Abstract

ETS-10 type materials preferentially adsorb ethane and, if present, C3+ paraffins from mixtures comprising methane, ethane and optionally C3+ paraffins at pressures above 200 psia. A process in which ETS-10 type materials are used to separate ethane and C3+ paraffins from natural gas streams at over 200 psia is provided.
