Natural gas is an attractive fuel for vehicles because it is a relatively clean burning fuel compared with gasoline. Here we report the development of natural gas storage monoliths. The monolith manufacture and activation methods are reported along with pore structure characterization data. Gas storage monoliths were fabricated from isotropic pitch-derived carbon fibers (Carboflex fibers, Anshan East Asia Carbon Company), and a powdered phenolic resin (Durez grade 7716, Occidental Chemical Corp). The monoliths were hot-pressed to densities in the range 0.7-1.1 g/cm3, and carbonized prior to activation in a CO2 atmosphere to the desired burn-off. A storage capacity of >150 V/V at 500 psi and 23 deg C has been attained, which is comparable to the best commercially available gas storage carbons. The optimum storage monolith is one which exhibits high methane activity (which is a function of micropore size and total micropore volume) and high density. Such a monolith might be expected to store as much as 180 V/V of methane at 500 psi.
