Abstract
The thesis is focusing on the potential roles and applications of NH\(_3\) in transportation area, where ammonia is applied i) as a hydrogen carrier involved in a catalytic reforming process tor H\(_2\) production, ii) in its reformed form i.e. H\(_2\) -NH\(_3\) mixture for improved NH\(_3\) combustion in CI engines (as a carbon-free energy carrier), and iii) as a reductant in engine emission abatement under the incorporation of the NH\(_3\) reforming mechanism and catalytic aftertreatment systems.
To implement the above studies, a prototype reformer system and a catalytic reaction mechanism were designed and proved capable of producing Hz - contended reformate. The reformed NH\(_3\) i.e. H\(_2\) - NH\(_3\) mixture was later applied in diesel operation and demonstrated successful engine decarbonisation. With a further incorporation of a Silver/Alumina catalyst in the engine exhaust system, the reformate was revealed as viable reductant for low temperature NOx abatement. Therefore, a combination of the studied systems show a great potential in simultaneous diesel engine emissions reductions, which include CO\(_2\), CO, HC, PM and NOx.
