Bubble Dynamics In A Sand Fluidized Bed In The Presence Of Biomass Pellets, Nicolas Torres Brauer Jun 2020

Bubble Dynamics In A Sand Fluidized Bed In The Presence Of Biomass Pellets, Nicolas Torres Brauer

Electronic Thesis and Dissertation Repository

Given the worldwide concerns regarding fossil fuel availability, global warming, water, and air pollution and economy needs, there is an urgent requirement to develop and implement alternative energies. Biomass gasification can consume vegetal waste to produce syngas, which is a mix of carbon monoxide, hydrogen, and carbon dioxide. When biomass gasification is carried out in a fluidized bed, the process is highly efficient.

The experimental study of the present Ph.D. dissertation took place in a Plexiglas 0.44 m diameter unit, equipped with a CREC Optiprobe system and a video camera. The unit was filled with 200-900 µm sand particles and …


Gasification Of Bio-Oils To Syngas In Fluidized Bed Reactors, Mohammad Latifi Apr 2012

Gasification Of Bio-Oils To Syngas In Fluidized Bed Reactors, Mohammad Latifi

Electronic Thesis and Dissertation Repository

Bio-fuels are renewable and clean which can be used as alternatives to fossil fuels or can be used in combination with them. Biomass is a main source of bio-fuels production: it is a renewable resource and its conversion to energy releases no net CO2 to the environment.

Bio-oil, the valuable liquid product obtained from biomass through pyrolysis, may be either combusted to generate carbon-neutral electricity or converted to a synthesis gas from which chemicals or clean fuels can be produced. Producing bio-oil from biomass and then converting the bio-oil to syngas has several advantages: The bio-oil may be generated …
