Monolithic Natural Gas Storage Delivery System Based on Sorbents

摘要

The invention provides methods for producing a strong, light, sorbent-based storage/dispenser system for gases and fuels. The system comprises a porous monolithic material with an adherent strong impervious skin that is capable of storing a gas under pressure in a safe and usable manner.

主权项

1. A gas storage and delivery device comprising a porous gas sorbent monolith contained within an adherent skin, wherein:
the skin is impervious to the gas at >35 atm and comprises a port providing a fluid connection between the monolith and a gas charge/discharge manifold; and the monolith comprises properties: (a) a surface area of >100 m2/g; (b) a density of 0.5 g/cc; (c) interconnected pores with some hierarchical structure and of typical diameter larger than 0.5 and smaller than 1.5 nm; (d) tensile modulus>2 Mpsi, tensile strength>1 kpsi and flexural strength>2 kpsi; and (e) chemical stability in that it does not degrade, or is not significantly attacked by species present, in a gas that is natural gas, hydrogen or CO2.
