▎ 摘　　要

NOVELTY - Sorbent comprises silica, carbonaceous material, and epoxy modified aminopolymer. USE - Sorbent used in system for carbon dioxide removal from ambient air (claimed). ADVANTAGE - The sorbent shows minimum degradation by oxygen (O2) and thermal desorption over long-term adsorption and desorption cycles, can readily achieve ≯95+% CO2 purity for CO2 sequestration or downstream utilization, and has improved the stability. The CO2 can be separated from the entire sorbent-laden fabric filter (FF) during the desorption phase. The FF can be sequentially replaced from the front. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a method for removing carbon dioxide (CO2) from ambient air, which involves: providing a flow of ambient air across the sorbent; 2. a method for regenerating the sorbent, which involves: heating the sorbent to above 70℃ at below 0.9 atm and flowing CO2or steam across the sorbent; and 3. a system for removing CO2from ambient air, which comprises: a sorbent.
