    Bitumen production via tar oxidation in the presence of petroleum resin with fluorine-containing groups
    (Publishing House of Lviv Polytechnic National University, 2010) Bratychak, Michael; Chervinskyy, Taras; Astakhova, Olena; Shyshchak, Olena
    The tar oxidation process has been studied at 523 K, air flow rate of 2.0; 2.5 and 5.0 h-1 and process time of 6, 9 and 12 h in the presence of 2.5; 5.0 and 7.5 mas % (to calculate for the raw material)of petroleum resin with fluorine atoms. The tar is the residue of black oil vacuum distillation obtained fromthe oils of Western-Ukrainianfields. The effect of process conditions on the characteristics of obtained bitumen has been determined. The structural-group composition of blown bitumen has been examined. Вивчено при 523 К, витраті повітря 2,0; 2,5; 3,0 год-1 та тривалості 6, 9 і 12 год. процесс окиснення гудрону, який являє собою залишок вакуумної перегонки мазута, виділений з нафт західно-українських родовищ, в присутності 2,5; 5,0; 7,5% мас. на вихідну сировину нафтополімерної смоли, що містить атоми флуору. Встановлено вплив умов проведення процесу на характеристику модифікованих бітумів та вивчений структурно-груповий склад окиснених бітумів.
