Hydrothermal treatment can be used for the on-farm processing of lignocellulosic materials this study investigated the hydrothermal treatment of sweet sorghum bagasse (ssb) powder for the extraction of hemicellulose from it. In the experimental treatments, 10-20 g ssb powder was mixed with 80-90 g water to obtain 10, 15 and 20 % (g bagasse/g aqueous mixture) concentrations and the mixture was kept in an autoclave for the hydrothermal treatment at 394 k the autoclave was already saturated with steam and therefore. Hydrothermal techniques have been used for the preparation of thin films of perovskites of the aiibivo3 form experimental in the first set of experiments the substrates were rectangular titanium foils figure 1 schematic experimental set-up for the localized hydrothermal fabrication of thin films.
The goal of this study is to provide a relatively simple experimental protocol for studying mineral effects on hydrothermal organic reactions to demonstrate how to use this approach to study hydrothermal organic-mineral interactions, a simple experiment using a model compound.
