EXPERIMENTAL STUDY ON HIGH PRESSURE COMBUSTION OF DECOMPOSED AMMONIA: HOW CAN AMMONIA BE BEST USED IN A GAS TURBINE?
Hydrogen is a challenging gas to transport and store, unless it is transformed to ammonia, a worldwide distributed chemical. Ideally, ammonia would be used directly on site as a fuel, but it has a very low reactivity and a high propensity to generate NOx. Alternatively, it can be decomposed to a...
Varying Ignition Quality of a Fuel for a HCCI Engine Using a Photochemically-Controlled Additive: The Development of a ‘Smart’ Fuel
This study examines the possibility to provide control over ignition timing in a homogeneous charge compression ignition engine (HCCI) using a fuel additive whose molecular structure can be adapted upon exposure to UV light. The UV adapted molecule has a greater influence on retarding ignition than...

Simulation of chemical looping combustion process in a double looping fluidized bed reactor with cu‐based oxygen carriers
Modeling and Simulation of Chemical Looping Combustion Using a Copper-Based Oxygen Carrier in a Double-Loop Circulating Fluidized Bed Reactor System
In this work, a computational fluid dynamics simulator has been developed for a novel double-loop circulating fluidized bed reactor which is used for a chemical looping combustion process. The simulator is implemented in an in-house code including the kinetic theory of granular flow and reaction...
Chemical Looping Combustion of Methane Using a Copper-based Oxygen Carrier in a 150 kW Reactor System
Chemical looping combustion experiments have been conducted in the 150 kW CLC reactor at SINTEF Energy Research in Trondheim with good results. Methane was used as fuel and porous copper oxide based particles, with a bulk density of 800 kg/m3 were, used as oxygen carrier. At a fuel power of 140 kW...
