Abstract

Clathrate hydrates of N₂ and CO₂ were investigated in situ as a function of gas pressure by neutron powder diffraction. Gas pressure cells developed specifically for this work were employed. The pressure dependency of the filling of the different cages in these clathrate hydrates was established. In contrast to some earlier indirect evidence the small cages in CO₂ clathrate hydrate are partly filled, however the generally accepted Langmuir-behaviour of the filling is violated in this case. Likewise, instead of the usually assumed filling of the large cages with only one N₂ molecule a double occupancy of these cages is observed for N₂ clathrate hydrate.
