Hydrogen production based on chemical looping combustion can obtain clean hydrogen with near zero emission of carbon dioxide. This technique can be auto-thermal, making it very promising for hydrogen production. In this paper, the interconnected fluidized beds were established for cold model study, and tests were carried out, aiming at providing some design information for the hot bench. Experiments...
The functionalization and electric properties of graphene by the addition of transition metal atom of Ni to its surface had been investigated computationally using density functional theory with the generalized gradient approximation. The stable geometry adsorption position, binding energy, band gap, density of states, charge transfer of Ni adsorbed on graphene at two different coverages were calculated...
In this paper, the effects of nickel ions concentration (4.0 wt%, 4.5 wt%, 5.0 wt%), carbonization temperature (700??C, 800??C, 900??C), heating rate (5??C/min, 15??C/min, 20??C/min) and particle size (0.1-0.2 mm, 0.2-0.3 mm, 0.3-0.38 mm) on resistivity of char derived from winter wheat straw were studied. The result showed that when nickel loading is 5.0 wt%, carbonization temperature is 900??C,...
Chemical-looping combustion (CLC) is a new method for the combustion of fuel gas with inherent separation of carbon dioxide. The cold interconnected fluidized beds (Oslash100) were set-up for the hot model design in this work. The pressure drop of both air reactor (AR) and fuel reactor (FR) were measured and used for CLC system design. The effects of superficial gas velocity on pressure distribution...
The pyrolysis of straw was one of the important ways for biomass utilization. Chemical structure of straw lignin had great impact on the decomposition process of straw. In this paper, lignin molecule was modeled with an average structure method and optimized with Density Functional Theory (DFT). The most stable conformations of structural units and structural model of straw lignin were obtained by...
The experimental research on removing N2O with biomass gas was carried out in a small-fluidized bed reactor tube. The decomposition rate of N2O and the production rate of NO impacted by reaction temperature, residence time, reburning position, rate of fuel, initial oxygen content of flue gas and the height of material bed were researched. The results showed that the decomposition rate of N2O was more...
