Defluorination of C9 petroleum resin was carried out over noble metal and metal oxide catalysts with fixed-bed reactor. Under hydrogen atmosphere, Pt-alumina catalyst decomposed 60% of fluorine compounds at 225°C. Under nitrogen atmosphere, titania catalyst showed higher activity(70%) without the decomposition of petroleum resin.
