Small-Scale Batch-Fed Biomass Gasification and Combustion
Small-scale solid biomass-fuelled cookstoves are highly important to satisfy the energy demand of nearly half the world’s population. With this as a main application, biomass provides the majority of renewable energy worldwide. However, traditional cookstoves, which emit vast amounts of emissions …

Development of a biomass gasification pre-treatment system
This project was focussed on drying and feeding timber-yard waste for a gasifier and the assessment of the feedstock drying on the gasifier performance. This required a thermodynamic model to be developed in order to assess the effect of drying as was highlighted in the literature survey. A heat …

Investigation of sustainable hydrogen production from steam biomass gasification
Hydrogen is a by-product of the gasification process and it is environmentally friendly with respect to pollution and emission issues when it is derived from a CO2-neutral resource such as biomass. It is an energy carrier fuel and has flexibility to convert efficiently to other energy forms to be …

Utilization of Char from Biomass Gasification in Catalytic Applications
Utilization of biomass as an energy source is likely to increase in the near future. One way to recover energy from biomass is via gasification, which enables the production of electricity, heat, chemicals, or fuels such as synthetic natural gas or gasoline. The desired product from gasification is …

Multiscale simulation of methane assisted fluidized bed biomass gasification
… drop-in transportation fuels. Fluidized bed biomass gasification (FBBG) is one of the most promising options for the thermochemical conversion of lignocellulosic biomass to synthetic liquid fuels. When biomass is introduced into the high temperature bed (700-900 °C), it rapidly devolatilizes …

Biomass gasification in small scale plants: experimental and modelling analysis
The technologies for the use of biomass as an energy source are not always environmental friendly process: wood combustion, for example, can be a rather a dirty process that causes the release in air of several dangerous compounds. For those reasons it is important to develop approaches aimed at …

Co-gasification of coal and biomass
Gasification is thermo-chemical conversion technology in which complex organic polymers present in feedstock react with limited oxygen supplied by steam or air. The gasification reaction produces CO2 (Carbon-dioxide), H2 (Hydrogen), CO (Carbon-monoxide), CH4 (Methane) and other lower hydrocarbons. …
