Thesis title:           Synthesis of Nanostructured Pt/Clinoptilolite-CeO2 catalysts using Acid Treatment and Precipitation-Ultrasound Methods

Thesis abstract:

Due to the wide spread of environment pollutions, it has been of great importance to eliminate these pollutants. Toluene, as the most important aromatics and the most used substance in chemical and petrochemical industry, is one of the major contributors to air pollution. Due to this fact that chemical industries are one of the major parts of Iran's industry, several methods of toluene removal have been studied. Owing to several profits that catalytic processes have, this technology has been chosen to eliminate toluene from air. For this reason, the regarding process has been studied in laboratory scale to achieve the effective parameters for its good design. Considering the fact that catalyst is a key factor in process's efficiency, it is of great importance to synthesize catalysts with proper characteristics. Due to the vast usage of natural zeolites, these materials have been used as catalyst support. For modification of their characteristics, they were subject to some acid treatments. Moreover, cerium oxide has attracted much more attention as an effective promoter or supporting material based on its high oxygen-storage, noble metal dispersion, small particle size and increase in the thermal stability. Therefore ceria and Pt-ceria catalysts were synthesized on the acid-treated clinoptilolite and then some of their structural properties were studied (XRD, XRF, FTIR and BET).

Characterization results show that acid treatment destroyed clinoptilolite structure but improved the surface area. Moreover, the addition of ceria resulted in the increase in surface area but it had an amorphous structure, but the XRF results confirmed the existence of cerium oxide in the structure. Additionally, activity tests were carried out in low pressure oxidizing pilots. The results showed the high activity of synthesized nanocatalysts. Furthermore, the addition of ceria to clinoptilolite and increase in its content proved to have positive effect on toluene removal. Moreover, the addition of 1% of Pt to the structure had significant effect on the activity of the catalyst. Besides, the increase in the toluene concentration in feed and also the feed flow rate decreased the efficiency of the process.
