Effect of mixed solvent on the sub- and supercritical liquefaction of agricultural waste

Effect of mixed solvent on the sub- and supercritical liquefaction of agricultural waste

Transactions Of The Chinese Society Of Agricultural Engineering: 5, 200-203

The sub- and supercritical liquefaction of rice straw to produce bio-oil with mixed solvent (ethanol-water and 2-propanol-water mixture) was studied in a 1000 mL autoclave at 553-573 K, 6-18 MPa. The results showed that using the mixture could promote the conversion of rice straw below 50%, and inhibit the formation of low boiling point materials. The oxygen content in the bio-oil was decreased with the increase in the ratio of hydrogen donor solvent (ethanol and 2-propanol).
