Production of Diesel Oil Mixed Fuel by Direct Liquefaction of Wood Biomass Using Diesel Oil as a Solvent

Abstract

Wood biomass attracts attention as a fossil alternative resource. However, the collection of the wood biomass takes cost because the biomass growing region has biased widely. Therefore, it is preferable to convert the wood biomass to an alternative fuel such as diesel oil near where it is discharged. Then, the experiments which use the cellulose and lignin were conducted to clarify the pyrolysis behavior of the wood biomass using the diesel oil as a solvent. Moreover, the physical properties and the combustion characteristic of the diesel oil mixed fuel derived from wood were examined. As a result, the compounds derived from the unit structure of cellulose and lignin were generated by pyrolysis even if diesel oil was used as a solvent. The wood liquefaction concentration in diesel oil mixed fuel was increased when the solvent ratio was decreased. Moreover, this concentration was increased further when the retention time was extended. It was confirmed that the physical properties of diesel oil mixed fuel was suitable to a part of the Japanese Industrial Standards.
