Title: Monolithic natural gas storage delivery system based on sorbents

Abstract

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.

  • A method of storing and subsequently delivering arsine is described, which comprises the steps of: (a) contacting arsine at a temperature of between about -30/sup 0/C and about +30/sup 0/C with a zeolite having a pore size of between about 5 and about 15 angstroms to provide arsine-adsorbed zeolite suitable to be stored, and (b) heating the arsine-adsorbed zeolite to an elevated temperature of no greater than about 175/sup 0/C for a time sufficient to release at least a portion of the adsorbed arsine to provide free arsine.
  • Systems and methods for electrical swing natural gas adsorption are described. An apparatus includes a pressure vessel; an electrically conductive gas adsorptive material located within the pressure vessel; and an electric power supply electrically connected to said adsorptive material. The adsorptive material can be a carbon fiber composite molecular sieve (CFCMS). The systems and methods provide advantages in that both a high energy density and a high ratio of delivered to stored gas are provided.

  • A method for separating gases or other fluids involves placing a magnetic field on a monolithic carbon fiber composite sorption material to more preferentially attract certain gases or other fluids to the sorption material to which a magnetic field is applied. This technique may be combined with the known "pressure swing adsorption" technique utilizing the same sorption material.
