Reaction of limestone with nitric acid - affecting factors

Popis výsledku v původním jazyce

The limestone and nitric acid reaction has substantial utilization in industrial practice, notably in calcium nitrate-based fertilizers production. This dissolving process falls into group of heterogeneous non-catalyzed reactions. The aim of this work was to measure, at the chosen reaction conditions and using a continuous monitoring method for fast reactions, the affecting factors and thereafter to try to clarify the significances of various partial processes on the reaction. The experiments took placein the semi-batch isothermal agitated reactor with monofractions of limestone particles at quasi-constant concentration of nitric acid, which was maintained by concentrated nitric acid addition controlled by continuous specific solution conductance monitoring. A pure nitric acid and high quality limestone monofractions from ?Čertovy schody? (CZ) locality were used for the experiments. The kinetics study was focused on dissolution of limestone in diluted solutions of nitric acid at diffe
