Synthesis of porous carbon adsorbents through carbonization of polymer precursors
Porous carbons have been widely used in adsorption-based separation processes such as pressure swing adsorption (PSA) because they have great textural properties (i.e. BET surface area). Fabrication of porous carbon adsorbents from carbonization of polymer precursors has advantages for developing uniform size of pore structure and upcycling plastic waste.
(Application/potentials)
Bulk CH4, CO2 removal
Upcycling of plastic waste
Development and characterization of high-temperature CO2 sorbents
Carbon dioxide (CO2) is a representative greenhouse gas and causes serious environmental problems. High-temperature CO2 sorption has been investigated as a new CO2 capture technology because most of the CO2 in flue gases is emitted at high temperatures. For application to high-temperature CO2 sorption, solid sorbents should have a high sorption working capacity with a fast sorption/desorption kinetics and good stability. High-temperature CO2 sorbents can also be used for sorption-enhanced reactions to produce high-purity hydrogen directly.
(Application/potentials)
Direct removal of high-temperature CO2 (from flue gases)
Applying to the sorption-enhanced reaction (SER) processes
Fabrication of H2 permeable metallic membranes
Membrane technology has attracted growing interest in minimizing the operational cost of H2 separation. VB refractory metals including V, Nb, and Ta gained significant attention because of their high permeability toward H2. However, those metals have low catalytic activity for the dissociation/association of H2, so catalytic layers are required on both sides of the membrane. The metallic composite membranes have great potential to be applied to separation processes for fuel-cell grade high-purity H2 and/or those for synthesizing H2 storage chemicals depending on the catalytic layer used.
(Application/potentials)
Fuel-cell grade H2 purification
Membrane reactor for producing chemically hydrogen storage agents (e.a. Alcohols, HCOOH, and NH3)
Characterization of catalytic-sorbents for CO2 utilization
For net-zero emission, the captured CO2 should be utilized or properly stored. A new type of reactive separation process could be developed by developing novel dual-function materials that can capture CO2 and catalyze hydrolysis and other reactions. The catalytic sorbents can be applied not only to the carbon capture and utilization (CCU) processes but also to the advanced blue hydrogen production system that simultaneously produces high-purity H2 and syngas.
(Application/potentials)
Control of the chemical properties of the solid sorbent surface
Next-generation energy carrier production system
