  7. Abstract:
  8. Volatile organic materials are amongst the most important air pollutants that presence of the moisture in polluted air during oxidation process are the most difficult to remove volatile contaminants using catalysts. In this study, nano-copper oxide catalyst on nano-alumina for complete oxidation of toluene in the presence of moisture at different temperatures and atmospheric pressure were examined. Alumina basic using co-precipitation and sol-gel methods have been synthesized, which is for the first time that alumina tri-second-butyl pre-manufacturer have been used for gamma-nano-alumina by sole gel method was used. Surface properties of synthesized nano-alumina have been studies by various analysis, and results showed that catalysts with proper distribution and copper oxide crystals smaller than 10 nm based on nano-gamma- alumina in sol-gel method using ethanol solvent was produced. To improve the performance of copper oxide catalyst, copper bimetallic catalysts with lanthanum, cobalt and nickel were made. Structural test results showed that size of the particles in bimetallic catalysts is reduced and better distribution of the copper oxide on nano-gamma-alumina base is seen. Reactor test results of the bimetallic catalysts confirmed the surface characterized and to improve the removal of toluene in the presence of moisture is more effective
