Abstract:

Les zéolites ont de nombreuses applications dans l'industrie chimique et pétrochimique en tant que catalyseurs et adsorbants en raison de leurs canaux réguliers et des cavités avec des tailles inférieures à 2 nm, de grandes surfaces, une forte acidité, et une sélectivité de forme. Cependant, l'inconvénient est que l'absorption et le rendement catalytique de zeolites est souvent compromise en raison du fait que les réactifs et les produits peuvent être confrontés à de graves limitations de la diffusion intra-pores. Par conséquent, une variété d'approches ont été conçues afin de réduire les rest

Abstract:

In this study wettability and floatability of coal petrographic components were examined using the concept of critical surface tension. Two techniques were studied; film flotation and small-scale flotation tests. Both tests use Zisman’s concept of critical surface tension of solids. In these tests particles are separated according to their respective critical surface tension of wettability (film flotation) or critical surface tension of floatability (small-scale flotation). Surface heterogeneity of coal particles arises from the chemical composition of coal surface. The coal macerals are know

Abstract:

The upgrading of fluid catalytic cracking (FCC) gasoline is a significant refinery process which is required to decrease FCC gasoline's alkenes and organosulfur compounds (OSCs) levels to meet stringent, regulated specifications, whilst maintaining or increasing the octane number. The separation and recovery of alkene contents in gaseous alkene and alkane mixtures produced in the refining process is presently a substantial consumer of both energy and resources. The current processes for these upgrading or separation processes rely heavily upon energy - intensive technologies which require seve

Abstract:

Direct methanol fuel cells (DMFCs) are considered a clean source of electrical power for future energy demand, creating a potential to reduce our dependency on fossil fuels. Despite their advantages, including high energy density, efficiency and easy handling and distribution of fuel, the commercialization of DMFCs has suffered from some drawbacks, including methanol crossover and contamination of the system. Metal cation contaminants (such as Ni, Co, etc) introduced through the degradation of fuel cell components (bipolar plate and electro-catalyst layer) can significantly affect the Nafion-m

Abstract:

Due to the ductile nature of the sodium nitrate crystal which deforms plastically under high levels of strain, most of the crystal growth studies in aqueous solution have focussed on the influence of tensile strain, supersaturation and dislocation, using x-ray surface topography to characterise the dislocation structure of the crystal. Most of the crystal growth studies have also focussed on growth from the melt since single crystals of sodium nitrate find application in optical pumping experiments, are a potential substitute for calcite in the preparation of polarising prisms and are interest

Abstract:

碩士<br>國立中山大學<br>化學系研究所<br>100<br>Perfluororated proton exchange membrane Nafion is the mostly used type of ion exchange membrane in fuel cells. Over the past decades, various studies have been carried out on their structures at different scales, proton conduction mechanism, electrochemical performance, thermal and mechanical properties etc, but many problems are still open, such as the precise picture of proton conduction, degradation and aging of the membrane, even the distribution of pores and channels etc. Because membrane degradation is crucial for practical operation of fuel cells and its

Abstract:

Electrolyte solutions play a central role in life and technological processes because of their complexity. This complexity is yet to be described by a predictive theory of the specific effects that different ions induce in solution. The vast majority of investigations of specific-ion effects have been conducted in aqueous solutions. These studies have revealed that amongst the complexity, the effectiveness of the ions often follow trends that are apparent across a number of very different experiments, revealing an underly
