摘要

The hydrogen absorption properties of slurries composed of La_(1.8)Ca_(0.2)Mg_(17-x)Ni_x alloy powder suspended in liquid C_6H_6 were investigated. It is found that the La_(1.8)Ca_(0.2)Mg_(14)Ni_3 in benzene liquid has similar hydrogen absorption properties as that of the hydrogen-alloy (gas-solid) reaction and the alloy has a strong catalytic effect on hydrogenation reaction of C_6H_6. The amount of hydrogen absorbed and the hydriding kinetics are related to the temperature, the solid/liquid weight ratio and the surface catalytic activity of the alloy. When the temperature of the slurry is approx 473 K, it acquires a good hydriding rate. The hydrogen absorption capacity of the slurry system composed of 50 wt. percent La_(1.8)Ca_(0.2)Mg_(14)Ni_3 alloy and 50 wt. percent C_6H_6 reaches 5.5 wt. percent of hydrogen at 483 K and 4.5 MPa in 240 min. Results of XRD, XPS and SEM analysis on the crystal structure, surface structure and configuration of the alloy correlated with its catalytic activity are reported and discussed.
