Patent ID: 8282714

Claim:
A fluid storage and dispensing apparatus, comprising a fluid storage and dispensing vessel with an interior volume in which is disposed an array of articles of pyrolyzed polyvinylidene chloride carbon monolith adsorbent, wherein the articles of pyrolyzed polyvinylidene chloride carbon monolith adsorbent occupies from 75% to 95% of the interior volume, and the adsorbent has (i) a bulk density of from 0.80 to 2.0 g per cubic centimeter of adsorbent, (ii) a fill density measured for arsine gas at 25° C. and pressure of 650 torr that is greater than 400 g arsine per liter of adsorbent, and (iii) porosity, at least 80% of which is constituted by pores with diameter<2 nm, and at least 60% of which is constituted by pores having size in a range of from 0.3 to 0.72 nm.
