| Abstract: |
| To achieve clean and efficient cellulose hydrolysis， a plasma-acid-catalyzed cellulose hydrolysis technical solution with simultaneous acid production and cellulose hydrolysis was proposed. The effects of parameters such as working voltage， discharge gap， and reaction time on cellulose hydrolysis were examined. Furthermore， a comparative study of two technological solutions， simultaneous and stepwise acid production-cellulose hydrolysis was also carried out. Additionally， the reaction mechanism of acid-catalyzed hydrolysis of cellulose enhanced by electric field and discharge plasma was elucidated. The results indicated that when the reaction time was 60 min， the simultaneous acid production-cellulose hydrolysis scheme increased the cellulose conversion rate by 10.5 percent points compared to the stepwise scheme， increased the average cellulose conversion speed by approximately 32.7%， and reduced the average specific energy consumption by about 83.3%. Compared with the oxalic-acid-catalyzed cellulose hydrolysis scheme， the glucose yield of the simultaneous technical scheme increased by approximately 20.3%. |
