摘要:

以天然海藻为原料, 通过自活化制备了碳材料SarCW-900-HF及LamCW-900-HF, 并对其进行表征和储甲烷能力测试. 其比表面积分别为812和671 m2/g, 孔体积分别为0.45和0.44 cm3/g, 孔分布的峰值均在1.1 nm, 在室温及3.5 MPa压强下储甲烷的能力分别为272 mg/g(质量比21.3%)和246 mg/g(质量比19.4%), 经20 MPa压强压片后吸附甲烷体积比达到274和449 cm3(STP)/cm3, 超过美国能源部提出的吸附剂的指标[263 cm3(STP)/cm3].

Abstract:

Two types of carbon material were prepared by self-activation using the seaweeds Hizikia fusifarme(Sar) and Laminaria japonica(Lam) as raw materials. The methane storage capacity of SarCW-900-HF and LamCW-900-HF are up to 272 mg/g(mass fraction 21.3%) and 246 mg/g(mass fraction 19.4%) at room temperature and pressure of 3.5 MPa. The specific surface area of the two materials are 812 and 671 m2/g, and pore volume are 0.45 and 0.44 cm3/g, respectively. The peak of pore distribution is at 1.1 nm. After tableting under pressure of 20 MPa, the methane adsorption volume ratio reached 274 and 449 cm3(STP)/cm3, beyond the DOE’s target of 263 cm3(STP)/cm3.

Key words: Hizikia fusifarme(Sar), Laminaria japonica(Lam), Self-activation, High pressure methane storage
