Solvent treated rice straws (STRS) were catalytically hydrogenated in 1 MPa hydrogen at 200-350°C for 2 hours. Rh-loaded activated carbon (Rh5AC) or Rh-loaded Y type zeolite (Rh5Y) were used as catalysts. Around 19 wt% of raw STRS was dissolved in cyclohexane. After hydrogenation of STRS at 200°C, the cyclohexane soluble component (HS) increased to 44 wt% independent of the catalyst species. When the temperature increased to 350°C, HS decreased to 36 wt% in the case of no catalyst, while HS hardly changed in the presence of Rh5AC and Rh5Y, which were 42 wt% and 44 wt%, respectively. GC-MS spectrum showed that, an aliphatic compounds were derived by opening one cyclic aromatic hydrocarbon using Rh5Y at 350°C. It is considered that Rh5Y is useful for the hydrogenation of STRS at 350°C.
