METHOD AND VESSEL FOR THE STORAGE OF GAS |
摘要 |
Acetylene is stored at elevated pressure by charging with acetylene at elevated pressure a pressure vessel (typically a gas cylinder) containing carbonaceous adsorbent able reversibly to adsorb acetylene. The adsorbent has: a) a specific micropore volume equal to or greater than 0.5 cm3/g; b) a specific mesopore volume equal to or greater than 0.5 cm3/g; c) a bulk density equal to or greater than 0.25 g/cm3; and d) a surface area per volume equal to or greater than 400 m2/cm3. Alternatively or in addition to (a) and (b) above the specific volume of pores having a diameter in the range of 1.5 to 3.0 nm is equal to or greater than 0.3 cm3/g, but the sum of the specific mesopore volume and the specific micropore volume should always be equal to or greater than 1.0 cm3/g. Preferably, at least 75 % of the specific mesopore volume is contributed by mesopores having a diameter in the range of 2 to 5 nm and at least 90 % of the micropores have a diameter of at least 0.4 nm. The absorbent is typically in a free flowing or monolithic form.
