Abstract
Two ultrasound-assisted delignification processes of the apompo pulp
(Pachira aquatica) were compared. Apompo pulp is a lignocellulosic material with
potential for obtaining bioethanol, the percentage of lignin found in the pulp was
29.77%. The alkaline ultrasound-assisted delignification with NaOH at 60 ° C
presented the best lignin removal with 67.02%, compared to the process of acid
ultrasound-assisted delignification yielding 50.56% removal of lignin. The pulp of the
apompo without delignification process has a 4.84% cellulose, this percentage was
increased in the delignified pulp by sonication with NaOH at 60 ° C obtaining 66.89%
of cellulose.
