysis were studied to evaluate the structure of this complex# the results show that the combination of metal oxide and functionalized nanoparticles presents better efficiency in sulfur removal# in addition, the reaction rate raised by increasing the number of functional groups on the surface of nanotubes# the influence of temperature, reaction time and the amount of oxidizing agent in the sample was investigated# the results show that high temperature and high amount of oxidizing agents increase the oxidation efficiency# this phenomena also enhance the efficiency of desulfurization# this finding can be more effective in sulfur removal of hydrocarbons in oil, gas, and petrochemical industries#
