Sammanfattning

The aim of the study was to isolate lignin from spruce wood with an Accelerated Solvent Extractor (ASE) using low concentration of aqueous NaOH and optimize extraction parameters regarding the solvent use. The extraction temperatures were 160°C and 170°C, and pressure was 10 MPa. Extraction was performed for 4 hours total time in 12 cycles per 20 minutes sequence. It was shown that reducing of extraction solvent use by 60% results in decreasing of total yield of lignin only by 5% in case of 170°C and 3% in case 160°C.
