Novel Strategies for the Synthesis of Methane Adsorbents with Controlled Porosityand High Surface Area. Annual Report, January 1, 1994-December 31, 1995

摘要

Natural gas is an attractive alternative to gasoline as fuel for cars because ofits 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.
