The influence of oil bitumen additives to charcoals, obtained by the pyrolysis of the extracted larch bark on the properties of the active carbons was studied. It was shown that the  increase of the amount of bitumen in the charcoal reduces their sorption activity on iodine and rises their abrasion resistance. It was found that after  the impregnation of raw charcoal by 10% solution of  bitumen in toluene the sorption activity of activated carbon on iodine reaches 73% and their abrasion resistance is more  than 90%.
