Ecology and Chemical Engineering

Engineering and implementing of new nonchemical and nonwaste approach of photocatalytic degradation of organic pollutants resistant to oxidation

• Regulating the properties of the earlier produced catalysts for phenol and cyanides degradation;
• The catalyst should interreact only with certain pollutants, and other present production impurities should not impede the main process of degradation;
• Studying the kinetics of photodegradation, the kinetics of sedimentation of the catalyst pellets, elaborating a mathematical model of the processes of water treatment and removal of the catalyst grains, theoretical and experimental revealing of the optimal working characteristics of the pellets;
• Computing and engineering the design of and producing a pilot water treatment installation as per the requirements of PJSC Magnitogorsk Iron & Steel Works;
• Elaborating the method for modifying the surface of photocatalysts to attain the required properties to them (catalytic activity, selectiveness with regard to certain pollutants, etc.);
• Developing a line-up of catalysts the properties of which are tailored for certain productions;
• Attracting new industrial partners;
• Creating a high-technology enterprise for catalysts production
