Abstract

Thermochemical liquefaction of Kraft lignin using Ru/Aly(SiO4)x catalyst produced oil at 300, 350 and 375°C under 40 atm. hydrogen, 40 atm carbon monoxide, inert 40 atm. N2 atmosphere and under vacuum (20 mmHg). The effect of temperature and atmospheric condition on carbon based yield(%yield), carbon based conversion( %conversion), mass of carbon and hydrogen recovered as oil (%CHR), H/C and O/C atomic ratio of oil parameters were studied. %yield (94.30±0.05), carbon based conversion (75.60±0.01) and %CHR (60.50±0.05) were highest at 375 °C under vacuum. ANOVA showed that all the parameters at different atmospheres and only %yield, %conversion and %CHR at different temperatures varied significantly. Oil of best quality was obtained at 375 °C under vacuum.
