Název v původním jazyce

Absorption of pressurized methane in normal and supercooled p-xylene revealed via high-resolution neutron imaging

Popis výsledku v původním jazyce

Supercooling of liquids leads to peculiarities which are scarcely studied under high-pressureconditions. Here, we report the surface tension, solubility, diffusivity, and partial molar volume fornormal and supercooled liquid solutions of methane with p-xylene. Liquid bodies of perdeuteratedp-xylene (p-C8D10), and, for comparison, o-xylene (o-C8D10), were exposed to pressurized methane(CH4, up to 101 bar) at temperatures ranging 7.0–30.0 °C and observed at high spatial resolution(pixel size 20.3 μm) using a non-tactile neutron imaging method. Supercooling led to the increaseof diffusivity and partial molar volume of methane. Solubility and surface tension were insensitiveto supercooling, the latter substantially depended on methane pressure. Overall, neutron imagingenabled to reveal and quantify multiple phenomena occurring in supercooled liquid p-xylene solutionsof methane under pressures relevant to the freeze-out in the production of liquefied natural gas.
