Abstract
The demineralization of semicoke obtained from coals from the Ziddi and Fon-Yagnob deposits in Tajikistan was carried out by treatment with nitric acid. It was found that the ash content of the semicoke can be decreased by a factor of 2–3, as compared with the initial value. The iodine number of enriched semicoke was determined, and it indicated an increase in the adsorption activity.
