Co-liquefaction of coal and torrefied biomass was performed in a mechanically stirred and electrically heated Parr reactor to evaluate effects of co-liquefaction and torrefaction on product yields and properties. The test samples were coal, red maple, yellow-poplar, torrefied red maple and torrefied yellow-poplar. Sample mixtures of coal-red maple, coal-yellow-poplar, coal-torrefied red maple, and coal-torrefied yellow-poplar were prepared in the wt ratio of 1:1. About 10 g of sample and 100 ml of tetralin were placed inside the reactor. The temperature and hydrogen gas pressure were 300C and 600 psi (cold), respectively. The results showed that oil yields obtained from co-liquefaction of either coal + torrefied red maple, or coal+ torrefied yellow-poplar mixtures were higher than the weighted average yields from coal and biomass separately. During liquefaction synergy between coal and torrefied biomass was observed.
