The formation of CO₂ hydrate in this work was experimentally investigated using a high pressure volumetric analyzer (HPVA). The investigations in pure CO₂ gas systems (at 275 K and 36 bar) highlighted the effect of bed height on CO₂ hydrate formation by employing standard silica gel and zeolite 13X as porous mediums. The CO₂ uptake of zeolite 13X saturated with 5.6 mol % tetrahydrofuran and 0.01 mol % sodium dodecyl sulfate (zeolite 13X-5) increased from 0 to 0.58 mmol of CO₂ per g of H₂O when the bed height was reduced from 3 to 2 cm.
