Energy and Exergy Analysis of a Cruise Ship

Tuong-Van Nguyen, Francesco Baldi, Karin Andersson

In recent years, the International Maritime Organization agreed on aiming to reduce shipping’s greenhouse gas emissions by 50% with respect to 2009 levels. Meanwhile, cruise ship tourism is growing at a fast pace, making the challenge of achieving this goa ...

Experimental Studies of the Snowflake Divertor in TCV

Basil Duval, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Umar Sheikh, Federico Nespoli, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Wouter Vijvers

To address the risk that, in a fusion reactor, the conventional single-null divertor (SND) configuration may not be able to handle the power exhaust, alternative divertor configurations, such as the Snowflake divertor (SFD), are investigated in TCV. The ex ...

Relationship between structures and activities of supported metal vanadates for the selective catalytic reduction of NO by NH3

Adrian Marberger, Davide Ferri, Oliver Kröcher

Transition and rare earth metal vanadates are potential active phases for the selective catalytic reduction (SCR) of nitric oxide by ammonia for exhaust gas emission control. In this work, various metal vanadates mixed with SiO2-WO3-TiO2 (TWS) were compare ...

Deactivation Aspects of Methane Oxidation Catalysts Based on Palladium and ZSM-5

Davide Ferri, Mohamed Tarik

Catalytic methane oxidation is used in exhaust gas after treatment to reduce methane emissions in stationary combustion processes as well as in natural gas vehicles. Pd/zeolite catalysts provide higher activity than the commonly used Pd/Al2O3, but suffer f ...

Advances in Vanadium-Based Catalyst Research for the Selective Catalytic Reduction of NOx by NH₃

Adrian Marberger

The most efficient after-treatment technology for reducing harmful NOx emissions from stationary and mobile sources of diesel exhaust is the selective catalytic reduction (SCR) of NOx with ammonia (NH3). Vanadium-based SCR catalysts reduce NOx selectively ...

Testing and modelling of a novel oil-free co-rotating scroll machine with water injection

Jürg Alexander Schiffmann, Luis Carlos Mendoza Toledo

Efficient compressed air energy storage requires reversible isothermal compression and expansion devices. The isothermal compression and expansion processes can either be approached by several stages with intercooling or by the more convenient injection of ...
