Abstract:Mesoporous titanium dioxide/graphitic carbon microspheres were synthesized by a simple nanocasting route using monodisperse silicon dioxide microspheres as the template. The characterize and the morphology of the titanium dioxide/graphitic carbon microspheres have been analyzed by means of XRD, N2-sorption, SEM, TEM, TG-DTA and EDAX. Indicated by the experimental results and the theoretical analysis, the anatase titanium dioxide nanoparticles of 8-14 nm in diameter were highly dispersed in the graphitic carbon microspheres. The obtained material can be used as catalyst or battery material. | |||

Abstract:A detailed comparative analysis of biomass conversion efficiency for ethanol and methane is provided according to the conversion yield and energy consumption of the two conversion processes. The results demonstrate that net energy yield for methane is 0.50-0.83MJ/MJ fuel more than ethanol during biomass conversion, as all small biomolecule including hydrolysate from carbohydrate, protein and fat can be digested to methane, and only carbohydrate hydrolysate can be fermented to ethanol; the energy consumption for evaporation of less residue in digestion is less than in fermentation, and the energy consumption in removing CO2 from biogas through freezing for methane purification is much less than that in removing water from bioethanol through distillation for purification of ethanol. It was demonstrated that the comparative analysis is more credible than Life Cycle Analysis in screening conversion method for biomass. | |||
