Vinasse is a residue of ethanol production from sugarcane. In view of
the problems associated with its disposal, this study aimed to propose a
treatment for vinasse by hydrothermal carbonization. The influence of
temperature (100 to 200 degrees C), acidity (1.7 to 8.3%) and reaction
time (12 to 48 h) on the hydrothermal treatment was evaluated, as well
the characteristics of the solid (hydrochar) and liquid (process water)
products. For the solid product, two hydrothermal carbonization
conditions stood out as leading to higher carbonization and yields.
These conditions were 200 degrees C, 8.3% acidity and times of 12 and
48 h. For the process water, the carbonization reaction at 200 degrees
C, 8.3% acidity and 48 h produced the highest discoloration and 77%
reduction of total organic carbon. Thus, hydrothermal carbonization
proved to be an efficient method to treat vinasse, and the hydrochar
presents potential for use as fertilizers / soil conditioners, and also
the process water after pre-treatment.
