Energy and Exergy Analysis of Hydrogen Production on Co-Gasification of Municipal Solid Waste and Coal

Abstract

Hydrogen energy is considered as one of the cleanest sources of energy due to its high efficiency. The only combustion product of hydrogen is water. Gasification can be used for the conversion of wastes into other fuels, and it presents an engaging renewable replacement for fossil fuels. This study aims to produce hydrogen as a result of co-gasification of MSW with coal to generate energy during its disposal. The importance of the system has been emphasized by making energy and exergy analyses. Gasification performance and the importance of hydrogen production of municipal solid blended with coal at different ratios (10%, 30%, 50%, 70%, and 90%) were also determined. A numerical model was developed for the co-gasification system. This study implies that gasification can be used for the evaluation of coal with disposal of MSW and conversion of these wastes into energy, without harming the environment.
