Microporous organic polymers for methane storage

Methane storage is important for the development of alternative energy carriers. The synthesis and methane storage properties of microporous hypercrosslinked organic polymers are reported. The figure shows a simulation of methane sorption in microporous hypercrosslinked poly(p-dichloroxylene); up to 5.2 mmol g(-1]) CH4 at 20 bar/298 K; isosteric heat of sorption similar to 21 kJ mol(-1).
