Capture of carbon dioxide from flue gas using amine functionalized silica based adsorbents has shown great potential recently. Despite their stable performance, the full potential of these adsorbents has not been researched in greater depth. In this thesis, experimental study and simulation of a...

Oxyfuel combustion as one of the alternatives to post-combustion carbon capture technologies requires an economically viable oxygen supply system. Cryogenic air separation, the main currently available technology, consumes above 30% of the energy produced as it involves separation of nitrogen...

Direct coal liquefaction is a technology for producing liquid products from coal. One of the by-products from this process is coal liquefaction residue, which is remaining coal that was not converted to liquid products during the liquefaction process. The residue is enriched in mineral matter and...

Modelling of solvent extraction was studied using 1,2,3,4–tetrahydronaphtalene (tetralin) and Poplar coal (lignite). A kinetic model was developed taking into account temperature, mass transfer limitations and dominating events (physical or chemical) during coal liquefaction. It was found there...

The oxidative denitrogenation of quinoline (as a model compound representing the nitrogen containing structure of coal liquids) has been investigated in two steps: oxidation by perdecanoic acid at 50 ˚C to produce quinoline N-oxide in order to weaken the nitrogen-carbon bond; thermal...

In recent years the need for new carbon sources to supplement crude oil for the production of fuels and chemicals, again focused on coal as suitable candidate. Old and new technologies are being developed to convert coal in valuable products. An old technology such as solvent extraction of coal...

The stability of the ether bond affects coal dissolution during direct coal liquefaction and aliphatic ethers are reportedly the most reactive of the oxygenate classes during liquefaction. Some ether compounds are also persistent to high temperature during coal pyrolysis. The thermolysis of ether...

Hydrogen (H2) can play a critical role in global greenhouse gas (GHG) mitigation. Photoelectrochemical water splitting using solar radiation is a promising H2 technology. Titanium dioxide (TiO2)- and carbon nitride (g-C3N4)-based photocatalysts are the most widely used photocatalytic materials...
