Heat transfer-limited flash pyrolysis of woody biomass: Overall reaction rate and time analysis using an integral model with experimental support

High temperature thermochemical processing of biomass and methane for high conversion and selectivity to H2-enriched syngas

“…The mechanism of lignocellulosic pyrolysis has not been fully deduced due to high feedstock compositional heterogeneity and varying catalytic effect of ash. At high temperature, conversion of the parent biomass material is heat-transfer limited but still very fast (t pyro $ 10 À4 -10 À2 ) depending on particle size and high conversion is readily achieved [63][64][65]. However, high selectivity to synthesis gas is dictated by conversion of condensable volatiles, light hydrocarbon gases, and char.…”

The Influence of Char Preparation and Biomass Type on Char Steam Gasification Kinetics

“…In literature, such an analysis has already been conducted by several authors. For instance, this can include pyrolysis [20][21][22][23][24], pyrogasification [8], and torrefaction [25] at the particle scale. However, most of these studies were performed for fast pyrolysis (HHR) and not slow pyrolysis (LHR).…”
