Abstract
The non-edible biomass attracts attention as a fossil alternative resource because it is reproduced in a short term and absorbs CO2 when it grows up. The fundamental examination of A-type heavy oil production from non-edible biomass by hydrolysis and pyrolysis was performed using mixed solvent of mineral oil and pure water. The hydrolysis can omit a dehydration process and make the pyrolysis in relatively mild reaction conditions. It may produce a high yield of A-type heavy oil at low cost. It was proved as a result of examination that A-type heavy oil of low polarity was produced at a high yield when mixed solvent of mineral oil and pure water was used, because the hydrolysis progressed in low temperature and the pyrolysis with dehydration progressed in high temperature. Furthermore, it showed a tendency that yields of water solvent fraction and gas rose when a quantity of pure water was increased and the yield of residue rose when a quantity of pure water was decreased. It became necessary to examine the influence of reaction pressure to the product yield because the steam pressure changed with a quantity of pure water.
