Mohsen has been born at amol, a beautiful city of mazandaran province in Iran. After his preliminary educations at this city, he entered sahand university of technology for academic studies of chemical engineering. He passed his B.Sc. program in this field and in the branch of petrochemical engineering. His final project of B.Sc. program was “modeling of air pollutant dispersion from point sources by using of ISC software’’. Again for his M.Sc. program, he chose sahand to continue his investigative activities in this university and in the field of environmental engineering. At now he is the student of semester 3 and he is conducting research on the environmental catalysts and the removal methods of organic compounds from industrial waste waters. Especially he is working on the synthesizing of a suitable catalyst for the wet air oxidation processes.
Thesis title: Synthesis of Transition Metals over Ceria-Zirconia Nano Catalysts Using Ultrasound Methods and Their Application in the Wet Air Oxidation Process
Supervisor: Dr. Mohammad Haghighi
Co-Supervisor: Somayeh Allahyari
Thesis abstract:
In present study, which was done in Reactor and Catalyst Research Center, catalytic wet air oxidation (CWAO) of aqueous solutions of phenol were carried out under oxygen atmosphere at 160 ºC in a stirred batch reactor by using transition metal (Cu, Ni) oxide catalysts supported by composite oxides (CeO2-ZrO2). The advantages of using the composite oxides are high thermal stability and good oxygen storage capacity. The catalysts were synthesized based on a sonication process. The catalysts were characterized by XRD, SEM, BET and FTIR analyses, and the results show that nanometric copper particles are well distributed on the support surface. The effect of active phase and catalyst loading of Cu/CeO2-ZrO2 and Ni/CeO2-ZrO2 sonochemically prepared catalysts as well as Ce/Zr ratio in Cu/CeO2-ZrO2 catalysts which were synthesized by impregnation method, were studied. With increasing the transition metal content, the phenol conversion is increased. The optimum catalyst loading is 9 gr/lit. Phenol conversion of 100% can be achieved by using Cu(5%) catalyst with 9 gr/lit catalyst loading in solutions with initial phenol concentration of 1000 ppm and after 3 hours of reaction. Despite the high oxygen storage, Cu/CeO2 catalyst is more active than Cu/CeO2-ZrO2 catalyst.
