摘要
以Raney-Ni为催化剂,对乙基咔唑在高压反应釜中的循环吸放氢过程进行了研究。研究表明:在6 h内,乙基咔唑实现了在较低温度下的储放氢过程,质量储氢密度达到5.61%,目的在于实现乙基咔唑-十二氢乙基咔唑体系在较低温度下的循环储放氢过程,有效推进有机液体氢化物储氢的实用化进程。
As a new hydrogen storage material,N-ethylcarbazole has potentially interesting prospects in hydrogen storage area because of its reversible hydrogen sorption properties at lower temperature.The cyclic sorption-desorption of hydrogen with N-ethylcarbazole over Raney-Ni catalyst was studied in a high pressure batch reactor.The results show that hydrogen absorption and desorption can carry out at low temperature within 6 h.The gravimetric storage capacity of H2 can reach 5.61%,thus approaching the target of realizing the cyclic sorption-desorption of hydrogen of N-ethylcarbazole-dodecahydro-N-ethylcarbazole system at lower temperature,and effectively advancing the practical process of hydrogen storage material.
