This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomethane is a proven source of clean energy, it is one of the most cost-effective and environment-friendly substitute for natural gas and diesel. The European Union primary energy production from biomethane has folded by ~23 times in a 5 years time period (2011-2016) making necessary to find new and improved solutions for the separation of methane (CH4) and carbon dioxide (CO2), main components of biogas. In this context, the objective of this doctoral thesis is the determination of performance indicators such as the adsorption capacity and selectivity of activated carbons (ACs) for the CH4/ CO2 separation. This work focuses on the adsorption properties of activated carbons for the methane/carbon dioxide separation. To this end, CH4 and CO2 pure gas experimental adsorption isotherms of activated carbons were obtained on a pressure range of 0.1 to 3 MPa) and temperatures ranging from 303 to 323 K. The first part of this thesis project consisted in the analysis of the CH4 and CO2 pure gas adsorption properties of 5 commercial activated carbons Using a set of five commercial activated carbons a linear relationship between the adsorbent surface area and the CO2 adsorption capacity was determined. The micropore volume also showed a direct influence on the adsorption capacity. The second part of this work consisted in the study of the carbon dioxide and methane adsorption behavior of biomass-based activated carbons. Using a series of 3 ACs that had been obtained from olive stones by different activation methods, the activation technique proved to be of mayor importance as it determines the textural and chemical properties of the adsorbent and thus its gas adsorption capacity.Lastly, the CH4/CO2 adsorption selectivity of the 5 commercial activated carbons was calculated from the equimolar mixture adsorption isotherms. The selectivity factor was proven to be dependent on the sum of textural and chemical properties of the samples. Although, activated carbons with high average pore sizes and surface areas depicted higher adsorbed quantities it was on detriment of their selectivity. The selectivity was found to be better for the activated carbon showing an intermediate surface area and a narrow pore size distribution. In addition, the presence of sulfur functionalities was also found to improve the adsorption selectivity. Overall, this work shows that activated carbons are competitive materials for the upgrading of biogas, displaying adsorption properties comparable to those of other commercially available materials.

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.

Download or read book Gaseous Carbon Waste Streams Utilization written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-02-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.

Download or read book Biomethane written by Sirichai Koonaphapdeelert and published by Springer Nature. This book was released on 2019-11-06 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses biomethane and the processes and applications downstream from biogas production. Biogas is a result of anaerobic digestion of agricultural or general household waste, such as manure, plants or food waste, and as such is considered a renewable energy source. Biomethane is a gas that results from any process that improves the quality of biogas by reducing the levels of carbon dioxide, hydrogen sulfide, moisture and other contaminant gases. Chemically, biomethane is the same as methane, and its name refers to the method of production rather than the content. Biomethane plants are generally found in locations with a low population density that are close to farms or food processing plants. In situations where there is no natural gas pipeline nearby, biomethane downstream applications can include storage, transportation, home heating, industrial use and distribution through small-scale local gas grids. This book discusses each of these applications and lists some of the design criteria as well as various issues relating to them.
