Abstract:
The effect of chemical treatment (with nitric acid, sodium hydroxide, or superheated steam) of sapropel carbonization products on the properties of the fi nal carbon–mineral materials was studied. Steam activation exerts the strongest effect on the samples of carbon–mineral materials prepared from organic sapropel, leading to the maximal increase in the surface area and to a change in the textural characteristics. All kinds of treatment lead to a considerable increase in the fraction of micropores (to 26% of the total pore volume) and to a decrease in the fraction of macropores (from 44 to 14% of the total pore volume). The strongest changes in the properties of carbon–mineral materials prepared from mineral sapropel are observed upon acid treatment.
