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.
