“…A higher rate of the adsorption process is interpreted kinetically and behaviorally by the increase in steepness, which is indicative of a thinning of the mass transfer zone. However, it also implies shorter breakthrough time and lower adsorption capacity . You et al performed a simulation of the adsorption behavior at various feed gas temperatures.…”

“…A decrease in the inlet flow rate by less than 200 mL min –1 results in longer contact periods to retain the adsorbent, while shorter breakthrough times indicate shorter retention times (contact time between adsorbate and adsorbent). To keep more molecules in the pores or on the surface of the CO 2 adsorbent, extend the duration of the contact period …”

“…To keep more molecules in the pores or on the surface of the CO 2 adsorbent, extend the duration of the contact period. 152 Faster gas flow rates generally result in less effective adsorption because they shorten the time the gas and adsorbent are in contact during the adsorption process. However, the opposite has occurred in some studies.…”

High emission of carbon dioxide (CO 2 ) has caused CO 2 levels to reach more than 400 ppm in air and led to a serious climate problem. In addition, in confined spaces such as submarines and aircraft, the CO 2 concentration increase in the air caused by human respiration also affects human health. In order to protect the environment and human health, the search for highperformance adsorbents for carbon capture from high and low concentration gas is particularly important. Porous carbon materials, possessing the advantages of low cost and renewability, have set off a boom in the research of porous adsorbents, which have the opportunity to be utilized on a large scale for industrial carbon capture in the future. In this review, we summarize the recent research progress of porous carbons for carbon capture from flue gas and directly from air in the last five years, including activated carbon (AC), heteroatom-modified porous carbon, carbon molecular sieves (CMS), and other porous carbon materials, with a focus on the effects of temperature, water content, and gas flow rate of industrial flue gas on the performance of porous carbon adsorbents. We summarize the preparation strategies of various porous carbons and seek environmental friendly porous carbon materials preparation strategies under the premise of improving the CO 2 adsorption capacity and selectivity of porous carbon adsorbents. Based on the effects of real industrial flue gas on adsorbents, we provide new ideas and evaluation methods for the development and preparation of porous carbon materials.
