Results and discussion 3.1 Hydriding and dehydriding properties A comparison of the hydrogen absorption- desorption between the samples doped with 10% MF3 (M=Ti, Fe) and the undoped samples prepared...- dehydriding processes of the MF3-doped composites, making catalytic effect on the hydrogen absorption- desorption of MgH2. Besides, from the Kissinger’s plot, the values of the apparent activation energies......

The apparent activation energy of the hydrogen absorption reaction of MlNi5-toluene...Kinetics of Liquid-Phase Hydrogenation of Toluene Catalyzed by Hydrogen Storage Alloy MlNi5 徐国华1,安越1,陈长聘1,袁华军1 (1.College of Materials Science & Chemical Engineering, Zhejiang University, Hangzhou......
milling would become more slantwise. Under the 2.02×105Pa H2 at the same temperature, the thermodynamic hydrogen absorption content can be even lower than that of hydrogen storage alloy without ball milling. Such low hydrogen absorption capability results in fewer activated atomic hydrogen in the surface and low catalytic activities. Since the anode is in protection of reductant H2 during the working......
: Hydrogen storage properties of LaN4.25Al0.75 alloy were experimentally investigated by XRD, PC isotherm curves, hydrogen absorption kinetics curves, XPS and its particle diameter. The structure of unit... rapid hydrogen absorption rate and good resistance to combustibility. It is also found that the function of the hydrogen absorption plateau pressure and temperature is ln peq=-4 820/T+12.46......
. Pressure-composition-temperature(PCT) curves of the alloys were determined by electrochemical methods[6]. The thermodynamics parameters including the equilibrium pressure of the hydrogen absorption...-composition-temperature(P-C-T) curves measured at 20, -20 and -40 ℃ are shown in Fig.4. The equilibrium pressure of hydrogen absorption or desorption (Peq) are defined as following equation[7]: ......
Dynamics of liquid-phase catalytic oxidation of hydrogen sulfide removal in rural biogasJIA Li-juan(贾丽娟), NING Ping(宁平), WANG Xiang-yu(王向宇), QU Guang-fei(瞿广飞), XIONG Xiang-feng(熊向锋) (Faculty of Environmental Science & Engineering, Kunming University of Science & Technology,Kunming 650500, China)Abstract:Hydrogen sulfide in rural biogas was removed with liquid-phase catalytic oxidation......
) clearly enhanced the hydrogen absorption capacity of the melt-spun nanocrystalline/amorphous Mg75Ni20Mm5 alloy. Based on the above-mentioned literatures, it is apparently reasonable to postulate that additive La is beneficial for enhancing the glass forming ability and the hydrogen absorption capacity of the Mg2Ni-type alloy as La has the biggest atomic radius among all rare earth elements......
using quantitative energy dispersive X-ray spectroscope (EDS). Hydrogen sorption properties of the samples, with a typical amount of about 1 g, were examined by a Sieverts-type apparatus. Absorption... gas and the ideal gas. Fig.2 shows the hydrogen absorption amount of both 3MFH and 3MFHT mixtures with the corresponding ball milling time. It can be seen that the amount of hydrogen absorption......
