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 cm.sup.3 /g; (b) a specific mesopore volume equal to or greater than 0.5 cm.sup.3 /g; (c) a bulk density equal to or greater than 0.25 g/cm.sup.3 ; and (d) a surface area per volume equal to or greater than 400 m.sup.2 /cm.sup.3. 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 cm.sup.3 /g, but the sum of the specific mesopore volume and the specific micropore volume should always be equal to or greater than 1.0 cm.sup.3 /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 adsorbent is typically in a free-flowing or monolithic form.
