| Popis: | Solid amine sorbents were prepared using mixtures of linear and branched primary, secondary, and tertiary amines. These amines were immobilized within polystyrene (PS)-, silicon dioxide (SiO2)-, or polymethylmethacrylate (PMMA)-based substrates at various weight ratios. Testing was conducted in various reactor systems, where the reactive water required for the capture of carbon dioxide (CO2) was tracked during the adsorption/desorption cycles by mass spectrometer gas analysis. The water management for these sorbents was quantified and used to assess the technical feasibility of the operating conditions for the capture of CO2 from simulated flue gas streams. In addition, the heats of reaction and performance capture loading capacities of these sorbents were also determined by differential scanning calorimetry (DSC) and thermogravimetric analyses (TGAs), respectively, in both dry and humidified CO2 gas streams. The regenerable solid amine sorbents investigated in this study exhibit acceptable CO2-capture lo... |
