Topic: Oxy-Steam-CO2 Gasification of RDF/Biomass mix to produce the hydrogen-rich producer gas
Background of the Research Work:
The mounting CO2 emission and rapid depletion of fossil fuels are two significant challenges for sustaining growing energy requirements and keeping the environment clean. Biomass gasification using CO2 as a gasifying agent may be one of the alternative techniques to tackle such emerging problems. In our recent studies, air-CO2 and oxygen-enriched air-CO2 biomass gasification are successfully conducted in the autothermal gasifier. The results reveal that the yield of CO in the producer gas increases compared to air gasification, resulting in a higher heating value of the producer gas. In another study, steam was used along with air in a gasifier to increase the hydrogen content of the producer gas. Extensive experimental work was carried out in a downdraft gasifier using air and steam. To summarize, the combination of air-steam, air-CO2, and oxygen-enriched air-CO2 gasification studies were conducted using the biomass.
Brief Description of the proposed research work:
The proposed project envisaged extensive gasification studies using a mixture of oxygen, steam and CO2 as a gasifying agent. It is proposed to use different waste materials, such as agricultural residue (biomass) and refuse derived fuel (RDF), to produce the hydrogen-rich producer gas. The system's performance would be measured in terms of the cold gas efficiency, equivalence ratio and carbon conversion efficiency. The effect of various operating conditions will be found. The project involves using various equipment, such as a Pelletizer, Gasifier, Tar analysis setup, Steam generator, Steam superheater, Gas chromatograph, Thermogravimetric Analyzer, and Bomb Calorimeter. It is also proposed to improve the ASPEN Plus model developed in the previous studies.
Essential Minimum Qualification:
