Post-combustion Carbon Dioxide Capture Using Amine Functionalized Solid Sorbents
This work is divided into two parts: (1) Synthesis of amine functionalized adsorbents using grafting technique for post-combustion CO[subscript 2] capture, (2) Performance evaluation of structured bed configuration with straight gas flow channels using amine impregnated adsorbent for post-combustion CO[subscript 2] capture. Brief description of each part is given below: (1)N-(3-trimethoxysilylpropyl)diethylenetriamine (DAEAPTS) grafted SBA-15 adsorbents were synthesized for CO[subscript 2] capture. The adsorption of CO[subscript 2] on the amine-grafted sorbents was measured by thermogravimetric method over a CO[subscript 2] partial pressure range of 8-101.3 kPa and a temperature range of 25-105 °C under atmospheric pressure. The optimal amine loaded SBA-15 adsorbent was examined for multi-cycle stability and adsorption/desorption kinetics. (2)The performance of structured bed and packed bed configurations for post-combustion CO[subscript 2] capture was evaluated using PEI impregnated SBA-15 adsorbent. The effect of adsorption temperature (25-90 °C), adsorption /desorption kinetics and multi-cycle stability was studied in both structured and packed bed configurations.

Inorganic solid adsorbents/sorbents are attractive materials for capturing carbon dioxide (CO2) from flue gases after fossil fuel combustion. Post-combustion Carbon Dioxide Capture Materials introduces the key inorganic materials used as adsorbents/sorbents with specific emphasis on their design, synthesis, characterization, performance, and mechanism. Dedicated chapters cover carbon-based adsorbents, zeolite- and silica-based adsorbents, metal–organic framework (MOF)-based adsorbents, and alkali-metal-carbonate-based adsorbents. The final chapter discusses the practical application aspects of these adsorbents used in carbon dioxide capture from flue gases. Edited and written by world-renowned scientists in each class of the specific material, this book will provide a comprehensive introduction for advanced undergraduates, postgraduates and researchers from both academic and industrial fields wishing to learn about the topic.
