The effect of feedstock composition and taxonomy on the products distribution from pyrolysis of nine herbaceous plants

Popis výsledku v původním jazyce

The effect of feedstock composition and taxonomy on the product distribution from pyrolysis of nine herbaceous plants was evaluated. Specifically, eight members of Poaceae family (five non-hybrid and three hybrid grasses) and one member of Fabaceae family were pyrolyzed in a fixed bed reactor to a final temperature of 700 oC. All samples resulted in a medium-energy CO2-rich gas and a phenol-rich liquid. The type of lignin rather than the overall lignin content was found to be the factor predominantly influencing the composition of phenols yield. All nine herbaceous plants produced char with a suitable C/N ratio; eight plants produced char with of high polarity; and only one sample (i.e., mountain brome) resulted in char with a sufficient aromaticity to be applied to soil. A low carbonization was associated with a high content of inorganic elements that were most likely deposited on the char's surface and blocked vaporization. The product distributions were found to be dependent on (i) the chemical and biochemical composition of feedstock, (ii) the secondary reactions of liquid and char, and (iii) the taxonomy of the grassland biomass species. Red clover from the Fabaceae family was found to be the most distinct, followed by mountain brome from the Triticodae group (Poaceae family) and the remaining members of the Poodae group (Poaceae family). The least divergence was found between the hybrid samples.
