Resumen

The average energy consumption of one ice rink is around 1000MWh/year, which approximately69% is occupied by the refrigeration unit and heating demand. With the aim of decreasing theenergy consumption, a new concept of refrigeration system with CO2 as a refrigerant has beendeveloped and it is promising to become a high potential next generation for refrigeration systemin ice rink.This thesis is to evaluate a new refrigerant application in ice rink refrigeration system underthree different aspects; energy performance, heat recovery potential and economic efﬁciency.

Resumen

L'augmentation des émissions de dioxyde de carbone force l'implémentation de différentes stratégies de réduction des émissions de CO2 qui peuvent être divisées en deux groupes principaux: (i) Le captage du carbone et stockage (CCS) and (ii) le captage du carbone et utilisation (CCU). Un des procédés convertissant le CO2 en un produit à valeur ajoutée est le reformage à sec du méthane (DRM). Cependant le procédé de DRM n'a pas été commercialisé en raison de la forte endothermicité de la réaction et par manque de catalyseur actif, stable et bon marché à ce jour.

Cette thèse cherche à développer une méthode non-invasive de mesure du taux de dioxyde de carbone (CO2) artériel, dont la connaissance est cruciale sur le plan clinique. Deux approches principales sont étudiées : la carbamétrie pulsée, qui extrapole les principes de l'oxymétrie à la carbamino-hémoglobine via des techniques spectrophotométriques, et l’étude de la diffusion transcutanée du CO2, qui donne des indications sur le contenu en CO2 des tissus sous-cutanés. La première approche s'est révélée être une impasse, tandis que la seconde montre un plus grand potentiel. En particulier, la piste

Resumen

Silylated amines, also known as reversible ionic liquids (RevILs), have been designed and structurally modified by our group for potential use as solvents for CO₂ capture from flue gas. An ideal CO₂ capture ionic liquid should be able to selectively and reversibly capture CO₂ and have tolerance for other components in flue gas, including SO₂, NO₂, and O₂. In this project, we study the reactivity, selectivity, uptake capacity, and reversibility of RevILs in the presence of pure SO₂ and mixed gas streams tosimulate flue gas compositions.

Resumen

Atmospheric concentrations of carbon dioxide (CO2) are significantly increasing since the industrial revolution at an accelerating rate causing environmental impact such as global warming and climate change. Projections indicate that CO2 concentrations will continue to rise to unsustainable levels. This highlights the scale of the challenge our scientists are facing in order to reduce CO2 emissions and underpins the importance of promoting green process engineering for the utilisation of CO2 as a valuable commodity in the process industry.

Resumen

In order to combat climate change there is a need to achieve negative emissions. Bio-energy with carbon capture and storage (BECCS) is a promising technology that offers the possibility to remove carbon dioxide (CO2) emissions from the atmosphere. However, this also implies that the BECCS process needs to store more CO2 than it emits. The purpose of this study is to examine the liquefaction, intermediate storage, transportation and long term storage of CO2 and evaluate the climate impact of the energy use and the leakage of CO2.

Resumen

With the emission of carbon dioxide (CO2) becoming an international worry due its role in climate change, solutions such as CO2 capture and storage technologies are needed to decrease the emissions. The main proportion of CO2 gas emissions is from fossil fuel combustion in a range of industries, including power generation. To develop the CO2 capture system for these operations, new materials are needed for CO2 capture. Metal-organic framework (MOF) materials have porous crystal structures containing organic molecules (organic ligands) linked to each other by metalcontaining nodes. The large in

Resumen

Today’s society strives to eliminate the carbon dioxide (CO2) emissions, which is the main greenhouse gas emitted through anthropogenic activities and contributes to climate change. In this project utilization of CO2 emissions from waste to energy plants to carbohydrates via photocatalytic reduction with water and further carbon coupling reactions is investigated. Two routes for the synthesis of carbohydrates have been investigated. Both methods use photocatalytic reduction of carbon dioxide to methanol and then proceed via different steps to produce carbohydrates or their precursors. The firs

CO2 enrichment enhanced the dry weight of C3 and C4 Panicum species under optimal light and N supplies, but had no effect on the total leaf N or TNC concentrations.

Resumen

Carbon Capture and Storage (CCS) technology could help reduce anthropogenic CO2 emissions to the atmosphere. So far, CCS has failed to attract government support in the UK due to high costs of implementation. The broad deployment of CO2-EOR could aid the development of CCS by providing additional revenue streams for investors. The success of the CO2- EOR in the United States has raised the question of whether this success could be replicated in the UKCS. This thesis answers these questions by introducing two distinct models, which analyse the similarities and differences between the two oil pr

Resumen

A cleaner use of fossil fuels supported by Carbon Capture and Storage (CCS) techniques is considered to be one of the main short-term strategies for addressing the global climate change problem. However, potential CO2 or CO2/SO2 seepage during some of the phases of a CCS project not only reduces its performing efficiency, but also impacts the local environment, which could have further impacts on human health. It is therefore essential to assess the potential risks and provide evidence that the impacts are well understood. Moreover, studying the effects of CO2 leakage is useful for identifying

Carbon Capture and Storage (CCS) is recognised as having a significant role to play in tackling climate change and reducing carbon dioxide (CO2) emissions. In CCS schemes, CO2 is captured from anthropogenic sources, and transported to suitable sites either for EOR (Enhanced Oil Recovery) or storage. The transport of such huge amount of CO2 causes new challenges. The main concern is in the difference between natural gas and CO2 transportation pipelines. CO2 phase behaviour during decompression, existence of different impurities and very high operating pressure are some of the new challenges for

Resumen

El CO2 en la atmósfera aumenta a raíz del empleo de combustibles fósiles. La hidrogenación de CO2 ofrece una ruta única para transformar esta molécula en productos químicos o combustibles como el metanol. El uso de alta presión en el ratio CO2:H2 = 1:>3 permite incrementar la cinética de la reacción, alcanzando así la conversión termodinámica como ya se ha reportado. No obstante, el mayor inconveniente del mencionado proceso es el tratamiento del hidrógeno sin reaccionar. Por ello, se evaluaron las ventajas de realizar la reacción a alta presión en condiciones estequiométricas (CO2:H2=1:3

Resumen

Resumo: O presente estudo avaliou a reação do tecido conjuntivo irradiado com os lasers de CO2 e de Er:YAG em feridas confeccionadas no dorso de ratos. Foram confeccionadas 2 feridas no dorso de 30 ratos com um punch de 3mm de diâmetro. Os animais foram divididos em três grupos de 10: no Grupo I as feridas foram irradiadas com o laser de CO2, l 10,6 mm, (1,5 W -50 Hz); no Grupo II as feridas foram irradiadas com o laser de Er:YAG, l 2,94 mm (300 mJ -10 Hz), tempo de irradiação de 23 segundos em ambos os grupos; e no grupo III as feridas não foram submetidas à irradiação. Após o ato operatório,

Resumen

Soil CO2 efflux (F-soil) represents a significant source of ecosystem CO2 emissions that is rarely quantified with high-temporal-resolution data in carbon flux studies. F-soil estimates can be obtained by the low-cost gradient method (GM), but the utility of the method is hindered by uncertainties in the application of published models for the diffusion coefficient. Therefore, to address and resolve these uncertainties, we compared F-soil measured by 2 soil CO2 efflux chambers and F-soil estimated by 16 gas transport models using the GM across 1year. We used 14 published empirical gas diffusio
