    Ultrasonic activation of the catalysts of ethylbenzene dehydration to styrene
    (Publishing House of Lviv Polytechnic National University, 2012) Zhyznevskiy, Vyacheslav; Gumenetskiy, Volodymyr; Shyshchak, Olena; Tsybukh, Roman
    The ultrasonic treatment of Fe2-Bi-Mo2-Ox catalyst of ethylbenzene oxidative dehydration to styrene has been studied. Its physico-chemical properties have been compared with those of non-activated catalyst before and after operation. It has been shown that the catalyst prepared from salts solution activated by ultrasound has better activity and increases styrene yield under the same conditions. Досліджено ультразвукове оброблення Fe2-Ві-Мо2-Ох каталізатора окиснювального дегідрування етилбензолу в стирол та порівняно його фізико-хімічні властивості з неактивованим каталізатором до і після роботи. Показано, що виготовлений з розчину солей і активований ультразвуком каталізатор має кращу активність та підвищує у порівняльних умовах вихід стиролу.
