Abstract

Abstract: Hydrothermal depolymerization of Cunninghamialanceolata alkali lignin were conducted in a batch autoclave at temperatures of 250-350 ℃.The components and characteristics of hydrothermal degraded liquid products and hydrochar were investigated by gas chromatography with mass spectrometry (GC/MS),elemental analyzer and Fourier transforms infrared spectroscopy (FT-IR).The results showed that the least residue (18.66%) was collected at 325 ℃.In addition,the relative content of phenols in liquid products was above 80%,and the types and contents of phenols were both increased with the rise of temperature.Guaiacol was the dominant phenol component,represented 17.71 mg/g at 325 ℃.With the increase of reaction temperature, reductions of hydrogen and oxygen contents were observed,while the carbon content increased.The optimum carbon and energy conversion rates at 325 ℃were 79.18% and 79.95%,respectively.The chemical structures of hydrochars were similar to alkali lignin at temperatures below 325 ℃.However,a serious carbonization of lignin was observed when the temperature was over 350 ℃.

Key words: subcritical water, lignin, depolymerization, phenols, hydrochar
