Alkali ceramics are well-known high temperature CO 2 sorbents in forms of zirconates or
orthosilicates with catalytic tar cracking ability prior to or after carbonation. In this study, Li 2
ZrO 3, Li 4 SiO 4, and Na 2 ZrO 3 were selected as catalyst-sorbent bifunctional materials to
enhance the pyrolysis of sawdust. This study investigated the synergy between the alkali
metal bifunctional materials under pyrolytic conditions. The weight loss data and gas yield
trends in the temperature between 200 and 800° C demonstrated a combined catalytic …

Alkali metal bifunctional catalyst sorbents enabled biomass pyrolysis for enhanced
hydrogen production. In this study, Li2ZrO3, Li4SiO4, and Na2ZrO3 were selected as
catalyst-sorbent bifunctional materials to enhance the pyrolysis of sawdust. This study
investigated the synergy between the alkali metal bifunctional materials under pyrolytic
conditions. The weight loss data and gas yield trends in the temperature between 200 C and
800 C demonstrated a combined catalytic process and gas-solid reaction. A metal carbonate …
