Fast pyrolysis of biomass

An oil sorbent from wood fiber by mild pyrolysis

“…The liquid sorption ability of the pyrolysis solid residues was significantly affected by the temperature ( Table 2). The oil sorption ability was almost constant at a temperature range of 200 to 350 ~ An additional increase in the temperature, however, resulted in a decrease in the oil sorption capacity, indicating that a further degradation of hydrophobic substances generated under the relatively mild pyrolysis conditions occurs at higher temperatures (Graham et al 1984). On the other hand, a steady decrease in the water adsorbency was observed at rising temperature until 500 ~ The decreases at temperature ranges of 200-250 and 300-350 and above 400 ~ may be mainly due to the thermal degradation of hemicellulose, cellulose and lignin, respectively (Kuriyama 1979;Graham et al 1984).…”

Development and validation of CFD models for gas phase reactions in biomass grate furnaces considering gas streak formation above the packed bed

“…The bed height was varied by particle layers from 5 to 15 layers. During typical biomass combustion conditions with air staging the most relevant components released are H 2 O, CO 2 , CO, H 2 and CH 4 [20][21][22]. However, during packed bed combustion, the dominant gas volume flux is from the primary air passing through the packed bed.…”

Catalytic pyrolysis of Phragmites (reed): Investigation of its potential as a biomass feedstock

“…The main decomposition reaction occurred above 200 • C, where the DTG curve indicated two overlapping steps. The first corresponds to the degradation of the hemi-cellulose portion [13] of the reed, while the second corresponds to the decomposition of cellulose. The use of lower heating rates did not improve the resolution of the two steps.…”
