Activated carbons were prepared by carbonization and steam activation of nitrogen-enriched low-rank coals. N-enrichment was performed by reaction of ammonia or its derivatives (ammonium carbonate, hydrazine, hydroxylamine, urea) with the carboxyl groups either naturally occurring in coal or artificially introduced by performic oxidation. Urea at an elevated temperature and pressure appeared to be...
The effect of addition of the iron graphite intercalation compound (GIC-FeCl 3 ) to coal tar pitch, used as a carbon precursor, on the porosity development in the resulting steam activated chars, was studied. Different conditions of chars preparation have been considered. Benzene (298 K), nitrogen (77 K), carbon dioxide (298 K) and water (298 K) sorption measurements were taken as basis...
