1. Mitigating Knock in Heavy Duty Spark Ignition Engines : Experiments and simulations of diluted ethanol and methanol combustion
Abstract : To effectively reduce fossil fuel dependence in the transport sector, an unprecedented increase in renewable fuel production is required. Short chain alcohols, such as ethanol and methanol, are well placed as they can be produced in a variety of renewable pathways from most carbon sources. READ MORE

2. Impact of Fuel Properties on Partially Premixed Combustion
Abstract : Compression ignited engines generally have higher efficiency than spark ignition engines. However, the most common combustion concept in compression ignited engines, conventional diesel combustion, struggles with high levels of particulate matter and NOx emissions. READ MORE

3. Ethanol Production from Cellulosic Biomass by Encapsulated Saccharomyces cerevisiae
Abstract : Unstable oil markets with rising environmental concerns have revived widespread interest in production of fuel ethanol from renewable materials. Cellulosic materials are abundant and prominent feedstocks for cheap ethanol production. However, due to recalcitrant structure of these materials, pretreatment is a prerequisite. READ MORE

4. Small-Scale Production of Fuel-Cell Hydrogen
Abstract : The work presented here aims at producing hydrogen for proton-exchange fuel-cell applications from hydrocarbons. This thesis describes an integrated catalytic converter comprising a steam-reforming reactor (heat of reaction supplied by catalytic combustion), a water-gas shift reactor and a preferential oxidation of carbon monoxide reactor, and the work performed on the fuel processing catalysts therein.

5. Diffusive Combustion of Ethanol in a Dual-Fuel Direct Injection Compression Ignition Engine
Abstract : The impact of climate change due to global warming necessitates rapid and extensive measures to enhance the sustainability of the energy and transport sectors. In this context, there are large environmental and societal benefits to be gained by replacing diesel with renewable fuels for road freight transport. READ MORE
