Abstract:

As part of a collaborative Carbon Management Canada project, the extent and causes of attrition for three proposed carbon dioxide capture sorbents for fluidized power generation systems was investigated. The sorbents are crushed limestone, lime-based pellets containing calcium aluminate cement binder, and the same pellets with a mesoporous silica coating replacing the binder. The tested sorbents were provided by the University of British Columbia, the University of Ottawa/CANMET, and Laval University, respectively. The attrition testing equipment was an air-jet apparatus based on the ASTM

Abstract:

This thesis focuses on studying the synthesis of calcium oxide- (CaO-) based sorbents for carbon dioxide (CO2) capture in the post-combustion process. Calcium oxide has been regarded as one the most promising candidates for carbon capture in the last decade due to its high capturing efficiency, low running cost, and abundance in the natural world. However, the main drawback of this category of sorbents (natural limestone and modified CaO) is the rapid decay of the CO2 uptake capacity during the cycles of carbonation and decarbonation reactions. Therefore the target of this research is to enhan

Abstract:

Carbon is prepared from flax shive by treatment with sulphuric acid. The optimised conditions of preparation were based on metal sorption (Cd2+, Hg2+), carbon yield, and acid and energy consumption. The carbon product retains its fibrous woody texture and XRD indicates an amorphous structure which has a very low surface area determined by nitrogen adsorption. Elemental analysis of the sorbent shows a very low amount of sulphur (-1%), while FTIR shows the presence of carboxyl, carbonyl and hydroxyl (or phenolic) groups. Cadmium shows fast kinetics of sorption for this material reaching equilibr

Mineralization has the potential to capture CO₂. In nature, mineralization is the chemical weathering of alkaline-earth minerals in which stable carbonate minerals are formed, which leads to the removal of CO₂ from the atmosphere. The adsorptive carbonation reaction of olivine ((Mg,Fe)₂SiO₄)), consisting mainly of pure magnesium silicate (Mg₂SiO₄), a main constituent of the Earth’s crust, was carried out to estimate its potential application to the separation of CO₂ in the presence of water vapor in combustion plumes.

Abstract:

Calcium oxide (CaO) is a superior sorbent that captures carbon dioxide (CO2) to form calcium carbonate (CaCO3). This carbonation reaction plays important role in the production of a future cleaner fuel like hydrogen (H2) from biomass gasification, as it drives the water-gas shift reaction toward higher H2 yield. The CaCO3 can be calcined to regenerate CaO,,thus the CaO is utilisable for carbonation and calcination cycles in biomass gassifier. Despite its superiority and regenerability, the decay of CaO reactivity due to siritering remains a challenge to its stability over multiple cycles. Othe

碩士<br>國立高雄應用科技大學<br>化學工程與材料工程系碩士在職專班<br>102<br>In recent years, global warming has triggered enormous public concerns and severe environmental problems. The increases of CO2 concentration in the atmosphere due to the rapid development of industrial has been caused by the consumption of huge amounts of fossil fuels. In order to reduce CO2 emissions, many researchers focus on developments of CO2 capture and sequestration. A preliminary analysis from US indicated that an economically feasible approach for CO2 capture should further cost-down to less than US $30. Thus, it is urgent to develop low

Abstract:

碩士<br>國立中興大學<br>環境工程學系<br>90<br>The objective of this study is to investigate the possibility of using carbon supporting metals catalyst/sorbents for the removal of SO2 from flue gas, expected to achieve higher SO2 conversion and sorbents utilized efficiently. The catalyst/sorbents were prepared by impregnating the carbon powders with the aqueous solutions of the nitrate of the metals. They are Cu/A.C., Ce/A.C. and Cu-Ce/A.C. catalyst/sorbents, respectively. A dry scrubber integrated with a frabic filter was employed in the pilot-scale fluidized bed incinerator to demonstrate the pe

Abstract:

abstract: Post-combustion carbon capture is a viable option for reducing CO2 greenhouse gas emissions, and one potentially promising technology for this route is adsorption using chemically and physically based sorbents. A number of exceptional CO2 sorbents materials have been prepared including metal organic frameworks, zeolites, and carbon based materials. One particular group of capable materials are amine based solid sorbents that has shown to possess high adsorption capacities and favorable adsorption kinetics. A key variable in the synthesis of an amine based sorbent is the support which

Abstract:

Ever increasing anthropogenic emissions of greenhouse gas carbon dioxide (CO₂) are considered as the main driving force behind climate change on Earth. Despite the incentives surrounding carbon-free energy, it will take decades until significant market penetration is achieved. In the meantime, while carboneous fossilized energy sources continue to dominate the energy blend and worldwide energy demand is continuously increasing, carbon capture and storage (CCS) can offer an immediate solution to fight climate change. Several high temperature CO₂ capture technologies are under development

Thesis (MTech. degree in Mechanical Engineering)--Tshwane University of Technology, 2009.<br>South Africa produces 41.3 GWe per year of which 90% is coal-derived. During combustion of coal, sulfur contained in the fuel is converted to SO2. The gas poses a serious danger for the human and environmental health. The health hazards associated with SO2 include hair loss, throat inflammation, impaired vision and respiratory illnesses. Sulfur dioxide is also forms acid rain, which leads to acidification of soils, waterways and forests. The main objective of this investigation is to explore methods of
