Methane storage on CPO-27-Ni pellets

The nickel-based metal-organic framework (MOF), referred to as CPO-27-Ni, has been recently proposed as adsorbent for the storage of gaseous fuels. Once an adsorbent has been identified, shaping is an essential step for its industrial implementation. According to that, a study on the influence of shaping on physical-chemical characteristics and CH4 storage properties of CPO-27-Ni was performed. XRD analysis evidenced that tableting till 0.1 GPa slightly modify CPO-27-Ni crystal structure. As a matter of fact, the specific surface area of the compound after tableting was just a little bit lower with respect to the as-synthesised one. Moreover, the tableted MOF exhibited a CH4 specific capacity close to the as-synthesised powder and comparable to medium performing MOFs.
