Heterogeneous non-catalysed reactions

Characteristic of the working group Heterogeneous non-catalysed rections:

As the name implies, our working group deals with the study of solid - liquid or solid - gas reactions respectively. These reactions often play key role in field of industrial chemistry, energetics, metallurgy and/or ecology. We are more focused on applied research, which especially involves the kinetics study of reactions important in the production of mineral fertilizers and processes for environmental protection.
