Abstract


Adsorption of methane with co-adsorption of water, benzene and dichloromethane onto silica  Si‑40 undergoing hydrothermal treatment  using low-temperature 1Н NMR spectroscopy method (200–280 K) under isobaric conditions was investigated. Unusual dependence adsorption vs temperature explained by Van der Waals complexes forming was found.
