Successful end of international joint project with the University of Girona, Spain

Dr. Naeimeh Bahri, the project manager, said in this regard: “This project was defined in order to synthesize suitable catalysts for hydrogenation process, one of the most widely used processes in the chemical and petrochemical industries.
Dr. Bahri, faculty member of Polymerization group in IPPI said: “In the present study, three different types of catalysts were investigated by different modifications of the halloysite surface (used as a support) using different nitrogen ligands. First, after designing different ligand structures, the most suitable ligand with the highest Pd adsorption energy have been selected through molecular modeling calculations performed at the University of Girona, Spain, by Dr. Albert Poater. Appropriate ligands were then deposited on the surface of the halloysite. The efficiency of the synthesized catalysts in two important types of hydrogenation reactions in industry, namely hydrogenation of polyalpha-olefin (PAO) oil and nitrobenzene (to produce aniline which has biological and pharmaceutical importance) was investigated.”
She added: “since the catalysts presented in this design are heterogeneous, they can be used for industrial applications, whether in slurry reactors or fixed bed types. Also, because the combination of molecular modeling with experimental work have been used, the best catalysts are designed and synthesized that can be used repeatedly with high efficiency in the intended reactions. Two articles from the present study have been published in the Journal of Colloid and Interface Science and Applied Clay Science, and another article is under review.”
