In this work, carbon nanospheres (CNSs) were prepared by carbonizing core/shell particles of polymethylmethacrylate (PMMA)/ resorcinol formaldehyde, polystyrene (PS) waste and palm tree (PT) leaves using standardard methods. Scanning electron microscopy (SEM), energy-dispersive X-ray spectrometer (EDX), Raman and Fourier transform infrared (FTIR) were used for characterization of the resulting carbon nanospheres. Investigation of desulfurization capabilities of the various sorbents prepared was carried out using model diesel; thiophene (T), benzothiophene (BT) and dibenzothiophene (DBT) and removal of these organosulfur compounds was found to be in the order; DBT ˃BT ˃ T with the aid of GC-SCD . The sorbents from wastes (PS and PT leaves) compare favourably well with the one from the optimum source (PMMA). The sorbents produced are highly regenerable.
