3Establishment of correlation between reaction kinetics and carbon structures in the char gasification process显示文摘For a gasification process,the char-CO_(2)gasification is the controlling step worthwhile to be deeply investigated.The article chosen corn stalk(CS),poplar sawdust(PS)and bagasse residue(BR)as the typical waste species derived from agricultural,forestal and industrial sources.The char-CO_(2)gasification behavior,reaction kinetics and carbon structure were studied to reveal the intrinsic factors determining the reaction kinetics.Generally,the carbon conversion and maximum conversion rate were influenced by the feedstocks species and char preparation temperatures,as influenced by ash proportion,potassium content in ash and carbon structure of char.The char-CO_(2)reaction for CS was subject more to the catalytic effect of alkali compositions,while pore structure affected more the gasification reaction for PS char.The isoconversional kinetic analysis indicated that the gasification reaction became stable at carbon conversion of 0.5.Subsequently,sectionalized kinetic parameters were calculated for the initial gasification temperature to the temperature reaching 50%conversion.The result showed that high initial gasification temperature increased the char-CO_(2)gasification barrier to hardly start the reaction but accelerate the reaction rate.The carbon structure analyses further clarified that the reaction activation energy was highly related to the microcrystalline structure of carbon,while the reaction rate was more determined by carbon pore structure.Zefeng Ge Xi Cao Zhenting Zha Yuna Ma Mingxun Zeng Yuqing Wu Zenghui Hou Huiyan Zhang 2023Carbon Resources Conversion2023,6,2:0
4Reactivity and performance of steam gasification during biomass batch feeding显示文摘The steam gasification characteristics of poplar sawdust were investigated in a piston fed fixed-bed gasifier,reflecting the batch feeding process of fixed-bed gasifiers in industrial applications.The effects of operating conditions,including steam supply,the flow rate of inert gas,gasification temperature,and feeding rate,on gasification reactivity and performance were investigated online.The major gas product during pyrolysis was CO,followed by H2,CH4,and CO_(2),and the gasification was greatly facilitated by the injection of steam to generate H2.The gasification reactivity and performance were improved with increased steam supply and temperature.The maximum production rate of H_(2)by char gasification was tripled and doubled,respectively,with an increase in steam supply from 50 to 400 mL/min and a temperature rise from 800 to 900◦C,and the time required for complete gasification was also halved.Compared to pyrolysis,the volume fraction of H2 increased from 23%to 37%,and correspondingly,the H_(2)/CO ratio increased from 0.42 to 0.95.Yuna Ma Zefeng Ge Mingxun Zeng Zhenting Zha Yujie Tao Huiyan Zhang 2023Carbon Resources Conversion2023,6,3:0
5In-situ study for the elastic structure evolutions of threedimensional Ir-O framework during the oxygen evolution reaction in acid显示文摘Understanding the dynamic structural and chemical evolutions at the catalyst-electrolyte interfaces is crucial for the development of active and stable electrocatalysts.In this work,β-Li_(2)IrO_(3)is employed as a model catalyst for the oxygen evolution reaction(OER).Its elastic three-dimensional Ir-O framework enables us to investigate the Li^(+)cation dissolution-induced structure evolutions and the formation mechanism of amorphous IrO_(x)species.Electrochemical measurements by rotating ring disk electrode(RRDE)reveal that up to 60%of the measured OER current can be ascribed to catalyst degradation.A series of in-situ X-ray diffraction spectroscopy(XRD),X-ray absorption spectroscopy(XAS),and Raman spectroscopy are conducted.Structure vibration is observed with oxidation states of Ir being reduced abnormally during OER at high potentials.It’s hypothesized that the reversible proton intercalations are responsible for the Ir turn-over mechanism.Results of this work demonstrate a stable and elastic iridate structure and reveal the initial catalyst degradation behaviors during OER in acid media.Jun Qi Xinyu Zhong Huiyan Zeng Chao Wang Zhongfei Liu Jiajun Chen Long Gu Enna Hong Mengxian Li Jiong Li Chunzhen Yang 2023Nano Research2023,16,7:0
