Abstract:
1. A process for separating CH 4 from a process feedstream, comprising: a) contacting an adsorbent material comprised of a zeolitic imidazolate framework material with a process feedstream comprising CH b) adsorbing at least a portion of the C c) producing a CH wherein the zeolitic imidazolate framework material has a framework structure wherein each vertex of the framework structure is comprised of a single metal ion and each pair of connected adjacent vertices of the framework structure is linked by nitrogen atoms of an imidazolate anion or its derivative, and wherein the zeolitic imidazolate framework material has an adsorptive loading ratio measured at 301 K and 106.6 kPa for the C
