  2. 1. Structured Nanoporous Materials for Biogas Upgrading

    Author : Kritika Narang Landström; Farid Akhtar; Andreas Kaiser; George Shimizu; Marta-Lena Antti; Manuel Moliner Marín; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoporous materials; biogas upgrading; zeolites; metal-organic framework; carbon capture; separation kinetics; Materialteknik; Engineering Materials;

    Abstract : Porous materials have shown potential for solving one of the significant challenges to sequestering CO2 gas from point sources. Microporous materials, zeolites and metal-organic frameworks (MOFs) are porous materials with tailorable adsorptive properties to develop higher performance for an energy-efficient CO2 separation.

    Abstract : Porous materials are frequently used in everyday applications including food science, pharmaceuticals, fuel cell membranes, batteries and solar cells. A key aspect in these porous materials is how their micro- and nano-structure affect the internal transport of for example water, particles or charges. The transport is a three-dimensional process.
