When banana fruit was hydrolyzed,the mass amounts of H2SO4
and NaOH consumed were higher than the ethanol mass produced.
These results lead to an economically unviable process,requiring
more research to diminish the amount of raw materials used in the
process.
Water used to dilute H2SO4 in acid hydrolysis and NaOH in the
enzymatic hydrolysis process allows obtaining the adequate
consistency for agitation and the ideal relation between water and
glucose for the fermentation process(150 g/L),in such away that
the yeast can promote the conversion in to ethanol.This diluting
water increases the consumption of supplies and energy,besides
requiring equipment of larger size and increasing distillate
production.
Table5 shows the energy consumed in form of heat and work in
hydrolysis,fermentation and distillation.
The work and heat consumed in the material preparation,
feed stock crushing and shattering(see Fig. 1) were taken into
account for the acid hydrolysis.In the enzymatic hydrolysis,the
energy consumed in the delignification process was considered.
Heat was not consumed in fermentation because this process was
maintained at a temperature lower than 33 C. The highest
consumption of steam corresponded to the distillation process
