Available in PDF, EPUB and Kindle. Book excerpt: Combustion of fossil fuels is one of the major sources of the greenhouse gas CO2. Pressure swing adsorption/sorption (PSA/PSS) and temperature swing adsorption/sorption (TSA/TSS) are some of the potential techniques that could be utilized for removal of CO2 from fuel gas streams. It is very important to develop sorbents to remove CO2 from fuel gas streams that are applicable for a wide range of temperatures. NETL researchers have developed novel CO2 capture sorbents for low, moderate, and high temperature applications. A novel liquid impregnated solid sorbent was developed for CO2 removal in the temperature range of ambient to 60 °C. The sorbent is regenerable at 60 - 80 °C. The sorbent formulations were prepared to be suitable for various reactor configurations (i.e., fixed and fluidized bed). Minimum fluidization gas velocities were also determined. Multi-cycle tests conducted in an atmospheric bench scale reactor with simulated flue gas indicated that the sorbent retains its CO2 sorption capacity with a CO2 removal efficiency of approximately 99% and was unaffected by presence of water vapor. The sorbent was subsequently commercially prepared by Süd Chemie to determine the viability of the sorbent for mass production. Subsequent testing showed that the commercially-synthesized sorbent possesses the same properties as the lab-synthesized equivalent. An innovative solid sorbent containing mixture of alkali earth and alkali compounds was developed for CO2 removal at 200 - 315°C from high pressure gas streams suitable for IGCC systems. The sorbent showed very high capacity for CO2 removal from a gas streams containing 28% CO2 at 200 °C and at 20 atm during a lab scale reactor test. This sorbent can be regenerated at 20 atm and at 375 °C utilizing a gas stream containing steam. High pressure enhanced the CO2 sorption process. Bench scale testing showed consistent capacities and regenerability. A unique high temperature solid sorbent was developed for CO2 capture at temperatures of 500 - 700°C. Bench scale testing of the sorbent yielded very high CO2 capture capacity from a gas stream containing 10% CO2, 30% H2, 15% H2O, and 25% He. Regeneration of the sorbent is possible at 800 - 900 °C.

Download or read book Capture of CO2 from Pre combustion Gas by Adsorption Processes at High Temperatures written by Gongkui Xiao and published by . 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.

Download or read book Pressure Swing Adsorption written by Douglas M. Ruthven and published by John Wiley & Sons. This book was released on 1996-12-17 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pressure Swing Adsorption is the first book that provides a coherent and concise summary of the underlying science and technology of pressure swing adsorption (PSA) processes at a level understandable to the practising engineer. PSA has achieved widespread commercial acceptance as the technology of choice for hydrogen purification, air separation and small scale air driers. However, PSA has numerous other actual and potential uses such as the recovery of methane from landfill gas, the production of carbon dioxide and other large scale applications. Since the design and optimization of a PSA process requires a somewhat mathematical model, two chapters of the book provide in-depth information on equilibrium theory and dynamic numerical simulation. However, this mathematical material will also help the general reader develop an understanding of the principles and strenghts and limitations of various approaches. PSA engineers, chemical engineers, environmental chemists, academicians and managers who must make informed decisions about purchasing costly PSA systems will find Pressure Swing Adsorption of particular value.
