From: Crystal growth of clathrate hydrate formed with H2 + CO2 mixed gas and tetrahydropyran

Sequential images of H2 + CO2 + THP hydrate growing in the liquid bulk at Tex = 282.0 K, ΔTsub = 5.1 K, P = 5.30 MPa. The gas composition was H2:CO2 = 0.55:0.45 in mole fraction. The elapsed time after the hydrate nucleation is indicated below each image.
