Abstract

In situ small angle neutron scattering (SANS) has been performed on three carbons, which adsorb methane, and a zeolite, which does not adsorb methane, loaded with CD4 at pressures of 0, 0.4 and 0.8 MPa. SANS is sensitive to CD4 adsorption. The change in the shape of the scattering patterns can be interpreted by an increase in methane density within the pores and the change of the scattering curves at high q suggests that the density of the adsorbed CD4 depended upon the local pore size. Estimates of the adsorbed density were in broad agreement with previous theoretical studies.
