活性炭对THF水合物储氢特性影响的实验研究

该实验利用高压水合物实验研究装置,在恒容条件下,研究了温度为1℃、压力分别为6.4 MPa、7.4MPa和8.4 MPa、四氢呋喃(简称THF)摩尔浓度为5.0％时,活性炭对THF水合物储氢特性的影响.研究结果表明,不加活性炭时的平均诱导时间为333 min,加活性炭时的平均诱导时间为250 min,所以活性炭可以在高...

Experimental Research on Activated Carbon's Influence To The Hydrogen Storage Characteristics of THF Hydrates

The influence of activated carbon to the hydrogen storage characteristics of tetrahydrofuran（abbr.THF） hydrates using a high pressure stirring gas hydrate experimental apparatus in constant volume under the temperature of 1℃,pressure of 6.4MPa,7.4 MPa and 8.4 MPa,and the THF solution mole concentration of 5.0%.The results showed that when without adding activated carbon,the average induction time is 333min,and when adding activated carbon,the average induction time is 250min,so adding activated carbon can decrease the induction time at high pressure;when without adding activated carbon,the pressure drop are 0.028 MPa,0.035 MPa,0.040 MPa respectively,and when adding activated carbon,the pressure drop are 0.030 MPa,0.040 MPa,0.090 MPa respectively,so adding activated carbon can improve the pressure drop,and the higher the pressure,the larger the pressure drop;when without adding activated carbon,the hydrogen storage capacity by weight are 0.0026%,0.0033%,0.0031% respectively,and when adding activated carbon,the hydrogen storage capacity by weight are 0.0041%,0.0048%,0.0082% respectively,so adding activated carbon can improve the hydrogen storage capacity by weight,and the higher the pressure,the larger the hydrogen storage capacity by weight.
