A step towards localizing advanced catalytic technology – | Iranian and world news

Engineer Mohammad Hassan Foghani, Engineer Elnaz Mohammadi Pour and Dr. Sara Tariqi, with the guidance and guidance of Dr. Sajjad Habibzadeh, a member of the Amirkabir University faculty, called “Catalytic Catalytic Production and Correction”.

“The process of producing gasoline in the country depends directly on the strategic catalysts used in the FCC unit,” said Foghani. However, before, there was a significant dependence on the external samples of these catalysts.

He described FCC catalysts as one of the most sophisticated catalysts used in the refinery industry, composed of four main components of zeolite, matrix, filler and binder, and continued: “Operating these catalysts early can cause heavy damage to the refineries and threaten the country’s energy security.”

The researcher noted: During the resuscitation process, the catalyst structure is exposed to three destructive factors including high temperatures, water vapor and the presence of metal pesticides such as vanadium; Factors that lead to the destruction and collapse of its structure. Accordingly, the project focuses on the development of selective metal traps to increase vanadium to increase the resistance and sustainability of the catalysts.

Successful implementation of the project in collaboration with the industry

This research project is implemented in partnership with Amirkabir University of Technology and the first FCC catalyst manufacturer in the Middle East. The results of this project are now used in the company’s manufactured catalysts used in the FCC/RFCC Unit Shazand Arak Refinery and have significantly improved the stability of these catalysts on an industrial scale.

In addition to increasing stability against the harsh conditions of resuscitation, the use of this new technology has reduced the cost of catalyst production and reduced the consumption of rare earth metals; A issue that plays an important role in reducing the country’s value.

“In the first phase, comprehensive studies based on scientific articles and patents to identify the catalyst destruction mechanism, then using a new structure based on Proskite, were designed and synthesized to selectively attracted and synthesized,” said Elnaz Mohammadi Pour, a researcher at the project. It was developed in the laboratories of Knowledge Based Company and the Faculty of Chemical Engineering of Amirkabir University of Technology and was put into the FCC catalyst composition after optimization.

He said that the performance of the new catalyst was evaluated in simulated conditions with the industrial environment, adding that the results showed significant improvement over the previous samples. The findings of this study are published in the accredited Fuel Journal (Q1 rank and effect coefficient of 6.7).

Mohammadi Pour said one of the most sophisticated parts of the project was to optimize the formulation and control of the final catalyst properties, and continued: The high cost of performance tests was one of the economic challenges of the project, which was possible with the financial support of the chemical knowledge company.

One of the competitive advantages of the project was a significant increase in stability, activity and catalytic selection, high capacity to attract vanadium pollutants and increase gasoline production efficiency by up to 5 % and noted: The results of this study can be used in the oil refining industry, especially in quality gasoline production. Also, given the success of the prosecite structure in increasing the stability of the catalyst, the next phase of the project will be to reduce the amount of rare earth metals in the catalyst formulation.

Mohammadi Pour added: “The project, which has been completed over a two -year period, has no similar internal sample and its production technical knowledge is currently only available to renowned companies such as Basf and Grace.

According to him; The FCC Catalyst Production and Modification Project aims to eliminate feed pollutants “is not only an important step in localizing the country’s advanced catalytic technology, but it can pave the way for the production of other strategic refinery catalysts and contribute to the savings of foreign currency and promotion of indigenous technology.
