In this study, coal fly ash was functionalized, using a simple onestep process (loading with Al3+ and sulfonation), to yield a solid acid catalyst (S/AlCFA) with strong acid sites. The catalyst was then used to produce furfural from xylose in a biphasic system (H2O(NaCl)/tetrahydrofuran). The furfural yield reached 82% at 180 °C60 min with catalyst/xylose ratio of : (w/w). With the ...

Biomass gasification is an attractive technology and one of the pathways for producing hydrogen. Due to the variable seasons and low calorific value of biomass, the addition of coal in the gasifier is suggested because coal has a high calorific value and carbontohydrogen ratio. In general, the gaseous product obtained in gasification always contains a high amount of carbon dioxide, therefore ...

Torrefied biomass is superior to any nontreated biomass in the offgassing behavior and is not subject to rotting, molding, or decomposition. Once densified, torrefied biomass shares many of the characteristics of coal (Järvinen and Agar 2014). The torrefaction step represents an additional unit operation in the biomass processing chain.
