Inflence of Granulation to Sorption Properties of Expanded Graphite
 Hladík, Jakub ; Poláček, Petr (referee) ; Kučera, František (advisor)
Expanded graphite is one of the promising sorption materials, but its disadvantage is difficult handling. This thesis deals with the granulation of expanded graphite and the effect of granulation on oil sorption. Samples with a starch and dextrin binder were prepared. Samples filled with cellulose fibers and wood flour were prepared with a starch binder. The strength of the granulate was determined from the sub-sieve fraction. The sorption capacity was determined gravimetrically after 30 minutes of oil immersion. The granulate filled with a lower amount of wood flour achieved the highest sorption capacity. The addition of cellulose fibers substantially strengthened the granulate. Based on the previous results, a granulate of a defined shape and size was prepared. The morphology of the granulate was observed by scanning electron microscopy.
