The Effect of Wood Vinegar on Hydrothermal Liquefaction of Cotton Stalk Under CO Atmosphere

High pressure liquefaction of cotton stalk under carbon monoxide atmosphere in water and two kinds of wood vinegar was performed in a high pressure autoclave. The results indicated that the conversion of cotton stalk and yield of liquid product were increased by using wood vinegar as the solvent. Us...

Description
Summary:High pressure liquefaction of cotton stalk under carbon monoxide atmosphere in water and two kinds of wood vinegar was performed in a high pressure autoclave. The results indicated that the conversion of cotton stalk and yield of liquid product were increased by using wood vinegar as the solvent. Using wood vinegar as the solvent, the hydrothermal liquefaction of cotton stalk under carbon monoxide atmosphere was investigated and it was found that, compared with water, wood vinegar could improve the conversion of cotton stalk and yield and heating value of liquid product from 91.56%, 35.75%, and 34.14 MJ/kg to 94.98-97.37%, 48.26-54.23 MJ/kg, and 35.45-37.58 MJ/kg, respectively.
