Intensification of Adsorption Process in Porous Media

Abstract

This chapter presents research and ideas on the design and shape optimization of porous media and related process devices for rapid and efficient gas adsorption. In particular, we will focus on the intensified temperature swing adsorption (TSA) process by employing several methods such as thermal conductivity promoter, thermoelectric elements and cyclic operating mode, which illustrate well different aspects of the notion of intensification. Other methods for intensification of adsorption processes will be briefly discussed also in the context of pressure swing adsorption (PSA), of electro-thermal swing adsorption (ESA), and of the use of circulating fluidized bed (CFB). Finally, the design of a porous material or system with multi-scale internal geometry for gas adsorption and storage will be presented, expressing necessary compromises between mass and heat transport characteristics.
