The gaseous hydrogen absorption and desorption... and desorption kinetics of the alloys. Furthermore,varying milling time has an obvious effect on the hydrogen storage properties of the alloys. Hydrogen absorption saturation ratio(Ra10; a ratio......
simultaneously with ammonia solution can reduce the cost of flue gas purification, the decomposition of the rich solution was studied to find out the desorption character. The results show that the high concentration of ammonium sulfate in the rich solution restrains the CO2 desorption. Compared to the desorption rate of ammonium bicarbonate solution, the desorption rate of the high concentration......

by mechanical milling.Effects of Ni content and milling time on the gaseous hydrogen storage thermodynamics and dynamics of alloys were systematically investigated.The hydrogen desorption properties were studied by Sievert apparatus and a differential scanning calorimeter(DSC).Thermodynamic parameters(△H and ΔS) for the hydrogen absorption and desorption of alloys were calculated by Van’t Hoff......
of element of REM with the lowest affinity. Researches on REM desorption in dynamic conditions from investigated ion exchange resins by solution of 1.7 mol·L-1HNO3 and 8.0 mol·L-1NH4NO3 with 0.2 mol·L-1 HNO3 passing were carried out. It was identified that using desorption solution based on ammonium nitrate allows to achieve acceptable recovery degree of REM from the resin. The possibility......
">The isothermal desorption kinetics of the 1.1Mg H2-2Li NH2-0.1Li BH4 system were improved by addition of La Ni4.5Mn0.5alloy. The hydrogen desorption peak temperature of the sample containing La Ni4.5Mn0.5 reduced by approximately 5 K and the activation energy reduced by 9%. The results of isothermal dehydrogenation kinetics analysis implied that the isothermal desorption process at initial stage......
