such as zeolites and aluminophosphates are high surface area materials with great potential for catalysis, filtration and gas separation
applications. The application criteria require that these microporous ceramics,
which are produced in powder form, are assembled into mechanically strong hierarchically porous structured
bodies. In this regard,
pulsed current processing (PCP) has emerged as a binderless processing method
to structure microporous ceramics to hierarchically porous materials without
addition of binders. The rapid thermal processing using PCP of porous ceramic powders
will be presented to produce volumetrically efficient hierarchically porous structured
monoliths and laminates with properties to overcome the limitations of
conventional adsorbent materials specifically for decarbonization of power-plant
flue gas and biogas streams. We will demonstrate that pulsed current processing (PCP) is a versatile
tool to structure porous adsorbents without addition of binders in form of
monoliths and laminates and outperform conventionally structured zeolites in
all aspects of post-combustion decarbonization of gas streams, including CO2
uptake capacity, high CO2 over CH4 and CO2
over N2 selectivity, rapid uptake and release kinetics and
mechanical stability. Moreover, rapid thermal processing of
hierarchically porous aluminides and silicides will be introduced by an energy
saving method.<!--[if gte mso 9]> |
