Effect of Process Parameters on Hydrogen Production and Efficiency in Biomass Gasification Using Modelling Approach

Hydrogen is considered as an attractive clean fuel for the future. Hydrogen production via biomass steam gasification is receiving attention due to its sustainability and zero net carbon emission. Coupled with in-situ CO2 adsorption, this process has been proven to be environment friendly. The paper...
