For the liquefaction technology, aqueous thermal liquefaction of rice, barley, wheat, and rapeseed straws was investigated to compare the amount of heavy oil with catalysts such as $K_2CO_3$, NaOH and KOH in the reaction temperature at ${320^{\circ}C}$ for 10 minutes. The reaction was carried out in a 5,000ml liquefaction system with dispenser and external electrical furnace. Raw materials (160g), 2,000ml of distilled water and 10% (wt/wt) of catalyst to plant residue were fed into the reactor. It was observed that the maximum heavy oil yield was about 29% from the feeding stock, barley straw, with addition of KOH. The caloric values of crude oil from different crop residues were ranged from 55% to 66% relative to the raw materials depend on crop residue. It was appeared that its maximum calorific value from wheat straw was approximately 6190 kcal/kg. Furthermore, in case study of co-solvent with ethanol and bulk-glycerol, it observed that more than 80% of rice hull was decomposed and liquefied in its solvent at 315-${326^{\circ}C}$ for 30 min. For the development of applicable bio-fuel from rice hull, its feasibility is necessary to be carried out for co-solvent soluble portions.
For the pyrolysis technology, to Study the bio-oil production through pyrolysis process of different biomass, three years pilot-scale study was conducted at animal farm of Seoul National University, for evaluating the distribution of bio-oil, bio-char, biogas from pyrolysis process of livestock waste. There are six kinds of biomass used in this study, including rice husk, sawdust, pig waste, dairy waste, beef waste and laying hen manure.
