Nickel supported on SBA-15 doped with CeO<sub>2</sub> catalysts (Ni-CeO<sub>2</sub>/SBA-15) was prepared, and used for steam reforming of toluene which was selected as a model compound of biomass gasification tar. A fixed-bed lab-scale set was designed and employed to evaluate the catalytic performances of the...</sub>

SiO<sub>2</sub> hollow spheres and low relative permittivity insulation paper handsheets composed of these SiO<sub>2</sub> hollow spheres with different weight percentages were successfully prepared. Low-content SiO<sub>2</sub> hollow spheres were uniformly dispersed in the insulation paper handsheets. The relative permittivity...

In this paper, the promoting effects of ash and biomass gas reburning on N<sub>2</sub>O decomposition were investigated based on a fluidized bed reactor, with the assessment of the influence of O<sub>2</sub> on N<sub>2</sub>O decomposition with circulating ashes. Experimental results show that different metal oxides contained...
