Fluidized Bed Gasification of Biomass Char by Chemical Looping

Chemical Engineering Transactions, 2021
Biomass gasification is a green and effective process to generate synthesis gas (syngas, CO + H2) with high heating value provided that inert species (e.g. N2) are removed from the products or inherently avoided in the feedstock.
