【摘要】 将Ru/γ-Al2O3和Pd/γ-Al2O3混合后,对乙基咔唑在高压釜中的可逆储放氢过程进行研究。研究表明:在433 K下,乙基咔唑在30 min内完成储氢过程,质量储氢密度达到5.67%,体积储氢密度为52.17 kg/m3,且在473 K下可实现加氢产物很好地脱氢,乙基咔唑表现出较好的循环效果。更多还原

【Abstract】 N-ethylcarbazole is considered as a promising material with a theoretical gravimetric and volumetric storagecapacity of 5.80% and 53.51 kg/m3,respectively, because of its reversible hydrogen uptake-release property at lowertemperature. The cyclic absorption- desorption of hydrogen with N- ethylcarbazole was discussed over the mixture ofPd/γ-Al2O3 and Ru/γ-Al2O3 in the autoclave. The results show that hydrogen absorption can carry out at 433 K within 30 minutes,the gravimetric storage capacity of H2 can reach 5.67%, the volumetric hydrogen storage density can achieve 52.17 kg/m3,and the hydrogen in hydrogenation product can be released effectively at 473 K.更多还原
