Characterization of free radicals by electron spin resonance spectroscopy in biochars from pyrolysis at high heating rates and at high temperatures
(Elsevier, 2016-09-06)The concentration and type of free radicals from the decay (termination stage) of pyrolysis at slow and fast heating rates and at high temperatures (above 1000°C) in biomass char have been studied. A room-temperature ... -
Experimental and numerical characterisation of materials for biomass co-firing
(2017-02-23)As Europe continues to decarbonize its electricity generation capacity, operators of thermal power plants face challenges to which they must adapt including increasingly transient operation and co-firing with biomass. This ... -
Harvesting effects on biomass and nutrient retention in Phragmites australis in a free-water surface constructed wetland in western Ireland
(2007)The aim of this study was to examine the seasonal variation in biomass, total nitrogen (Tot-N) and total phosphorus (Tot-P) content of Phragmites australis in a 3-cell free-water surface (FWS) constructed wetland in western ... -
An integrated approach to trophic assessment of coastal waters incorporating measurement, modelling and water quality classification
(2012)Various protocols have been developed for trophic assessment of coastal waters but most incorporate single value compliance criteria for water quality parameters which, in reality, exhibit significant spatial variation. ... -
Investigation of Biomass Combustion in Grate Furnaces using CFD
(2012-12-12)Channelling is an undesirable phenomenon in the fixed-bed combustion of biomass. It is characterised by an uneven air distribution, and thus fuel conversion, throughout the fuel bed. Attempts to mitigate the channelling ... -
The nature of stable char radicals: An ESR and DFT study of structural and hydrogen bonding requirements
(Wiley, 2018-06-28)Pyrolysis is a promising way to convert biomass into fuels and chemicals. This reaction is complex and inevitably involves a cascade of radical reactions that lead to char formation, in which some radicals become trapped ... -
On the pyrolysis and combustion of furans: quantum chemical, statistical rate theory, and chemical kinetic modelling studies
(2014-06-23)The development of synthetic methods which can convert inedible waste biomass into liquid transportation fuels is an exciting breakthrough which may reduce our dependence on fossil fuels for energy production, and contribute ... -
One way of representing the size and shape of biomass particles in combustion modeling
(Elsevier, 2017-06-29)This study aims to provide a geometrical description of biomass particles that can be used in combustion models. The particle size of wood and herbaceous biomass was compared using light microscope, 2D dynamic imaging, ... -
Potassium and soot interaction in fast biomass pyrolysis at high temperatures
(Elsevier, 2018-04-02)This study aims to investigate the interaction between potassium and carbonaceous matrix of soot produced from wood and herbaceous biomass pyrolysis at high heating rates at 1250°C in a drop tube reactor. The influence of ... -
Spatially explicit economic and environmental optimisation of bio-SNG production systems integration with the Irish gas network
(NUI Galway, 2019-11-08)Biomass-derived synthetic natural gas (bio-SNG), produced from biomass through gasification and cleaning and conditioning of syngas, is an energy carrier compatible with the existing gas infrastructure and appliances, is ...
