11. Catalyst Deactivation by Coke Formation in Acetylene Hydrogenation
Sammanfattning : Several aspects of catalyst deactivation have been studied with reference toselective acetylene hydrogenation, a reaction used industrially to purify ethylene from unwanted acetylene. A mathematical model has been developed for an industrial packed-bed reactor, employing a supported Pd catalyst. LÄS MER
12. Vehicle emissions abatement: NO oxidation and ammonia SCR
Sammanfattning : The design and the development of catalytic systems for reducing vehicle emissions is a complex task due to the variety of components in a wide range of gas flow and temperature. A complete system is, therefore, composed of a series of catalysts or catalytic systems, each of which is dealing with a particular aspect of the abatement process. LÄS MER
13. Interior Flow and Formation of Plain Orifice Sprays
Sammanfattning : This thesis will summarize recent experimental observations of spray formation in highly atomizing plainorifce sprays, the kind commonly produced by fuel injectors in compression ignition internal combustionengines. Two special interactions will be addressed in detail: primary atomization under elevated ambientpressures and temperatures and orifce ow effects on primary atomization. LÄS MER
14. Growing into Voting : Election Turnout among Young People and Habit Formation
Sammanfattning : This thesis contains an introduction and four essays that together address the issues of turnout and habitual voting. Although voting is less unequal than other forms of political participation, it is still biased in favour of more socially affluent citizens. One way to achieve more equal participation is to increase the general turnout. LÄS MER
15. Intrinsic Formation and Macroscopic Intervention in Multi-agent Systems
Sammanfattning : In this dissertation, we study two problems within the field of the multi-agent systems theory. One is the formation control for multiple reducedattitudes, which are extensively utilized in many pointing applications and under-actuated scenarios for attitude maneuvers. LÄS MER
