摘要：

A polyethylenimine (PEI)-silica adsorbent-based true moving bed adsorption process with a heat integration scheme was investigated as an energy conservative CO2 capture process. The process was configured using four separate beds with internal plate heat exchangers for adsorption, cooling, desorption and heating. An in-house steady-state simulator was constructed to analyze process behaviors, which focused on the energy demand and bed size under various operating conditions. A recently developed amine-functionalized adsorbent, 0.37EB-PEI, which uses silica fume as a support, was utilized in the process.
