Waste Biomass Based Carbon Aerogels Prepared by Hydrothermal-carbonization and Their Ethanol Cracking Performance for H2 Production

Biomass occupies a significant proportion of municipal solid waste. For the high-value processing waste biomass, hydrothermal-carbonization method was chosen because advantages effective and mild conditions. Four typical types biomass (banana peel, mangosteen orange pomelo peel) were used in this work to prepare carbon aerogels (CA) via treatment for cracking ethanol. kinds CA all had good performances ethanol reaction improved yield H2 from 21 wt% about 40 wt%. The banana peel-based aerogel (BPCA) showed best performance reaction; it cracked obtained 41.86 H2. mechanism by revealed: On one hand, self-cracking due extension residence time, which benefited abundant pores CA. other heterogeneous occurred on surface where inorganic components, mainly Ca, Mg, K, can promote bond-breaking reorganization CO2 byproducts also fixed Ca improving positive reaction.
