Mohsen Yazdani

Mohsen has been born on 11th April 1987at Arak. After his preliminary educations at this city, he entered Sahand University of technology for academic studies of chemical engineering in 2007. He passed his B.Sc. program in this field (Petrochemical Engineering). His final project of B.Sc. was “Evaluation of Direct Conversion of Methanol to Olefins (MTO)’’. He continued master of science degree at Sahand University of Technology in advanced chemical engineering field in 2011. At the moment he is one member of SAPO group under supervision of Dr. Haghighi.

Thesis title:           Synthesis of Nanostructured ZnSAPO-34 Catalyst via Stirred-Hydrothermal Method used for Methanol to Olefins Conversion
Supervisor:           
Dr. Mohammad Haghighi
Thesis abstract:

The methanol to light olefins (MTO) process is one of the most important processes for creating added value. The best catalyst used in this process is the catalyst from Silicoaluminophosphates family that abbreviately named SAPO-34. Enhancement of conversion, selectivity and stability of SAPO-34 catalyst in the MTO process is one of the most important challenges facing for this catalyst. The new generation of catalysts is produced by employing of nanotechnology in their synthesis which mainly leads to reduction of particle sizes, increasing of surface area, increasing of catalytic activity and stability, enhancement of efficiency and productivity, increasing the selectivity and ultimately compaction of industrial units. A small pore SAPO-34 with chabazite structure (CHA) and hole diameter about 0.38 nm has attracted a great attention in past years. Due to acidic strength, proper pore size and regular pore structure in molecular scale, SAPO-34 molecular sieves have high selectivity and conversion with the least amount of by-products in the conversion of methanol to light olefins. In this study, in order to optimize acidity of nanostructured SAPO-34 catalyst, it has been tried to incorporate Zn into its framework. In addition, in order to control the properties and performance of these catalysts, the effect of mixing during crystallization process on hydrothermal crystallization process and properties of products in synthesis of ZnAPSO-34 nanostructured catalyst investigated.

Characterization of synthesized catalysts accomplished by XRD, FESEM, FTIR, EDX and BET analysis. Also, this catalyst assessed in the conversion of methanol to light olefins in order to reach the appropriate conversion and selectivity and long life time. XRD analysis of all samples confirmed the successful synthesis of the samples. The synthesized catalyst particle size was very small. Initially, enhancement of mixing rate led to reduce the particle size while more mixing rate, increased the particle size. The performance of the catalysts in MTO process showed that they have very high conversion. The mixing led to improve product quality in this process. However, increasing the crystallization time, resulted in an increase in the particle size and with further increasing of time, the particle size was reduced. This catalyst also has a very high conversion in the MTO process. It was observed that increasing of synthesis time led to increasing of selectivity in the MTO process.
