Product Comparison for Slow and Fast Pyrolysis of Flax Shive
semanticscholar(2022)
摘要
In the current work, a comparison of the composition and properties of products obtained by the slow and fast pyrolysis of flax shive is presented to evaluate the influence of the process mode on the thermal decomposition of agricultural waste. The thermogravimetric studies were carried out to estimate the temperature range of the decomposition of the feedstock main component (cellulose, hemicelluloses, and lignin) and to choose the pyrolysis temperature. It was found that the slow pyrolysis was found to provide the higher conversion depth of the feedstock resulting in the formation of gaseous and liquid products with higher calorific values (9.65 MJ/m3, and 16.51 MJ/kg respectively). Moreover, the solid residue of the slow pyrolysis was characterized by the higher surface area and narrow pore size distribution in comparison with that obtained by the fast process.
