Abstract

This work involved the prediction of the concentration profiles and theoretical yields in lignocellulosic biomass pyrolysis under real pyrolysis conditions. The competing reaction model was used and verified by the experimental data of the pyrolysis of oilseed rape straw and sesame stalk. The pyrolysis kinetic behaviors of the pyrolysis of peach branch, cotton stalk, and corn stalk under various conditions were simulated based on the model and their chemical compositions. The influences of the heating rate and final temperature on the theoretical yields of pyrolysis products and the pyrolysis time were obtained. Under the same conditions, the pyrolysis of peach branch gave the highest yield of volatile products, while the pyrolysis of cotton stalk gave the highest yield of char. The method presented in this work enables us to predict the concentration profiles and theoretical yields of different lignocellulosic materials under various pyrolysis conditions.
