Performance evaluation for a thermal swing honeycomb rotor adsorber using a humidity chart.

Structured adsorbents in gas separation processes

“…These adsorbents are usually made by impregnation of ceramic papers and corrugating the sheets in order to create the honeycomb structure [21,[56][57][58][59][60]. In the study conducted by Kim et al [36] zeolite paper in the form of honeycomb rotors was employed in the removal of trace amount of VOCs.…”

Entropic analysis of adsorption open cycles for air conditioning. Part 1: first and second law analyses

“…The open cycle for adsorption ventilation and air conditioning is schematically presented in Figure 1 (Kodama et al, 1993(Kodama et al, , 1994(Kodama et al, , 1995. The #ow of external air (1)R is admitted into the unit and "rst dried while #owing through the desiccant wheel, the dehumidi"er D. Owing to the heat of adsorption, the air is also heated (2).…”

“…This remark leads to the second point: this technique, that e$ciently supplies altogether air-conditioning and ventilation, is quite healthy because the external air blown through the adsorbent wheel is meanwhile disinfected (Kovak et al, 1997). Third, the thermodynamic e$ciency is good (Collier et al, 1982;Van den Bulck et al, 1986;Krishna and Murthy, 1989;Waugaman et al, 1993;Kodama et al, 1995;Kuma et al, 1998). For instance, low-grade heat at about 803C can easily be used, which should permit to implement a rotary adsorbent airconditioner into a combined cold and power installation.…”

“…Most of the time, the adsorbent is a silicagel or a product derived from silicagel. Many works are dedicated to experimental approaches of these cycles (Krishna and Murthy, 1989;Kodama et al, 1993Kodama et al, , 1994Kodama et al, , 1995 or numerical approaches, especially models of the desiccant wheel itself (Van den Bulck et al, 1985a, b;Farooq and Ruthven, 1991). They often deal with optimization of operating conditions (rotation speed, air #ow rate, regeneration temperature, etc.).…”

Entropic analysis of adsorption open cycles for air conditioning. Part 2: interpretation of experimental data

“…The adsorbent rotor is a silica-base composite supported by the honeycomb matrix of alumina "ber paper. Details of the performance are discussed in the previous papers (Kodama et al, 1993(Kodama et al, , 1994(Kodama et al, , 1995Kuma and Hirose, 1996).…”
