Abstract

Abstract

Select ZnCl₂ as catalyst for hydrogenation and liquefaction in the autoclave, study polarity and hydrogen of solvent for the liquefaction yield of lignin sulfonate and products by GC-MS and infrared spectroscopy. Yield analysis shows, solvent's polar favor for lignin conversion, hydrogen donor solvent can improve the yield of light distillate, the highest conversion of lignin under water and the highest yield of light distillate under the methanol conditions, increased 2.0-times and 1.9-times compare to lowest yield of 1,4-dioxane solvent;GC-MS analysis showed, medium polarity solvents was well to neutral fraction stability, hydrogen donor solvent tetralin can release of hydrogen to binding and stability the radical intermediates,Ethanol have the neutral product of the relative content of 48.76% relative to the minimum 2.2 times the water solvent systems. Infrared analysis showed, in response to alcohol solvent, tar products of hydroxyl peak intensity increased.
