Evaluation of activated carbons produced from Maize Cob Waste for adsorption-ba...
Surra, Elena; Ribeiro, Rui P.P.L.; Santos, Tiago; Bernardo, Maria; Mota, José P.B.; Lapa, Nuno; Esteves, Isabel A.A.C.Two activated carbons (AC) resulting from CO2 activation of Maize Cob Waste (MCW) were investigated as adsorbent materials for biogas upgrading to bio-methane applying a biorefinery concept. The porous carbons were originated from different times of activation and the one resulting from 3 h with CO2 (MCW(PA)3 h) showed better textural properties, higher working capacity, and selectivity towards CO2 than the car...
Impact of Ionic Liquid Structure and Loading on Gas Sorption and Permeation for...
Ortiz-Albo, Paloma; Ferreira, Tiago J.; Martins, Carla F.; Delgado Alves, Vitor; Esteves, Isabel A.A.C.; Cunha-Silva, Luís; Kumakiri, IzumiCarbon dioxide (CO2) capture has become of great importance for industrial processes due to the adverse environmental effects of gas emissions. Mixed matrix membranes (MMMs) have been studied as an alternative to traditional technologies, especially due to their potential to overcome the practical limitations of conventional polymeric and inorganic membranes. In this work, the effect of using different ionic li...
Cr-based MOF/IL composites as fillers in mixed matrix membranes for CO2 separation
Ferreira, Inês C.; Ferreira, Tiago J.; Barbosa, André D.S.; Castro, Baltazar; Ribeiro, Rui P.P.L.; Mota, José P.B.; Delgado Alves, VitorNew composite materials made of bromide-based ionic liquids (ILs) and metal–organic framework (MOF) MIL- 101(Cr) were produced using two different ILs. The powdered composites [PMIM][Br]@MIL-101(Cr) and [BMIM][Br]@MIL-101(Cr) were rigorously characterized, and it was confirmed that both ILs were incorporated into the MOF structure. Single-component CO2 and N2 adsorption–desorption isotherms for the pristine MIL...
