Research of the effect of desicants on moisture adsorption
 Němec, Mojmír ; Lisá, Hana (referee) ; Elbl, Patrik (advisor)
Desiccants are special materials that can effectively adsorb moisture from the surrounding air or space. Desiccants such as silica gel or molecular sieve are often used in laboratory applications, for example to determine the properties of solid fuels. The introduction of the research section is devoted to the description of these properties. The thesis then describes the methods used to accurately determine the moisture in solid fuels. The main part of the thesis is devoted to desiccators together with desiccants, which form a significant part in the process of determining moisture in solid fuels. The experimental part deals with the investi-gation of the effect of different desiccants on the rate of air moisture depletion in the desic-cator under laboratory conditions. The moisture loss in the desiccator is measured using the SHT4x Smart Gadget, which is placed in the desiccator together with the desiccant. The out-put of the experimental measurements are the moisture uptake rate curves of different desic-cants for desiccant weights of 50 g, 100 g, 150 g, 200 g and 250 g. At the end of the thesis, the measured curves of the different desiccants are compared with each other in terms of efficiency.
