Abstract:
Carbon Dioxide (CO2) emission from hydrocarbon fuel combustion is becoming a serious concern because it is the main contributor to greenhouse gas which causes global warming. Activated carbon sorbents have been used widely in various gas-phase and/or liquid-phase separation. Currently activated carbon (AC) is being investigated and developed for CO2 capture. Chicken waste, which is produced in large quantity in U.S., is currently disposed as waste. However, it may have a large benefit to turn chicken waste into useful activated carbon. In this research, a series of activated carbon have been g

Abstract:
The aim of this project is the design, synthesis and characterisation of porous carbon structures capable of the selective capture of carbon dioxide (CO2) from the exhaust gases of coal and gas post-combustion power stations. In such systems, the fossil fuel is burnt in an air environment producing CO2 as just one of a multi-component flue gas. This flue gas is expected to contain nitrogen and water among other constituents. It is at ambient pressures and temperatures of ≥323 K. Successful capture materials should have highly microporous structures, rapid sorption kinetics and be capable of re

In this work two research topics are presented: investigation of carbonation reactions of high – calcium waste materials and CO2 storage in coal. Firstly, sorption capacity of CO2 and CH4 of hard coal and associated sorption-induced expansion of the material was measured. This investigation was maintained in isothermal and non-isothermal conditions. Experiments were done on purpose-design apparatus allowing simultaneous measurement of sorption kinetics and sorption-induced swelling/contraction of coal.

The research described in this thesis relates to the development and optimisation of a novel polymerisation reaction and its subsequent use in the generation of novel ‘Polymers of Intrinsic Microporosity’ (PIMs).

This link not only strongly holds the polymer chain together, but also provides a site of contortion, which is necessary for a PIM to exhibit microporosity. The first part of this work introduces t

Abstract:
Novel highly functionalized hybrid organic-inorganic materials were synthesized by polycondensation of bis[3-(trimethoxysilyl)propyl]amine in presence of cationic and anionic surfactants. Reaction media strongly affected gelation time. Thus, in basic media gelation occurred immediately while acid increased gelation time. Material structures were studied by IR spectroscopy, porosimetry, XRD, and SAXS methods. In spite of the absence of an inorganic linker, obtained bridged silsesquioxanes had mesoporous structure. A material prepared in the presence of dodecylamine as a template had higher surf

Abstract:
The aim of this doctoral thesis is to develop and apply a kinetic model for the simulation of High Temperature Fuel Cells for energy conversion and Carbon Capture applications. In particular, the work will focus on the analysis and the modeling of a newly discovered mechanism in Molten Carbonate Fuel Cells that sees the net migration of H2O from the cathode to the anode side in competition with the usually encountered migration of CO2. This mechanism was never reported in the literature and was named "dual-anion mechanism" to underline the parallel migration of carbonate and hydroxide ions. It

Abstract:
This work considers the value of flexible power provision from natural gas-fired combined cycle (NGCC) power plants operating post-combustion carbon dioxide (CO2) capture in low carbon electricity markets. Specifically, the work assesses the value of the flexibility gained by varying CO2 capture levels, thus the specific energy penalty of capture and the resultant power plant net electricity export. The potential value of this flexible operation is quantified under different electricity market scenarios, given the corresponding variations in electricity export and CO2 emissions. A quantified a

Abstract:
This thesis explores the international political dynamics of developing low carbon technology. Specifically, Carbon Capture and Storage (CCS) technology as a climate mitigation strategy in a developing country context is examined. CCS is a technological solution that allows for the continued use of fossil fuels without the large amounts of associated CO2 emissions. This entails capturing the CO2 emitted from large point sources, such as a coal-fired power station, and transporting the captured emissions to be injected and stored permanently into geological media. Consequently, CCS is a bridgin

Abstract:
The main theme of this work revolves around the CO2 molecule, a stable waste gas of low value, low energy and often available in large quantities in different places. This work examines some viable avenues for capturing, using, and storing CO2 (CCUS), with the ultimate goal of reducing GHG emissions and global warming. In addition, the study also examines several ways to accelerate the commercialization of carbon-based products and their technologies. Various technologies that show promising features of commercial scalability and advanced mobility. In addition, the rapid decline in the costs

Abstract:
This work concerns the functionalisation of a variety of carbon materials for the selective adsorption of carbon dioxide. A key challenge in post-combustion capture from gas fired power plants is related to the low CO2 concentration in the flue gas (4- 8%). Therefore highly selective adsorbents have the potential to improve the efficiency of the separation of carbon dioxide from gas mixtures. The study was performed in conjunction with the EPSRC funded project ‘Adsorption Materials and Processes for Carbon Capture from Gas-Fired Power Plants – AMPGas’.
