This book was released on 2011 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The capture and storage of CO2 from coal have received considerable attention due to a growing demand for green use of carbon-based resources concerning its global warming effect. There are usually two ways of capturing CO2 from coal-related gases according to locations of capture blocks, post-combustion and pre-combustion. The conventional approach for pre-combustion CO2 capture is liquid absorption. However, one potential limitation of this process is that the liquid scrubbing must occur at relatively low temperatures (near ambient). By contrast, adsorbent based processes offer the potential of higher temperature capture eliminating the intermediate cooling and reheating steps. Therefore there is a motivation to develop high temperature adsorption processes.This project investigates the capture of CO2 by solid adsorbents from pre-combustion coal gasification syngas in an Integrated Gasification Combined Cycle (IGCC) process at high temperatures. The project covers materials development and process testing on both a real gasifier and a synthetic pre-combustion gas stream provided in our laboratory.Adsorbents screening was performed with real coal gasification syngas from a pilot coal gasifier. Breakthrough and regeneration experiments with hydrotalcite MG 70, calcium chabazite, and zeolite 13X were performed on the custom-made gas separation apparatus at 120 °C and 200 °C. Zeolite 13X was found to be a potentially good adsorbent for CO2 separation provided T200 °C. Thereafter, different VPSA processes using zeolite 13X were designed to pursue a CO2 purity of 95% with synthetic syngas. The designed processes were then validated with real coal gasification gas. However, simulation results for the separation from full scale syngas showed that using zeolite 13X to reach a purity of > 95% would be very costly.High temperature adsorbents composed of MgO and K2CO3 were prepared and characterized by various means. These prepared adsorbents possessed high CO2 sorption capacity and cycling stability both under dry and wet conditions. An adsorption model was proposed for the prepared adsorbent and provided an adequate description of the adsorption and desorption experiments performed on a thermogravimetric analyser. The derived isotherm from the proposed model was also able to represent the experimental isothermal adsorption data well. Although the CO2 adsorption kinetics of these adsorbents were higher than other reported high temperature adsorbents, they were still much slower than widely used physical adsorbents, which makes it currently not very efficient for pressure swing adsorption processes. In future work, efforts will be focused on increasing the adsorption and desorption kinetics by, for example making these adsorbents to nanoscale, possibly supported on porous substrates.

Book excerpt: Absorption-Based Post-Combustion Capture of Carbon Dioxide provides a comprehensive and authoritative review of the use of absorbents for post-combustion capture of carbon dioxide. As fossil fuel-based power generation technologies are likely to remain key in the future, at least in the short- and medium-term, carbon capture and storage will be a critical greenhouse gas reduction technique.

This book was released on 2019-04-08 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted. Recent analyses found that deploying NETs may be less expensive and less disruptive than reducing some emissions, such as a substantial portion of agricultural and land-use emissions and some transportation emissions. In 2015, the National Academies published Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration, which described and initially assessed NETs and sequestration technologies. This report acknowledged the relative paucity of research on NETs and recommended development of a research agenda that covers all aspects of NETs from fundamental science to full-scale deployment. To address this need, Negative Emissions Technologies and Reliable Sequestration: A Research Agenda assesses the benefits, risks, and "sustainable scale potential" for NETs and sequestration. This report also defines the essential components of a research and development program, including its estimated costs and potential impact.
