Product distribution from solar pyrolysis of agricultural and forestry biomass residues
Solar pyrolysis of pine sawdust, peach pit, grape stalk and grape marc was conducted in a lab-scale solar reactor for producing fuel gas from these agricultural and forestry by-products. For each type of biomass, whose lignocellulose components vary, the investigated parameters were the final temperature (in the range 800 degrees C-2000 degrees C) and the heating rates (in the range 10-150 degrees C/s) under a constant sweep gas flow rate of 6 NL/min. The parameter influence on the pyrolysis product distribution and syngas composition was studied. The experimental results indicate that the gas yield generally increases with the temperature and heating rate for the various types of biomass residues, whereas the liquid yield progresses oppositely. Gas yield as high as 63.5wt% was obtained from pine sawdust pyrolyzed at a final temperature of 2000 degrees C and heating rate of 50 degrees C/s. This gas can be further utilized for power generation, heat or transportable fuel production. (C) 2015 Elsevier Ltd. All rights reserved.
