摘要

Abstract

The development of a process that could recover biofuel from industrial cellulose waste can not only reduce the negative environmental impacts by using fossil fuels

but also bring a green idea for the waste's disposing. In this study

hydrothermal pretreatment was optimized for cassava anaerobic residue

a cellulosic waste from cassava ethanol industry

to co-utilize xylose and glucose for producing bioethanol. The effect of the main pretreatment conditions

namely

temperature

solid content and time

was explored for the highest recovery of xylose in prehydrolysate and glucose in enzymatic hydrolysate. The single factor experiment results showed that the conditions for maximum xylose recovery in prehydrolysate and glucose recovery in enzymatic hydrolysate were 60℃

75 min

10% solids and 160℃

75 min

10% solids

respectively. Whereafter

response surface methodology (RSM) was applied to further optimize the pretreatment conditions for the maximum theoretical ethanol production through utilizing both xylose and glucose. A treatment at 163℃

for 59 min and with 9.5% solids was found optimal

with the highest ethanol production of

20.2 mg·g

-1

raw material. Furthermore

in order to assess the impacts of the pretreatment on cassava anaerobic residue

the changes in crystallinity and morphology for untreated and pretreated solids were investigated.
