Carbon Dioxide Gasification Of Biochar: A Study On Utilizing Captured Co2 To Mitigate Greenhouse Gas Emission And Improving Carbon Conversion Efficiency, Nnamdi Ofuani
Electronic Theses and Dissertations
With rapidly growing global economies and world population, fossil fuel continues to play a major role in meeting current energy demands. Carbon capture and storage (CCS) technologies have, hence, been implemented to reduce CO2 emissions in the atmosphere. With the implementation of CCS technologies comes the need to utilize the captured CO2. This research, therefore, proposes CO2 gasification of biochar as a viable carbon utilization pathway. With captured CO2 coming at various concentrations, there is a need to understand how CO2 concentration affects biochar conversion to useful products. This study, therefore, evaluates the effects …
Steam Gasification Of Biochar To Produce Hydrogen-Rich Syngas, Nnamdi Ofuani
Steam Gasification Of Biochar To Produce Hydrogen-Rich Syngas, Nnamdi Ofuani
Honors College Theses
A key greenhouse gas (GHG) emission contributing to climate change is carbon dioxide (CO2) emission. This emission is largely due to the use of fossil fuel as a major energy source. Biomass is an alternative energy source. Biochar, a byproduct of the pyrolysis process (of biomass), could be gasified to produce syngas (a mixture of CO and H2). This syngas can further be used to produce different kinds of fuels like biodiesel, bio-gasoline, bioethanol, etc. In the steam gasification of biochar, the quality and yield of syngas is dependent on parameters such as temperature, particle size, …
