strategy. Thermogravimetric analysis(TGA) was used to follow up the various thermal events involved in the decomposition process. Dehydration completes approximately at 150℃, which is followed......
was investigated by TGDSC,XRD and FI-IR.The thermal decomposition process consists of two stages:the dehydration of rare earth hydroxide and alkaline rare earth sulfate within 900 ℃ and the thermal......
effective separation of gallium from aluminum because of a simultaneous increase in the complexion of aluminum with fluoride and a change in the electrical charge of the aluminum . The dehydration model...,chelation, hydrogen bonding, dehydration, This model was expressed as [9] (4) where is concentration of ions......

, as the temperature rose up to 300~323K, LiOH·H2O dehydrated its crystal water, and both the dehydrated and reaction-generated water were evaporated from solid reactant. For the dehydration rate increased......
atmosphere. The temperature of furnace was increased from 298 K to 1 473 K at 10 K/min. The results show that the spent catalyst has three fast agravic steps: dehydration, decomposition of zinc acetate......
show that the pyrolysis process undergoes three periods, i.e. fuel dehydration, volatilization releasing and combustion, the combustion of coke. The main mass loss phase is the volatilization......
that the FeC2O4·2H2O, CoC2O4·2H2O and CuC2O4·nH2O are the main phases. The DSC curves show that two endothermic peaks exit in the heating process, which correspond to the crystal water dehydration......
with it in iron ore concentrate pellets growing area. The properties of fibrosis bentonite and its performance in iron ore pelletizing were studied. The results show that the dehydration rate of fibrosis bentonite...水时间对膨润土含水率的影响 Fig. 1 Influence of dehydration time on moisture content of bentonite 图2 脱水时间对膨润土累积脱水率的影响 Fig. 2 Influence of dehydration time on bentonite cumulative dehydration rate......
, H2O-2-butanol and H2O-MeTHF allowed the glucose dehydration process to achieve HMF yields of up to 61%, 59%, and 50%, respectively. Moreover, in the three biphasic systems, the H-ZSM-5 catalyst was also... the Lewis acid catalyzed isomerization to form fructose and subsequently dehydration in the presence of Brnsted acid to produce HMF [8, 9]. In view of this conversion route, a great deal of effort has......
