摘要
以超高比表面积活性炭为吸附剂,对天然气的吸附储存性能进行了研究。结果表明,超高比表面积活性炭具有较强的循环使用性能,经180次循环使用后,吸附储存天然气的能力仅下降9%左右。天然气的脱附量(V/mL)与脱附时间(t/s)之间满足函数关系:V=149.7Ln(t)-97.2,天然气脱附速率为:dV/dt=149.7/t;吸附压力P(MPa)与天然气脱附量增加百分率X(%)之间满足乘幂函数关系:X=C×P-n。
Natural gas adsorption storage properties of a super-high specific surface area activated carbon were studied. The results showed that this activated carbon had good cycle performance. The natural gas storage ability only decreased 9 percent after 180 times recycle use. The relationship between natural gas desorption amount and time met the equation： V=149.7Ln （0-97.2, and the desorption velocity differential equation was dVIdt=149,7/t. The natural gas desorption amount and pressure complied with the equation： X=C×P^n
