Annotatsiya

In this study, waste of hydrogenation catalysts of the “Pricat 9920” grade, used in the conversion of liquid vegetable oils into semi-solid products at IDEAL OIL JSC located in the Namangan region of the Republic of Uzbekistan, was utilized. To analyze the chemical composition of this hydrogenation catalyst waste, an average sample was collected and analyzed using a high-performance energy-dispersive X-ray fluorescence spectrometer equipped with a polarization system - Rigaku NEX CG EDXRF (Japan).
