Revealing the influence of chemical compounds on the pyrolysis of lignocellulosic wastes from the Amazonian production chains

摘要

Lignocellulosic wastes from Amazonian crops are promising for the production of biochar. However, there are scientific gaps concerning the thermodegradation mechanisms of widely diverse biomass. This research explored the relationships between the chemical compounds and the pyrolysis behavior of the acai seed, cocoa pod husk, coconut husk, palm empty fruit bunch, and maize cob by thermogravimetric analysis. The cocoa pod husk and palm empty fruit bunch showed the lowest temperatures of initial degradation (= 17% dry basis) and ashes (>= 5.7% dry basis) combined with the lowest contents of holocellulose (= 41% wet basis) at the pyrolysis final temperature of 400 degrees C.
