Název v původním jazyce

Oxidation of coal-based raw materials by nitric acid

Popis výsledku v původním jazyce

The process of oxidation of coal-based raw material in solid phase by nitric acid is described. The procedure was designed so that it can also be realized on a large industrial scale. Two coal raw materials were chosen for this research: coal from the Družba open-cast mine in the Sokolov Coal Basin, and lignite from the mine in Mikulčice belonging to the Vienna Basin. There is a description of the technological parameters of coal-based raw material oxidation by nitric acid as well as an evaluation of the consumption of nitric acid in relation to the amount of organic matter entering the process, and the achieved content of leachable humic substance in the products prepared. Oxidized products were used for the preparation of alkali nitrohumates from which nitrohumic acids were prepared. The chapter presents the chemical and structural parameters of the starting raw materials and the prepared products. The biological activity of the produced potassium nitrohumates was also evaluated.
