| 英文摘要 | As a novel biomass gasification technology, chemical looping gasification (CLG) could in situ catalytically crack biomass tar by oxygen carrier (OC). This study compares the reactivity of different OCs (Al2O3, Fe2O3, NiO, NiO+Fe2O3, and NiFe2O4) to crack a biomass tar model compound (toluene) and preliminarily explores the reaction mechanisms of toluene cracked by NiFe2O4 OC. Among five OCs, NiFe2O4 with a homogeneous Fe/Ni dispersibility shows the best reactivity for toluene cracking with a toluene conversion and H-2 yield of 96.83% and 0.91 L/g, respectively. Additionally, on the basis of the dispersibility of active sites on the OC sample surface, the reactivity of the other four OCs to crack toluene shows the sequence NiO+Fe2O3 > Fe2O3 > NiO >> Al2O3. A large amount of carbon deposition, including amorphous carbon and graphitized carbon, is generated during toluene catalytic cracking, while the addition of steam significantly eliminates the carbon deposition. The NiFe2O4 OC shows a dual-function of in situ oxidation-catalysis during toluene cracking. A mechanism of four steps is proposed for the toluene cracking on OCs: (I) toluene cracking at high temperature, (II) reduction of OC, (III) generation of amorphous carbon deposition and (III') formation of graphitized carbon, and (IV) elimination of carbon deposition. |
