WebApr 12, 2024 · Chemical looping gasification (CLG) is an effective coal utilization technology. In this work, the CLG of bituminite was investigated through fixed-bed batch experiments using NiFe2O4 oxygen carrier (OC) to achieve high-quality syngas. The changes in the phase of the oxygen carrier during the chemical looping reaction and the … WebNov 15, 2024 · Several studies [12], [32], [35] showed that the higher the coal/biomass proportion in blends, the higher the H 2 yields and H 2 /CO ratio in co-gasification-derived syngas (Fig. 2). This mainly attributed to the higher H/C ratio and AAEMs content in biomass/coal than those in PC [32], [36], [37].

Web1 day ago · The high light absorption and low thermal conductivity of the CPAS results in excellent thermal management capabilities (Figures 2 e and S6). Under solar illumination (1 sun), CPAS showed a faster temperature rise, and the surface temperature stably remained above 98 °C, almost 20 °C higher than the CPAS-No porosity surface temperature. WebThe atomic H/C ratio of torrefied biomass under an inert atmosphere tended to be higher than what was obtained under an oxidizing atmosphere for the same temperature conditions (Lu et al. 2012). This result was due to the thermal degradation of elements such as hydrogen and oxygen, associated with the decomposition of wood constituents. how do you start a helicopter
