dc.description.abstract | Greenhouse gases have become a consequential global issue. Carbon dioxide (CO2) is the most abundant greenhouse gas, that is significantly contributing to disastrous changes in the global climate. The escalating levels of carbon dioxide emissions in atmosphere have incited the implementation of breakthrough technologies to lessen its impact on the atmosphere.
In this work, CO2 capture from the atmosphere (i.e., direct air capture) was studied and investigated by using three commercial adsorbents of the zeolite type 13X (MSC-544, MSC 542, and SP-564), with average particle diameter of 0.00205, 0.00375, and 0.006 m, respectively. The breakthrough behavior was predicted as a function of the flowrate by keeping both inlet concentration and the temperature constant at 400 ppm and 19℃, respectively and operating at atmospheric pressure. The flowrates investigated were, 25.3, 31.6, and 38 m3 /hr, which were equivalent to superficial velocities of 0.2, 0.25, and 0.3 m/sec, respectively. [...] | |
