1. Layer Formation on Bed Particles during Fluidized Bed Combustion and Gasification of Woody Biomass
Abstract : Although more than a hundred papers dealing with the agglomeration problem in combustion and gasification of biomass can be found in the literature, very few studies focusing on the bed particle layer formation process in fluidized bed combustion (FBC) and fluidized bed gasification (FBG) can be found. With increased knowledge of the bed particle layer formation process — i. READ MORE

2. Carbon Recovery in A Dual Fluidized Bed Gasifier
Abstract : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. READ MORE

3. Phosphorus recovery from sewage sludge fluidized bed gasification processes
Abstract : One of the most sustainable pathways of sewage sludge treatment in recent years has been thermal conversion. The benefits of thermal treatment of sewage sludge are the recovery of energy or valuable chemical products, the destruction of harmful organic compounds, the separation of heavy metals from the P-rich coarse ash fraction, and the decreased and sanitized ash volume.

4. Ash Behavior in Fluidized-Bed Combustion and Gasification of Biomass and Waste Fuels : Experimental and Modeling Approach
Abstract : Over the past few decades, a growing interest in the thermal conversion of alternative fuels such as biomass and waste-derived fuels has been observed among the energy-producing companies. Apart from meeting the increasing demand for sustainable heat and power production, other advantages such as reducing global warming and ameliorating landfilling issues have been identified.

5. Use of Bed Materials in Dual Fluidized Bed (DFB) Systems
Abstract : Dual Fluidized Bed (DFB) gasification is one alternative for the production of biofuels. In a DFB gasification process, the bed material plays a crucial role. Primary role of the bed material is to provide the heat needed for the gasification reaction. READ MORE
