Abstract In order to apply lithium hydroxide (LiOH) as a low temperature chemical heat storage material, the carbonation reaction of LiOH and the prevention method are focused in this research. The carbonation of raw LiOH at storage and hydration condition is experimentally investigated. The results show that the carbonation reaction of LiOH with carbon dioxide (CO₂) is confirmed during the hydration reaction. The carbonation of LiOH can be easily carried out with CO₂ at room temperature and humidity. LiOH can be carbonated at a humidity range of 10% to 20%, a normal humidity region that air can easily be reached. Furthermore,… More >

Abstract The main principles of the technological realisation of the furfural obtaining process have been formulated by Ricard [1]. Based on his recommendations, all investigators proceeded from the assumption that the depolymerisation of pentosans and the dehydration of pentoses in the one-step production of furfural from raw plant material must be accelerated with diluted catalyst solutions. According to this theory, uniform impregnation of the raw material with a catalyst solution is considered necessary. The reduction in the amount of the catalyst solution down to 30–40% of the mass of the dry raw material, suggested by Miner et al. [2], made the… More >
