H
ydrogen is an energy carrier, which stores and delivers energy and produced from fossil fuels and renewable energy
sources such as biomass, wind, solar, geothermal, and hydroelectric power to split water. Biomass gasification is a process
in which biomass is converted into gaseous components by applying heat in the presence of air/oxygen and steam. Within the
scope of this study, tea waste was gasified in the presence of Ni-CeO

catalysts using air as gasifying agents. The Ni-CeO

catalyst was synthesized by the co-impregnation method and characterized by XRD, XRF, SEM and BET techniques. The
effect of gasification parameters such as temperature (650, 850

loading (0-40 wt.%) at constant 3 L/h air flow rate, on
the gaseous product distribution was examined. The main gas components were determined as H

by micro
gas chromatography analyzer. The maximum H
