    Analysis of the process of obtaining methyl esters of fatty acids from waste vegetable oils
    (Lviv Polytechnic Publishing House, 2015) Kukushkina, Olena; Vasylkevich, Oleksandr; Bondarenko, Sergiy; Beznosyk, Yuriy; Kyiv Politechnic Institute
    The technological features of the process of obtaining the methyl esters of carboxylic acids from renewable materials were analyzed. The results showed that the waste vegetable oil can be used as raw material for biofuels production. However, to increase product yield and its quality technological scheme of obtaining the product correction is needed.

    Modelling of heterogeneous systems in microreactors
    (Lviv Polytechnic Publishing House, 2015) Miroshnychenko, Yuliyia; Beznosyk, Yuriy; National Technical University of Ukraine “Kyiv Polytechnic Institute”
    In this paper an overview of approaches to the modelling of heterogeneous systems (liquid-liquid) in the microreactor was performed, mathematical models of various chemical reactions in microchannels published in the literature was considered and the comparison of theoretical and practical experiments was executed. Based on the generalized data, it has been proved the feasibility of microstructured reactor application for the process of silica surface functionalization in order to carry out the synthesis of innovative sorption materials. The next stage of this research is to develop a mathematical model of the process and its implementation by means of special software environment.

    Modeling of Ni2+ exchange on the strong acid ion-exchange resin and the organic-inorganic ionite
    (Lviv Polytechnic Publishing House, 2015) Afonin, Gennadiyy; Beznosyk, Yuriy; Dzyazko, Yuliyia; National Technical University of Ukraine “Kyiv Polytechnic Institute”; Academy of Sciences
    In dynamic conditions extraction of ions of Ni2+ from the combined solution with using of acid ion-exchange gel pitch and the composite ionite on its basis containing units of nanoparticles of hydrophosphate of zirconium is investigated. The model allowing to define time for which capacity of Ni2+ ions is ful offered. The model assumes use only of empirical parameters reflecting concoction of ions in a firm phase.
