    In this study, regarding the increasing interest on renewable sources of energy as well as considering the challenges of climate changes, the potential of shaped MOF MIL-160 (Al) for biogas upgrading has been evaluated. Accordingly, firstly the breakthrough assessments of CO2 and CH4 adsorption onto this sorbents were studied. Afterwards, a pressure swing adsorption (PSA) process to this end was designed and developed. The results showed MIL-160(Al) has an excellent potential for biogas upgrading concerning CO2 and CH4 separation.

    Breakthrough experiments were properly simulated with ASPEN ADSIM. Cyclic steady state were developed after 10 cycles. Shaped MOF MIL-160(Al) showed and excellent capacity for Post-combustion CO2 Capture. Life cycle assessment (LCA) of MIL-160 for Postcombustion CO2 Capture can be considered as a future direction.

    The world currently faces the dual challenges: climate changes caused by global warming and a high energy demand regarding the exponential population expansion and industrial development [1, 2]. Carbon dioxide, methane, nitrogen oxide and halogenated components are the main anthropogenic greenhouse gases (GHGs) [1]. The challenge of reducing GHGs emission can be overcome by successful developing post-combustion CO2 capture also advancing the green and renewable sources of energy including biogas [3]. Nevertheless, the main drawback concerning the biogas is its high content on carbon dioxide (it might be as high as 40% or more), which significantly reduces its heating capacity. Therefore, for biogas applications, a previous separation step is required to reduce the CO2 content [2,3]. Among the different methodologies for biogas upgrading and postcombustion CO2 capture, adsorption is among the most attractive ones
