Abstract
The microporous carbon adsorbent with the specific micropore volume W0 = 0.80 cm3 g−1, micropore width X0 = 1.32 nm, and specific surface area SBET = 2115 m2 g−1 was synthesized by the thermochemical activation method from the carbonizate of nutshell Macadamia in the presence of orthophosphoric acid at 1173 K. At 303 K and 20 MPa, the adsorption capacity of the adsorbent to methane reaches ∼22 wt.%. The volume density of adsorbed methane on the compacted carbon adsorbent with the binder at a pressure of 10 MPa was found to be ~200 nm3 m−3.*
