Applied and Industrial Chemistry
Abstract (en)
This dissertation is part of the research performed within the project
ON 172061. Laboratories used: Laboratory for Applied and industrial
chemistry and Laboratory for organic analysis and synthesis of the
Department of Chemistry of the Faculty of Science and Mathematics
in Nis, Laboratory of the Faculty of Technology in Novi Sad and
Laboratories of the Institute for nuclear sciences "Vinca", University
of Belgrade.
The aim of this doctoral dissertation is chemical synthesis of the
Al2O3-based catalyst in the form of powder. The catalysts were
synthesized by modified (sol-gel, reflux and hydrothermal) method. In
addition, the chemical modification of the catalyst based on Al2O3
was carried out with the selected dopant/modificator (KI). The optimal
conditions for the synthesis, modification and activation of the
catalyst, as well as the selection of precursors for the synthesis of the
catalyst (aluminum-isopropoxide and aluminum-trisecbutoxide), were
examined.
Complete physico-chemical characterization of synthesized catalysts
was performed (analysis of textural, structural, morphological,
thermal and surface properties of catalysts).
The catalysts were tested in the reaction of transesterification of
sunflower oil with methanol.
The influence of a large number of process parameters (reaction
temperature, pressure, velocity and type of mixing, mass fraction of
the catalyst, molar ratio of reactants, influence of co-solvent(s), etc.)
on the reaction yield were studied.
The kinetics of the reaction, the reuse of the catalyst, catalyst
regeneration and the stability of the catalyst were examined.
The physicochemical characteristics of the synthesized catalytic
materials have been correlated to the catalytic activity in the reaction
of transesterification of sunflower oil.
