Abstract
Biomass briquettes are expanding its reach from domestic stoves to giant power plants. This study aims to evaluate the effect of compositional heterogeneity of bagasse and groundnut shell briquettes on slow pyrolysis kinetics, fast pyrolysis product distribution and time evolution of pyrolysates. The average apparent activation energy of pyrolysis was low for 0.71–1.4 mm particles of bagasse (175.5 kJ mol−1) and 1.4–2 mm particles of groundnut shell (169.3 kJ mol−1). The production of phenolics, furan derivatives, monoaromatics and condensed ring aromatics exhibited marked changes with respect to particle size of biomass and temperature. The phenolic selectivity was more from large biomass particles. The production of aromatic hydrocarbons is correlated with the particle size of biomass, and the extent of secondary reactions is shown to be coupled with heat and mass transport of pyrolysates within the confined pores of the sample. The evolution rate of pyrolysis vapors increased with increasing temperature.
