Continuous Operation of a 10 kWth Chemical Looping Integrated Fluidized Bed Reactor for Gasifying Biomass Using an Iron-Based Oxygen Carrier

12.12.2014 | Guoqiang Wei; Fang He; Zhen Huang; Anqing Zheng; Kun Zhao; Haibin Li, Energy & Fuels, 2014

Chemical looping gasification (CLG) was investigated in a 10 kWth interconnected fluidized bed reactor with Fe2O3/Al2O3 as oxygen carriers (OC) and pine sawdust as fuel. The effects of the operation temperatures and sawdust feeding rate on the gas composition, cold gas efficiency, and carbon ...

Quantification of Chemical States, Dissociation Constants and Contents of Oxygen-containing Groups on the Surface of Biochars Produced at Different Temperatures

11.12.2014 | Zaiming Chen; Xin Xiao; Baoliang Chen; Lizhong Zhu, Environmental Science & Technology, 2014

Surface functional groups such as carboxyl play a vital role in the environmental applications of biochar as a soil amendment. However, the quantification of oxygen-containing groups on a biochar surface still lacks systematical investigation. In this paper, we report an integrated method ...

Secondary Organic Aerosol from Aqueous Reactions of Green Leaf Volatiles with Organic Triplet Excited States and Singlet Molecular Oxygen

11.12.2014 | Nicole K. Richards-Henderson; Andrew T. Pham; Benjamin B. Kirk; Cort Anastasio, Environmental Science & Technology, 2014

Vegetation emits a class of oxygenated hydrocarbons - the green leaf volatiles (GLVs) - under stress or damage. Under foggy conditions GLVs might be a source of secondary organic aerosol (SOA) via aqueous reactions with hydroxyl radical (OH), singlet oxygen (1O2*), and excited triplet states ...

Chemical‐Looping Reforming of Methane Using Iron Based Oxygen Carrier Modified with Low Content Nickel

09.12.2014 | Guoqiang Wei, Fang He, Zhen Huang, Kun Zhao, Anqing Zheng, Haibin Li, Chinese Journal of Chemistry, 2014

Abstract Fe2O3/Al2O3 and Fe2O3/Al2O3 modified by low content of Ni (below 2% in weight) oxygen carriers were prepared by mechanical mixing and impregnation method. The synthesized oxygen carriers were characterized by means of X‐ray diffraction (XRD), X‐ray fluorescence (XRF), scanning ...
