Novel strategies for the synthesis of methane adsorbents with controlled porosity and high surface area. Annual report, January 1, 1994-December 31, 1995
Natural gas is an attractive alternative to gasoline as fuel for cars because of its desirable emission characteristics, good cold starting characteristics, and high octane number. A major factor that limits widespread use of NGV`s is the low energy density of natural gas. The authors have developed low-cost gel precursors that are excellent binders of high surface area carbon and produce monoliths with piece density of 0.64 g/mL, carbon packing density of 0.62 g/mL and methane volumetric storage capacity of 140 V/V (based on volume of gas delivered) at 500 psia. The authors` preliminary experiments show that piece density may be further increased under suitable processing conditions and that even higher methane volumetric capacities will be attainable.
