摘要：

Five kraft lignins from softwood and hardwood and one softwood lignin from the organocell process were converted into an oil-like product by hydrotreatment at 400-degrees-C for 40 minutes in the presence of different catalysts. The total oil yields varied in the range 49-71% wt of the original lignin feedstock. The highest yield was obtained for organosolv lignin using a catalyst mixture of sulfided NiMo on aluminosilica (M8-81) : Cr2O3 (M9-10) (1:1). Detailed GLC analysis of the low-molecular-weight components in the oil products (the total amounts of 14-38% wt of the original lignin) indicated the presence of various alkyl benzenes, phenols, and polycyclic aromatics.
