Mesocarbon microbeads (MCMBs) are a valuable carbon material, and the production of this material highly depends on the reaction conditions and feedstock properties. In the present study, supercritical fluid extraction fractionation (SFEF) technology…
After the quinoline insoluble fraction was removed, petroleum pitch (PP) was brominated under ultraviolet light irradiation for 3 to 9 h with a bromine to PP mass ratio of 1:20 to prepare brominated PPs (BPPs). Synthetic pitches (SPs) were produced…
