| Abstract: | A series of pitches were prepared by thermal treatment of petroleum feedstock under oxidative and non-oxidative conditions
at 350-450°C, to study transformation behavior of feed components. Influence of type of oxidizing gas and oxidizing agent on
softening point (SP), coking value (CV), quinoline insolubles (QI) and toluene insolubles (TI) was studied. Rate of increase of
SP of pitch has been found more in oxidative conditions than in non-oxidative conditions. Oxidative conditions may also lead
to reduction in stabilization period for making carbon fibers and activated carbon spheres. Formation of TI/QI is more under
air/oxygen purging as compared to nitrogen purging. |
